Before you start the test, please answer the question below regarding your insurance status.

Without insurance you will not be able to drive in Michigan

1. Failing to drain air tanks could result in:

Water accumulations freezing and causing brake failure.

Squishy brakes.

Too much air collecting in the tanks.

In an air brake system, the air tanks must be periodically drained to remove accumulations of water and compressor oil. If water is not removed, it could freeze in cold weather and cause brake failure.

2. As the driver of a truck carrying a load, you are responsible for all of the following, except:

Inspecting the cargo.

Recognizing poorly balanced weight.

Knowing the phone numbers of all fire departments along your intended route of travel.

It is the driver's responsibility to inspect their cargo; recognize overloading or poorly balanced weight; know that the cargo is properly secured and does not obscure the driver's view; and know that the cargo does not restrict access to emergency equipment. The driver is responsible for their cargo even if they were not the one who initially loaded and secured the cargo.

3. When starting an engine, oil pressure should come up to a normal level:

Within seconds.

Within five minutes.

After about three minutes.

Look at your truck's gauges when starting the engine. The oil pressure in an engine should come up to a normal level within seconds of the vehicle's engine being started.

4. If a vehicle's Anti-Lock Braking System (ABS) is malfunctioning:

The vehicle will have no brakes.

The vehicle will still be able to brake.

The vehicle will likely travel faster than usual.

An Anti-Lock Braking System (ABS) intervenes to reduce brake pressure if there is a risk of wheel lockup. If the ABS isn't working, the vehicle's basic braking functions are not affected. A driver should continue to drive and brake in a normal manner.

5. When loading cargo, weight should be placed:

As high as possible.

As low as possible.

As far back as possible.

A vehicle is vulnerable to tipping over if its center of gravity is too high. To prevent this, you should distribute the weight of your cargo evenly and as low as possible.

6. Alcohol can be removed from your system:

By exercising.

By drinking coffee.

By waiting.

The liver removes alcohol from the body at a fixed rate, so the only way to sober up after consuming alcohol is to allow your body time to remove the alcohol on its own.

7. If there is a fire in your vehicle, you should not:

Park in an area away from buildings, trees, brush, and other vehicles.

Pull into a service station.

Notify emergency services of your problem and your location.

In the event of a vehicle fire, you should leave the road and stop in an open area. Do not pull into a service station as fuels at the service station could catch fire. Report the fire and your location to emergency services.
