Colorado CDL Passenger Endorsement: Prohibited Practices Test 2026

Some things simply are not allowed when passengers are aboard, and this Colorado CDL passenger prohibited practices test for 2026 makes those lines clear. Fueling with riders on board, leaving the bus running unattended in the wrong situation, and hauling certain cargo are the kinds of prohibited practices the P endorsement enforces. Knowing the prohibited practices keeps a driver on the right side of the rules.

This section drills what a passenger driver must never do, and why each restriction exists to protect riders and the public. The Colorado passenger prohibited practices questions test whether you can recognize a forbidden action even when it seems convenient in the moment.

Colorado fixes the number of passenger questions itself; the Colorado CDL Manual is where that total is written down. Study the list of restrictions there, then use this passenger prohibited practices test to lock them in before your 2026 Colorado CDL.
