NHTSA Interpretation File Search

Overview

NHTSA's Chief Counsel interprets the statutes that the agency administers and the standards and regulations that it issues. Members of the public may submit requests for interpretation, and the Chief Counsel will respond with a letter of interpretation. These interpretation letters look at the particular facts presented in the question and explain the agency’s opinion on how the law applies given those facts. These letters of interpretation are guidance documents. They do not have the force and effect of law and are not meant to bind the public in any way. They are intended only to provide information to the public regarding existing requirements under the law or agency policies. 

Understanding NHTSA’s Online Interpretation Files

NHTSA makes its letters of interpretation available to the public on this webpage. 

An interpretation letter represents the opinion of the Chief Counsel based on the facts of individual cases at the time the letter was written. While these letters may be helpful in determining how the agency might answer a question that another person has if that question is similar to a previously considered question, do not assume that a prior interpretation will necessarily apply to your situation.

  • Your facts may be sufficiently different from those presented in prior interpretations, such that the agency's answer to you might be different from the answer in the prior interpretation letter;
  • Your situation may be completely new to the agency and not addressed in an existing interpretation letter;
  • The agency's safety standards or regulations may have changed since the prior interpretation letter was written so that the agency's prior interpretation no longer applies; or
  • Some combination of the above, or other, factors.

TEXT: Four Tampa Bay shops sued for violating safety codes

-- In a move that could cripple Florida's booming auto-tint industry, the federal government has sued four Tampa Bay tint shops for violating national traffic safety codes.

But dealers say they are in compliance with Florida's own law on window tinting and vow to fight for more relaxed tinting standards.

The U.S. Justice Department, on behalf of the National Highway Traffic Safety Administration, filed four separate lawsuits Wednesday in federal court in Tampa.

Named as defendants are Seminole Solar Systems, Inc., 69 Ulmerton Road in Largo; Window Kote, 3801 16th St. N in St. Petersburg; Solar Graphics Inc. 3337 22nd Ave. S in St. Petersburg; and Allied Glass Tint Inc., 1404 N. Armenia in Tampa. Two Orlando -area tint shops also were sued in separate federal court actions in Orlando.

Each complaint charges the businesses with installing window film on cars that allows less than 70 percent of natural light to pass through. Each shop has tinted at least 800 cars since 1986, the suits claim, making each shop liable for $ 800,000 in fines, the maximum allowed under the relevant federal regulation.

Drivers of cars already tinted would not be affected by the lawsuit, but could still be ticketed by police enforcing Florida's statute on window tint.

Tim Hurd, a National Highway Traffic Safety Administration spokesman in Washington D.C., said an investigation begun in July 1987 found a large concentration of tint dealers operating in Central Florida.

The lawsuits are the first and only of their kind, Hurd said.

Auto tinting "presents a safety problem because it reduces the ability to see what's coming at the car," Hurd said. "We've also had complaints from state law enforcement officials."

Police have long disliked the practice of tinting car windows because it makes it difficult to see inside vehicles.

But the treatment remains extremely popular with drivers in Sun Belt states, who say the window film protects interiors, reduces heat and glare, and makes cars look better.

Phil Hoffman owns Window Kote in Largo and franchises three other shops under that name. His Largo shop tints about 4,000 cars a year. He said Wednesday that he was surprised by the lawsuits.

Drivers of cars already tinted would not be affected by the lawsuit, but could still be ticketed by police enforcing Florida's statute on window tint.

Hoffman said the four area shops named as defendants all voluntarily allowed federal transportation officials to inspect their records in 1988. He said they were told at the time that their installations violated the federal regulation, but that his own attorney said since Florida law allowed the darker tint, the practice was legal.

A 1984 Florida statute allows tinting that allows as little as 35 percent of natural light to enter front side windows, and that allows as little as 18 percent of outside light through back windows. No tinting is allowed on windshields.

