Questions requiring a NHTSA specialist will be routed to the correct office through this process to ensure the correct person is involved with your request. Please give us a turnaround time of 2-4 weeks to get back to you about any inquiries that you have already submitted while we make this transition.

Publishing of material within the NHTSA Manufacturers’ Information Database (MID) may require additional input based on our review of the material. Please ensure that you build adequate review time into your submittal process prior to initiating production. At a minimum, manufacturers should plan for a 30-day review period for all submissions. Timing on approvals and postings could exceed this timeframe based on complexity of the submissions or any issues regarding its content.
