The enforcement process can become an opportunity to strengthen safety programs.
Expert support helps analyze, respond to, and strategically navigate NOPV proceedings.
A Notice of Probable Violation (NOPV) from the DOT is serious—but it’s not the end of the road. This formal notice outlines alleged violations and potential penalties, and it starts a strict 30-day countdown for your response.
Your Options Under 49 CFR Part 107, Subpart D
Within 30 days of receiving the NOPV, you can:
Admit the violation under §107.315.
Submit an informal response under §107.317.
Request a hearing under §107.319.
If you don’t respond, you waive your right to contest the allegations. The Chief Counsel can then issue orders or penalties as outlined in the notice.
Strategies for a Strong Response
Review the alleged violations carefully—are they factually accurate?
Consider whether the cited regulation was interpreted correctly.
Gather documentation that supports your position.
If necessary, work with a consultant to prepare your response or represent your case.