TEXT:

Thank you for your letter to Secretary Skinner on behalf of your constituent, Mike Dunn. You inquired about a school bus passenger restraining device marketed by Mr. Dunn. The National Highway Traffic Safety Administration received an inquiry concernin g a similar device in 1988. A copy of our responses, which detail the requirements applicable to such a device, are enclosed. I will summarize those requirements below.

The device being marketed by your constituent, "a safety bar" for school bus passengers, consists of a padded metal bar which is attached to the seat back of the seat in front of the seat whose occupants are to be protected by the safety bar. The bar is hinged to swing up to allow entry and exit of the occupants. The hinge mechanism also allows the bar to drop slightly from its lowered position upon impact in an attempt to reduce the likelihood of abdominal injury. The device operates much like the p assenger restraint bars found on certain amusement park rides.

As explained by the enclosed letters, federal law does not prohibit the installation of your constituent's product on school buses as long its installation and use would not destroy the ability of the required safety systems to comply with the Federal Mo tor Vehicle Safety Standards (FMVSS). If the safety bars are to be installed in any new school bus, the manufacturer of the bus would have to certify that the bus with the safety bars installed complied with the impact zone requirements set forth in S5. 3 of FMVSS No. 222, School bus passenger seating and crash protection (49 CFR Part 571.222).

As the enclosed letters explain, the use of the safety bar would not obviate the need for a school bus with a GVWR of 10,000 pounds or less to comply with FMVSS No. 208, Occupant crash protection (49 CFR Part 571.208). That standard requires that such v ehicles be equipped with either safety belts or automatic restraints at all passenger seating positions.

In addition, as explained in the enclosed letters and information sheet, the manufacturer of the safety bars would be considered a manufacturer of motor vehicle equipment within the meaning of the National Traffic and Motor Vehicle Safety Act (15 U.S.C. 1381 et sec.). Such a manufacturer is responsible for conducting a notification and remedy campaign if the company or this agency decides that the product contains a defect related to motor vehicle safety, or that it does not comply with an applicable s afety standard.

I hope you have found this information helpful. Please do not hesitate to contact me if you have any further questions.

TEXT: In the automobile-window tinting business, the government says the law is black and white. The defendants say it's not so clear.

The Justice Department sued six Florida companies Wednesday for violating federal safety standards. It says the companies, including two in Central Florida are selling and installing tinting film that is too dark and unsafe for motorists.

But some window tinters say it's the federal government that has kept them in the dark.

They say they've been following Florida law that requires film to let at least 35 percent of the light pass through driver and front seat windows of cars, 1 and 20 percent through rear and back-seat windows.

The company owners say they were unaware they were violating a federal law that requires automobile tint to let through at least 70 percent of the light

David Spearin, operator of Shakespearin Inc. of Holly Hill, said he was shocked when told he was a defendant in the suit. He said he was unaware of the differences in the federal and state laws until told by a reporter Wednesday

"We've never been asked to cease and desist," said Spearin, operator of five car stereo and window tinting stores in Central Florida. "We've never been informed there was any problem. This is amazing.

We are complying with the [Illegible Word] in Florida. If the federal standards are different than the state standards, then they should get together."

Blue Skies Protects, Inc., of Orlando, which operates as Flying Window. Tinters at [Illegible Word]. Semoran Blvd also was named in one of the suits.

"This is total insanity," said Suzanne Turner owner of Blue Skies, "I really feel picked on. I haven't done anything bad." Officials of the National Highway Traffic Safety Administration in Washington and the U.S. attorneys office in Tampa could not be reached for comment Wednesday.

Turner and Spearin said they have lost business because they have refused to install film that is darker than allowed by state law. They argue they are legitmate window-tinting firms, compared with other operations that are willing to break the law t o make a buck.

Turner said she received an inquiry from the National Highway Traffic Safety Administration a few years ago asking about tinting products and records. She and her husband packed up their records and flew to Washington to investigate the query, but th e agency representative they met with was "incredibly vague," she said.

