1. Which of the following is not a rule for using turn signals?

Signal early.

Signal continuously.

Cancel your signal once your turn or lane change is complete.

Don’t signal unless another vehicle is close.

Always signal before a turn or lane change. Begin signaling well in advance of the movement and keep the signal on continuously during the turn. If it is not self-canceling, make sure to turn your signal off after your turn or lane change is complete.

2. If you must make a quick stop while transporting liquids, one safe option is to:

Turn while braking.

Apply the emergency brake.

Apply the brakes with minimal pressure.

Use the stab braking method.

If you must make a quick stop to avoid an accident while transporting liquid cargo, it may be a good idea to use the stab braking method. Remember that attempting to steer quickly while braking may cause your vehicle to tip over, especially if it has a high center of gravity.

3. When inspecting the engine compartment, you should not:

Check the engine oil level.

Check the coolant level in the radiator.

Drain the brake fluid.

Check the windshield washer fluid level.

When inspecting the engine compartment, you should check the oil level, coolant level, and windshield washer fluid level, among other things.

4. Class 1, Class 2.1, and Class 3 items should not be placed in a trailer with:

A heater.

An air conditioner.

Other items.

Batteries.

The use of cargo heaters is not always permitted. When transporting materials that are categorized as Class 1 (Explosives), Class 2.1 (Flammable Gas), or Class 3 (Flammable Liquids) materials, heaters are generally prohibited.

5. If oil and water build up in your vehicle's air tanks, the brakes:

May not work correctly.

May feel squishy.

Will squeal loudly when used.

Will be extremely sensitive.

Air tanks should be drained daily to remove water and oil buildup. An excess of oil and water in the air tanks can interfere with proper brake function.

6. To control a surge, brakes should:

Not be used.

Not be released too quickly after stopping.

Be used firmly and then released.

Be used with the parking brake.

To help reduce the risk of front-to-back surge when stopping a tank vehicle, keep steady pressure applied to the brakes. Do not release them too quickly after coming to a stop.

7. What can be a clue that a shipment may contain hazardous materials?

The shipper is a business you might expect to deal with hazardous materials.

The last shipment you picked up was labeled as hazardous.

The packaging looks damaged.

The road is made of gravel.

One clue that a shipment may contain hazardous materials is that the shipper is in a line of business that you would expect to involve hazardous materials. Examples of such businesses include paint dealers, chemical suppliers, scientific supply houses, pest control companies, agricultural suppliers, and dealers in explosives, fireworks, or munitions.
