Aggressive driving is the act of operating a motor vehicle in a selfish, bold, or pushy manner and without regard for the rights or safety of other road users.

Cargo covers should not flap in the wind. A flapping cover could tear loose entirely, exposing the cargo, and potentially blocking your view or the view of other drivers.

Backing a truck is always dangerous because the driver may not be able to see everything behind them. CMV operators should avoid backing whenever possible.

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.

When inspecting a vehicle, you should check for required emergency equipment, including at least one fire extinguisher.

Hydroplaning is an effect in which a vehicle's tires lose traction with the surface of the road and instead glide along a layer of water. There does not have to be a large amount of water on the road for this to occur. Hydroplaning can begin at speeds as low as 30 mph.

To avoid becoming fatigued on a long trip, you should take a break after every 100 miles or two hours of driving. Driving through the night, or during any other time when you would normally be asleep, raises the danger of fatigue.