Her husband, Tom Turner, who operates a Longwood window-tinting company, said federal transportation officials told the couple the Florida guidelines were considered substandard under federal law. He said he informed the manufacturers of the film, wh o are fighting the government standards.

"They should go after the window-tint manufacturers," Spearin said. "They're the ones selling it. We're just the installers."

A spokesman for Martin Energy Products in Fort Lauderdale, makers of car window tint film with more than 300 customers in Florida, said the tinting industry is trying to get uniform legislation passed that would mirror Florida's standards.

"We are before Congress right now trying to make federal standards a 35 percent law," said company spokesman Glenn Hale.

Hale, Spearin and the Turners say that window tint is not the hazard the government says it is. The tint placed on passenger windows of cars prevents glass from shattering in an accident, they say.

Florida Highway Patrol Lt. Randy Harper in Orlando said troopers often write tickets for motorists who have dark windshield film that violates Florida law. Car owners who tint their rear windows are required to install mirrors on both sides of the veh icle, he said. Those who illegally install film darker than allowed by law face up to 60 days in jail and $ 500 in fines.

Harper said dark tinting has contributed to many night accidents investigated by his agency and has prevented motorists from being able to observe the actions of other drivers helpful for defensive driving.

"It's also a problem in law enforcement walking up to a car and not being able to see what is inside," Harper said.

They should go after the window-tint manufacturers. They're the ones selling it. We're just the installers.

ATTACHMT: Letter dated 1-12-90 to Stephen P. Wood from Samuel Kimmelman

TEXT:

This is in reply to your letter of January 12, 1990. ideal is a manufacturer of aftermarket variable load turn signal flashers, certified as complying with Motor Vehicle Safety Standard No. 108, for use as replacements for original equipment flashers.

You call our attention to a turn signal indicator system used in some vehicles over the past few years. The system consists of three indicators that flash sequentially when the turn signal is activated. If a turn signal lamp fails, the flasher changes to a higher flash rate so that the third indicator is not illuminated. This signifies to the driver that the turn signal lamp has failed. HoWever, due to differences in operating characteristics between ideal's flashers and original equipment flashers used in these systems, ideal cannot "guarantee our flashers will provide sufficient 'on' time to allow the dash board indicator arrows to reach the 3rd stage as the corresponding turn signal lamps flash within the requirements" of Standard No. 108. You ask whether Ideal can "list our variable load flashers as replacement flashers for vehicles having three (3) growth stage dash board turn signal arrows?"

If ideal cannot be sure that all its flashers will provide the performance for which the triple indicator system is designed, it would seem appropriate to state that these flashers should not be used in such systems. While use of ideal's flashers would n ot appear to affect the operation of the turn signal system itself, the warning feature of the indicator system might not be realized.

However, these remarks are outside the coverage of Motor Vehicle Safety Standard No. 108. As a manufacturer of replacement equipment, Ideal is required only to certify that its turn signal flashers conform to the requirements of Standard NO. 108, which in this instance are those of SAE Standard J590b Automotive Turn signal Flashers, October 1965, incorporated by reference in standard No. 108. Compliance with these requirements is verified through laboratory testing. There is no requirement in Standard No. 108 that ideal ensure that its flashers are compatible with the design of any indicator system in which they may be used.

TEXT: On January 25, 1989, Porsche submitted petitions for exemption from the Vehicle Theft Prevention Standard under 49 CFR Part 543 for its 1990 (MY) 911 and 928 models. NHTSA granted the petitions on May 26, 1989, on condition that any modifications to the alarm systems require Porsche to re-petition the NHTSA unless the modifications could be characterized as de minimus.

Porsche is planning to make the modifications set forth below to the alarm systems of MY 1991 911 and 928 model lines. For the following reasons, the changes described below should be considered de minimus:

1) The alarm control unit will be integrated with the central locking and interior light control units in order to save space and simplify the vehicle electrical system.

2) The system changes will be virtually transparent to the operator. The system will still be armed by locking either door with the key.

