Colorado CDL Permit Test - Tank

Large combination vehicles take longer to stop when they are empty than when they are loaded. The decreased weight causes a vehicle's wheels to have decreased traction on the surface of the road.

In the event of a leak in a cargo of hazardous materials, do not continue to drive any longer than is necessary for safety. Continuing to drive would result in a larger area becoming contaminated. Instead, park the vehicle, secure the area, stay with the vehicle, and send someone to get help.

Driving while fatigued can be extremely dangerous. Strategies for preventing drowsiness while driving include getting a full night's sleep before a trip; having someone ride with you so you can take turns driving; scheduling trips for times during which you are normally awake; and avoiding medications that may cause drowsiness.

Steering wheel play of more than 10 degrees (about two inches of movement at the rim of a 20-inch steering wheel) can make it difficult to steer.

A vehicle inspection report allows a driver to inform the motor carrier of issues that could affect the safe operation of a vehicle. If required, the driver should fill out a vehicle inspection report after every day of driving. They should make note of any issues that could affect the safety of the vehicle or that could lead to a mechanical breakdown.

Railroad crossings that are not controlled by any type of traffic control device are known as passive crossings. The decision to proceed across tracks at a passive crossing is entirely up to the driver.

For the first step of a vehicle inspection, you should review the last inspection report on your vehicle, if there is one. The carrier should have repaired any problems noted on the report.
