Questions

      
How do I report a semi truck driver?

      
If anyone is in danger right now, call 911. For something you already saw, note the time, place, direction and the company name or USDOT number, then file with FMCSA's National Consumer Complaint Database at nccdb.fmcsa.dot.gov. This page turns your notes into a report you can paste there.

      
How do I report a semi truck driver for reckless driving?

      
Describe only what you saw: the lane change, speed, tailgating or phone use, with where and when it happened. Tick the matching boxes in the form. Skip guesses about the driver, such as their mood or whether they were tired.

      
Where is the company name or USDOT number on a semi?

      
Most tractors show the company name and USDOT number on the cab door. Trailers often carry a separate unit number. You can check a carrier on FMCSA's SAFER Company Snapshot.

      
Can I call instead of filing online?

      
FMCSA lists a phone line for complaints: 1-888-DOT-SAFT (368-7238), weekdays 8am–8pm ET. Have your report open so you can read the facts out.
