This document contains the lidar speed-measuring device performance specifications developed by the National Highway Traffic Safety Administration (NHTSA) through a Cooperative Agreement with the International Association of Chiefs of Police (IACP) and in consultation with the National Institute of Standards and Technology (NIST), Office of Law Enforcement Standards (OLES). Because this document is designed as a development and procurement aid, it is highly technical.
This document supersedes the Model Minimum Performance Specifications for Lidar Speed Measurement Devices (DOT HS 808 214, February 1995) and all subsequent reversions.
By defining minimum performance requirements and verification procedures, this technical document establishes a baseline for acceptable traffic lidar speed-measuring device performance. Citizens, courts, and law enforcement officers should be assured that lidar speed-measuring device models, determined by test to comply with these performance specifications, will provide the high-quality service they require.
Lidar equipment buyers should use these performance specifications as minimum specifications when developing purchasing criteria. We suggest these specifications be incorporated into procurement documents requiring that lidar speed-measuring devices offered for purchase meet, as a minimum, these specifications.
Manufacturers are encouraged to produce lidar speed-measuring devices that meet or exceed these performance specifications.
These performance specifications are subject to continuing review. Technical comments and recommended revisions are welcome. Send suggestions to:
Before citing these performance specifications, or any part of them, users should verify they are referencing the most recent edition of this document.
NHTSA believes these performance specifications for lidar speed-measuring devices will assist law enforcement administrators to access the accuracy and reliability of lidar devices they plan to purchase. NHTSA also believes these performance specifications and testing protocols will increase the confidence of the public, the courts, and law enforcement officers in the accuracy and reliability of lidar speed-measuring devices.