3) All of the same points of entry (i.e., door, hood, hatch, etc.) will be monitored by the system and the engine disabling and alarm features are the same. The system will be as protected and tamper resistant as the current system.

4) The new system will also monitor the glove box for opening. If the glove box is opened while the alarm is armed, the alarm will be set off (this is important for convertibles).

5) The system will have improved diagnostic capability in order to enhance serviceability.

6) The system will have the capability to accept other inputs (such as motion sensors) if they are desired in the future.

Based on the above, we believe that the alarm systems as modified contains all of the functions and features on which NHTSA based its decision to grant the exemptions. For that reason, we respectfully request a ruling from you that the planned modificat ions are de minimus and thus, obviating the need for a formal petition.

If you have any questions, please call me at (702) 348-3198.

TEXT: The owner of a local automobile window tinting business says a federal lawsuit is not going to stop him from serving his customers.

"It's business as usual," David Spearin said Thursday. "It's steady as she goes."

ShakeSpearin's Inc. of Holly Hill was one of six Central Florida businesses named in civil complaints filed Wednesday by U.S. Attorney Robert W. Genzman of Tampa on behalf of the U.S. Justice Department.

The lawsuits charge the companies with violating federal safety standards by installing window tinting film that is too dark and unsafe for motorists.

Federal regulations require automobile glass that allows at least 70 percent light through its surface. The complaints seek to stop the businesses from violating the regulation [Illegible Word] impose civil [Illegible Word] for the violations.

Spearin and owners of several [Illegible Word] cal window-tinging operations [Illegible Word] follow state standards, which [Illegible Word] stringent, and Spearin said he was unaware of the tougher federal rules. State law permits tinting that allow s only 35 percent of the light to pass through windshield and front-seat windows, and 20 percent through rear and back-seat windows.

"We've always complied with Florida statutes and will continue to do so," Spearin said.

Officials with the National Highway Traffic and Safety Administration in Washington, which oversees federal highway safety rules, could not be reached for comment Thursday.

Owners of other local companies in the automobile detailing business not named in the lawsuits said they wore nontheless concerned.

"The National Highway Traffic and Safety Administration sent us some form a few years back pertaining to the light transmission qualities of the tinting, but that was the last I heard about it until now," said Ray Gordon, owner of Auto Appearance Cent er in South Daytona.

"Tinting that lets 70 percent of the light in is basically what cars come with," he said. "It's just ridiculous why they're doing something like this."

Gordon said he would start abiding by the federal standard, at least until the issue is resolved.

"It's going to wind up scaring customers away right at the peak of the season," he said. "But a law is a law so I'll follow it."

Lance Puckett, owner of Stardrive Detailing and Tinting of Holly Hill, said he got started in the tinting business only recently.

"I've heard the federal law was [Illegible Word] but nobody told me what it was, [Illegible Word] ways followed the state law," he don't do big volume on window but maybe it's time to start [Illegible Word] gurt."

Solar-X of Daytona was the [Illegible Word] in Volusia County to offer tinting, according to owner Brian [Illegible Word]

"My family got into this businesses years ago and there's always [Illegible Word] continuity between federal law [Illegible Word] law," he said. "Instead of wasting payers' money trying to prosecute people, the federal government [Illegible Word] get with the states and draft a [Illegible Word] law."

Martin Energy Products of Fort dale, makers of tinting film, are Congress to make the federal [Illegible Word] percent.

Smith said he's lost business by to install film darker than allow state law.

"I turn people away almost [Illegible Word] said. "I don't do those gangster [Illegible Word] know Dave (Spearin) doesn't either of the smaller shops, for an [Illegible Word] they'll paint your windows [Illegible Word] want. But I see the Florida la w very sufficient and it's going to [Illegible Word] as usual for me."

TEXT:

Thomas Built Buses, Inc. has recently received a copy of your letter of August 8, 1989, to Ms. Karen Finkel, Executive Director of the National School Transportation Association, Springfield, Virginia. Thomas is vitally concerned with the opinion you ha ve expressed in your letter regarding the requirements for school buses that, by definition are engaged in "interstate commerce", to comply with the non-school bus requirements for emergency exits as specified in FMVSS No. 217, (571.217), as released on September 1, 1973.

