Know if DOT testing applies.

Answer a few quick questions to see if DOT testing may apply.

Do your drivers operate commercial vehicles for business purposes?

Examples include hauling freight, transporting property, or transporting passengers.

Which best describes you?

This helps separate a carrier's responsibility from an individual driver or leased owner-operator situation.

Are you leased onto another motor carrier?

If a driver or owner-operator operates under another carrier's authority, that carrier is usually responsible for the DOT testing program.

Do any drivers operate vehicles that require a CDL?

A CDL is commonly required for certain heavier vehicles, combinations, passenger vehicles, or placarded hazmat transportation.

Does any vehicle meet one of these conditions?

Select everything that fits. This step appears because many carriers are not sure whether a CDL is required.

Do drivers operate CDL-required vehicles?

Semi trucks, CDL hotshots, placarded hazmat, passenger CDL vehicles, etc.
