Black ice is a thin layer of ice that is clear enough for the road surface to be seen through it. Be alert to black ice any time the temperature is below freezing and the road surface looks wet.

If your vehicle begins to hydroplane, do not apply the brakes. Instead, slow down by releasing the accelerator and pushing in the clutch. This will help you to regain traction.

Applicants seeking a hazardous materials endorsement must undergo a threat assessment conducted by the Transportation Security Administration (TSA).

Be sure to activate the appropriate turn signal well in advance of a turn or lane change. Signal continuously throughout the turn and make sure to cancel the signal after the turn is completed, if your vehicle doesn't have self-canceling signals.

When exiting your vehicle during the basic vehicle control skills test, you must face the vehicle and maintain three points of contact at all times. If your testing vehicle is a bus, you must maintain contact with the handrail. Exiting the vehicle incorrectly may result in automatic failure of the basic vehicle control skills test.

An operator should drive with care when transporting a cargo of hanging meat. Such a load is unstable, both because it has a high center of gravity and because the swinging of the meat can affect the driver's handling of the vehicle.

You should always complete an after-trip inspection of your vehicle at the end of a trip, day, or tour of duty. Complete a vehicle inspection report, if required.

The suspension system performs the vital functions of holding up the vehicle and its load while keeping the axles in place. Defects in the suspension are therefore extremely dangerous.

Friction inside a brake drum is caused when the brake shoes and linings push against the inside of the drum. The friction in the drums will slow and stop the vehicle.

An Individual Vehicle Distance Record (IVDR) must include information about the distance traveled by a vehicle and the amount of fuel purchased. The required distance information includes the origin and destination points of the trip and the Vehicle Identification Number.

Cargo with a high center of gravity makes a vehicle more likely to tip over than cargo with a low center of gravity. For this reason, it is important that the weight of cargo be distributed as low as possible.

You should cover your cargo to protect people from the cargo if it spills, as well as to protect the cargo from the weather.

If you must stop on the side of the road, make sure to use your four-way emergency flashers. This is particularly important at night.

You may have to swing right to safely make a left turn. If there are two left turn lanes available at an intersection, you should always begin your turn in the rightmost lane.

During the on-road driving test, do not stop, change gears, pass another vehicle, or change lanes while any part of your vehicle is in a railroad crossing.

Pre-trip inspections should be conducted in the same way every time. This will reinforce the steps, making it less likely that you will forget to inspect something important.

It is important that vehicles are not top-heavy, if at all possible. A top-heavy vehicle is at an increased risk of rollover. Place the heaviest pieces of cargo underneath lighter pieces of cargo.

If the low air pressure warning signal comes on while you are operating a vehicle with air brakes, you should stop and safely park the vehicle as soon as possible. It is essential that you are able to stop safely while you still have some braking power remaining.

When backing with a trailer, begin by turning the steering wheel in the direction opposite of the turn. Once the trailer starts to turn, reverse the direction of the steering wheel to follow the trailer.

To obtain a hazardous materials endorsement, you must submit your fingerprints and pass a background check.

However you choose to deal with a brake failure on a downhill slope, it is important that you make your decision as quickly as possible. The longer you wait to act, the faster your vehicle will be moving, and the harder it will become to stop.

Use your low beam headlights when traveling near other drivers at times when it is difficult to see, such as at dawn, at dusk, or in poor weather conditions. Using the high beam setting under certain conditions could make it difficult for other drivers to see.

There are two air brake systems in a dual air brake system. The systems share a set of brake controls, but each system has its own tanks, hoses, and lines.

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.

You should finish each exercise with your vehicle in the exact position described by the examiner. You can be penalized for failing to complete an exercise exactly in the manner described by the examiner, potentially resulting in failure of the basic control skills test.

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.

An Anti-Lock Braking System (ABS) helps to provide additional control during hard braking, but does not necessarily shorten a vehicle's stopping distance.

If you think the road surface may be becoming icy but you are not certain, you can open your window and feel the front of the side mirror, mirror support, or antenna. If ice has formed on any of these items, the road is likely becoming icy as well.

There are several reasons why driving at night is more difficult than driving during the day. It is more difficult for drivers to see hazards, the glare of headlights can affect drivers' vision, and there are more fatigued drivers on the road.

In an air brake system, the air compressor governor controls when the air compressor pumps air into the air storage tanks.

Regrooved, recapped, or retreaded tires are prohibited on the front wheels of a bus.

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.

When approaching your vehicle for an inspection, you should look underneath the vehicle for fresh leaks of oil, coolant, grease, or fuel. Seeing a fresh puddle of any of these fluids could indicate a safety issue with your vehicle.

Foundation brakes are used on each wheel of a CMV. The most common type of foundation brake is the s-cam drum brake.

When stopping, it is best to gradually press down the brake pedal.
