Your company cannot transport hazardous materials until registered. If your company has failed to register for any previous years, you will need to register for any missed years and pay for those as well. DOT has the option for your company to register for up to three years at a time.
If you are transporting hazardous materials, certificates of registration are required to be kept in your vehicle at all times. These will be required during roadside inspections. Failure to have one in the vehicle, or failure to have an updated certificate, could result in a fine of up to $37,500 per day.
⚠️ What’s at stake: Operating hazmat vehicles without current DOT registration carries fines up to $37,500 per day. Roadside inspection violations can result in vehicle impoundment. Transporting certain bulk quantities (>6,614 lbs solids, >792 gallons liquid) without DOT Security Plans triggers additional penalties. Multiple violations lead to expedited federal sanctions.
In addition, copies of the certificates of registration are to be kept for three years at your place of business and must be available for inspection.
Fees that are collected from DOT registrations are used to pay for grants and state and Indian tribe programs related to hazardous materials emergency response planning and training.
