1 . If turning to avoid a hazard:

You should brake hard.

You should not brake as it may cause the wheels to lock.

You should turn very sharply.

You should not brake while making a quick turn to avoid a hazard. Doing so could cause your wheels to lock and make your vehicle skid out of control.

2 . When approaching a vehicle for a pre-trip inspection, a driver should look under the vehicle:

To see if the vehicle is on an incline.

To see if there are any fresh fluids on the ground.

To see if the vehicle is in a parking spot.

When approaching your vehicle before an inspection, make note of its general condition and ensure that it is not damaged or leaning. Look under the vehicle for fresh leaks of oil, grease, or fuel. Check around the vehicle for hazards to movement, such as people, other vehicles, or low-hanging wires or tree limbs.

3 . Anti-Lock Braking Systems (ABS):

Are not used on trucks.

Are only used on tucks carrying hazardous materials.

Allow drivers to stay in control when braking.

An Anti-Lock Braking System (ABS) helps prevent wheels from locking up during a hard application of brakes.

4 . If a driver has stopped on the road and is placing triangles to warn other motorists:

The triangles should be held between the driver and oncoming traffic.

The triangles should be carried behind the driver's back to prevent them from being seen by other drivers until they are placed.

The triangles should be held as low as possible.

For your own safety, when placing reflective warning triangles, you should carry them between your body and the oncoming traffic.

5 . Distracted driving can be avoided by:

Pre-programming radio stations.

Smoking while driving.

Eating while driving.

Distractions while driving can be physical (such as reaching for an object), mental (such as making conversation with a passenger), or both (such as holding a phone to send texts). Strategies to help you avoid distracted driving include pre-programming radio stations; planning out your route in advance; avoiding complex or emotionally taxing conversation while driving; adjusting your mirrors before setting out; and not eating, drinking, or smoking while behind the wheel.

6 . Which of the following is not a cause of hydraulic brake failure?

Loss of hydraulic pressure

Brake fade on long hills

Downshifting

Most cases of hydraulic brake failure come from one of two causes. The brakes may fail due to a loss of hydraulic pressure or due to overuse on long hills, causing the brakes to fade.

7 . If a vehicle is carrying hazardous cargo, placards must be placed:

Only on the front of the vehicle.

On the front, rear, and sides of the vehicle.

Only on the driver’s side of the vehicle.

Placards must be placed on the front, the rear, and both sides of a vehicle carrying hazardous cargo. They must be readable from any direction.
