1. A driver should always:

Stay in their lane.

Have an emergency plan.

Stay in the left lane.

Drive above the speed limit.

While driving, you should continually scan the road ahead to spot potential hazards well in advance. Make emergency plans for how to deal with the hazards in the event that they become dangerous.

2. If transporting explosives, you may leave your vehicle unattended:

In a rest area.

At a truck stop.

On private property.

In a safe haven.

When transporting hazardous materials, you may leave your vehicle unattended in a safe haven. A safe haven is a location that has been approved for parking unattended vehicles that are loaded with explosives.

3. If a tire fails, you should:

Loosen your grip on the steering wheel.

Immediately apply the brakes.

Check your tires after coming to a complete stop.

Turn sharply off the road.

In the event of tire failure, hold the steering wheel firmly. Stay off the brakes and let the vehicle slow down on its own. Once the vehicle has slowed considerably, you should brake very gently, pull off the road, and stop. Check your tires after coming to a complete stop.

4. When an engine is started:

The brakes should be locked up.

Warning lights should come on and then quickly turn off.

The coolant temperature will decrease.

The hood must be open.

After a vehicle is started, the warning lights and buzzers should go out after a few seconds. If the warning signals do not turn off, there may be something wrong with the vehicle.

5. Proper coupling technique:

Is the same on all vehicles.

Is essential to the safe operation of a vehicle.

Block the driver in with your vehicle.

Stop after the crash scene and report the driver’s aggressive behavior to the police.