Our concern is rooted in the fact that because of the special requirements of school bus seating, it is patently impossible, in many critical applications, to comply with these requirements.

As you are aware, the NHTSA has revised FMVSS 217 subsequent to the September 1973 issue date. We refer primarily to the revisions made effective October 26, 1976 and February 10, 1982. You are probably not aware of two letters of interpretation receiv ed by Thomas Built Buses, Inc. from the Office of Chief Counsel of NHTSA in 1977 and 1984, as well as recent interpretations received from the legal staff of Womble, Carlyle, Sandridge et.al., all of which Thomas believes are in disagreement with the opi nion expressed in your letter of August 8, 1989 to Ms. Finkel. We present for your consideration the following items:

1. Prior to the revisions to FMVSS 217 (571.217) by the NHTSA in 1976 and 1982, the language of FMCSR 393.61(b) (2) requiring that "a bus, including a school bus....must conform with NHTSA's 571.217"....left no alternative but that the schoo l bus "engaged in interstate commerce" would have to meet the non-school bus requirements since, because of the exclusion of school buses by NHTSA from these requirements, only non-school bus requirements were spelled out. The 1976 and 1982 Revisions to FMVSS 217 by NHTSA removed the exclusion for school buses spelled out in the September, 1973 version of FMVSS 217 and added specific emergency exit requirements for school buses of all classes.

Currently, with no revisions to the language of section 393.61(b) (2), the reference of 393.61(b) (2) to 571.217 now points the school bus user to the school bus requirements, and not to the non-school bus requirements.

2. In response to questions from Thomas Built Buses, Inc. to the NHTSA re application of FMVSS 217 to school buses, the NHTSA Chief Counsel (Mr. J. J. Levine, Jr., NOA-30, September 29, 1977) verified that paragraph S5.2 containing the requirements for buses other than school buses does indeed apply only to non-school buses. A copy of this letter is attached.

3. In response to questions from Thomas Built Buses, Inc. to the NHTSA, again re applications of FMVSS 217 to school buses, the NHTSA Chief Counsel (Mr. Frank Berndt, letter to Mr. Ron Marion dated July 5, 1984) verified that even in the cas e of school buses that are also used for "charter buses or general transit vehicles", these buses do not need to meet the requirements of FMVSS 217 for non-school buses. A copy of this letter is attached.

4. In a separate review of the facts of this matter by the legal firm of Womble, Carlyle, Sandridge & Rice, Winston-Salem, N.C., Thomas Built Buses, Inc. has been advised that in their opinion, school buses are not required, in any instance of usage or travel, to comply with the non-school bus requirements of FMVSS 217. A copy of this letter is attached.

Mr. Trentacoste, in light of the information submitted herein, Thomas Built Buses, Inc. respectfully requests that your office review and revise your letter of August 8, 1989 to Ms. Finkel to bring it into agreement with these interpretations.

We appreciate your taking the time to review this material, and look forward to hearing from your office on this matter.

TEXT:

This responds to your letter and to your telephone conversations with this agency concerning school bus safety. You intended your letter to function as a "petition" to amend S4.1 of Federal motor Vehicle Safety Standard 222, School Bus Seating and Crash Protection (49 CFR S571.2229), and Highway Safety Program Guideline 17, Pupil Transportation Safety (23 CFR S1204.4).

Ms. Fujita of my staff has discussed with you our difficulty in understanding your petition. With respect to Standard 222, your letter did not clearly set forth the facts which you believe establish that an order is necessary (as specified for petitions under 49 CFR S552.4(c)); nor did you set forth the substance of the order which you think NHTSA should issue (S552.4(d)). (Ms. Fujita has since sent you a copy of these requirements.) This information helps NHTSA adequately understand and evaluate pet itions. In the absence of that information, we have attempted to surmise the essence of your request, based on your past correspondence with NHTSA. Please advise us whether our surmise is correct. To avoid the possibility of our acting on the basis of incorrect assumptions, we will take no further action on this matter until we hear from you.

