1 . Of the following, which is not a recommended way to spot potential signs of trouble?

Watching the gauges

Using your senses

Checking critical items only at the beginning and end of a trip

During a trip, you should regularly make checks to ensure that your vehicle is operating properly. Check the instrument panel and gauges; look at your mirrors; and examine the tires, cargo, and lights. Use all of your senses and be alert for anything that could be an early indication of trouble.

2 . Having anti-lock brakes on only one axle:

Will not make a difference in braking.

Will provide increased control in braking.

Will likely cause the air brakes to malfunction.

If a vehicle has anti-lock brakes on just one axle, the driver will still have more control during braking than they would without any anti-lock brakes.

3 . Unsafely reaching for a phone is:

Acceptable if you are driving without a passenger.

Acceptable if you plan to use a hands-free feature.

Unacceptable even if you plan to use a hands-free feature.

If you must use a mobile phone while driving, it must be in close proximity to you and easily reachable while you are securely fastened into your seat. It is dangerous and non-compliant to unsafely reach for a mobile phone, even if you plan to use a hands-free feature when speaking on the phone.

4 . Load hazardous materials:

Near heat sources.

Away from heat sources.

Away from shadows.

Always load hazardous materials away from heat sources. Be aware of regulations on explosive or flammable materials that prohibit them from being loaded in cargo spaces with heaters.

5 . If an aggressive driver is involved in a crash down the road, you should:

Pull over and yell at them.

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

Block the driver in with your vehicle.

If you observe a crash involving an aggressive driver, you should stop a safe distance from the crash scene, wait for police to arrive, and inform them of the aggressive behavior you witnessed.

6 . If you identify hazardous materials leaking while you are driving, you should:

Continue driving to find a phone booth and call the National Response Center.

Park the vehicle.

Leave the area to find help.

If you discover that a cargo of hazardous materials is leaking from your vehicle, you should park the vehicle as soon as possible. The longer you continue driving, the longer the trail of contamination becomes. While this creates potential danger and harm to others, it also increases clean-up expenses.

7 . Before a trip, you can make sure air flows to all trailers by:

Checking for moving air inside of each trailer.

Listening for air at the rear shut-off valve.

Feeling for air at the front shut-off valve.

Before a trip, ensure that air in the air brake system reaches all trailers. Do this by waiting for air pressure to build, then sending air to both the emergency and service lines and opening the shut-off valves on the rear of the last trailer. If air escapes from the shut-off valves in the rear of the combination, the air is being supplied to the entire vehicle.