Paragraph S4.1 of Standard 222 states:

The number of seating positions considered to be in a bench seat is expressed by the symbol W, and calculated as the bench width in inches divided by 15 and rounded to the nearest whole number.

In your past correspondence, you've expressed concerns about overloaded school buses and the manner in which manufacturers designate the passenger capacity of a school bus. you've suggested that S4.1 of Standard 222 contributes to the overloading of scho ol buses, in that it permits manufacturers to designate a 39-inch bench seat as having three, and not two, seating positions. In our responses, we explained that a 39-inch bench seat is calculated as having three seating positions under S4.1 to ensure t hat the seat will be constructed to provide adequate crash protection when occupied by the maximum number of passengers. it is not Standard 222's intention to require or suggest that the seat should be occupied by the maximum number of passengers, althou gh a 39-inch bench seat is capable of carrying three passengers with a hip width (sitting) of a 5th percentile adult female. We also said that the number of seating positions derived from S4.1 is not meant to be a measure of the absolute capacity of the bus for all sizes of occupants. A bus may be capable of easily accommodating 65 preschool or elementary students, but only 43

high school students. (Examples of letters regarding your concerns are NHTSA's letters to Senator Donald Riegle (July 5, 1985), and Congressman Howard Wolpe (February 23, 1989).) We would like to emphasize that Standard 222 does not address the capacity of a school bus. The decision regarding how many passengers should be carried by a school bus is made by the States.

NHTSA recommends in Highway Safety Program Guideline 17 that States should plan school bus routes such that each occupant is provided a seat and to eliminate standees. However, the guideline is non-binding on the States, and NHTSA does not have the autho rity to regulate how school buses are loaded.

In your current letter, you imply that manufacturers are improperly calculating the number of seating positions on a bench seat. Information available to NHTSA indicates that manufacturers are calculating the positions in accordance with S4.1.

Since you seem dissatisfied with S4.1, you appear to believe that S4.1 should be changed. We believe you wish to suggest that S4.1's calculation of seating positions should be based on the hip width of a high school student. Under your suggestion, a 39- inch bench seat would be considered to have two seating positions, and not three (as presently calculated). You apparently believe that calculating three positions on a 39-inch seat is one position too many, in that "one third of the school buses' rated capacity (is placed) outside of the head, and leg impact zones' of compartmentalization. We would like to point out that your suggested change would have the effect of reducing the applied forces and energy for testing the seat, thereby creating a poten tially less safe environment for passengers. You also seem to believe that designating three positions encourages school bus operators to overload the seat. We understand you to suggest that S4.1 be amended such that the number of positions on a bench seat is calculated as the bench width in inches divided by 15 and rounded down to the nearest whole number.

As I stated earlier in this letter, the preceding discussion constitutes our understanding of your "petition" on Standard 222. Before we consider your petition further, you must inform us if we are correct in our understanding.

With respect to Guideline 17, there is no available formal procedure under which interested persons may petition for a change to NHTSA's Highway Safety Program Guidelines. However, the agency is preparing to issue a Federal Register notice requesting pu blic comments on proposed revisions to the guideline. We will forward a copy of your letter to the appropriate docket once the notice is published.

I hope this information is helpful.

TEXT:

Thank you for your time today concerning our phone conversation pertaining to the 1985 non-complying Mercedes 280S vehicle which has arrived at the Port of Palm Beach from Freeport, Bahamas.

As you explained to me today, this vehiele, being imported solely for repair and return to the Bahamas, does not require the posting of a DOT bond for 150 percent of the value.

We will make formal entry with U. S. Customs, and post a Customs bond to cover the liability.

U.S. Customs wants a reassurance that they will not be held accountable if for some unforseen happening, this vehicle is not properly exported.

Your further advice in this matter would be greatly appreciated. Thank you.
