North Carolina CDL DMV Knowledge Test Class A 2

Tar in road pavement often rises to the surface of the road, or "bleeds," in very hot weather. Watch for such areas because they can be very slippery.

Low beam headlights allow you to see about 250 feet ahead of your vehicle. When driving at night, adjust your speed so that you will be able to stop in the distance illuminated by your headlights.

During the CDL vehicle inspection test, you must be able to inspect your vehicle and explain to the examiner what you are inspecting and why.

Before inspecting under a vehicle's hood, make sure the parking brake is engaged and/or the wheels are properly chocked.

When accelerating, speed up smoothly and gradually so your vehicle does not jerk. Rough acceleration can cause mechanical damage.

A large vehicle may need to swing right to make a left turn. If an intersection has two left turn lanes, the driver should choose the righthand land to begin their turn.

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.

A Gross Vehicle Weight Rating (GVWR) is the value specified by the manufacturer as the loaded weight of a single vehicle.

A common cause of vehicle fires in the aftermath of an accident is the improper use of flares near spilled fuel. Use flares with caution.

Gross Vehicle Weight Rating (GVWR) is the weight specified by the manufacturer as the maximum weight of a single vehicle and its load.

If you are being followed too closely, you should increase your following distance, avoid making quick moves, and avoid relying on tricks (such as flashing your lights) to help other drivers pass. Speeding up may only increase the danger by causing the tailgater to continue tailgating you at a higher speed.

Placards are diamond-shaped warning signs that are placed on the outside of vehicles carrying hazardous materials. Placards are used to identify the specific hazard classes of the cargo being carried.

During the vehicle inspection skills test, you will need to explain to the examiner what you are inspecting and why.

Strong winds can make it difficult to keep a vehicle in its proper lane. Strong wind can be a particular problem when a vehicle is being driven out of a tunnel.

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.

If you need to make an emergency stop, you can use either the controlled braking method or the stab braking method. It's important to brake in a way that keeps your vehicle in a straight line but will still allow you to turn if necessary.

An encroachment during the basic vehicle control skills test is when an exercise boundary line is touched or crossed by any portion of the applicant's vehicle. Every encroachment will be counted as an error.

In newer vehicles with air brakes, the parking brakes are controlled by a diamond-shaped yellow knob. Pull the knob out to activate the parking brakes and push it in to release them.

When turning quickly to avoid colliding with a hazard in the roadway, you should always keep both hands on the steering wheel. You must have a firm grip on the wheel to be able to turn quickly.

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

You may be asked to complete a parallel parking maneuver into a parking space that is to the left of your vehicle. You should drive past the parking space before backing into it while bringing the rear of your vehicle as close to the rear of the space as possible. Your vehicle should be completely within the boundaries of the space.

To avoid engaging in dangerous and aggressive driving behavior, you should relax and accept any delays that arise throughout a trip. To help avoid the stress of arriving late to a destination, plan for likely delays when planning your drive.

When checking a header board during the vehicle inspection test, you should ensure that it is secure, free of damage, and strong enough to contain cargo.

When making a left turn, you should wait until you reach the center of the intersection before actually beginning to turn. Due to off-tracking, the left side of your vehicle could hit another driver if you begin turning too early.

Passing parked delivery or postal trucks can be dangerous because the driver may be in a hurry and pull into traffic without warning, or may they suddenly step out of the vehicle without checking for other traffic.

To correct a drive-wheel braking skid, you should first remove your foot from the brake pedal to allow the locked wheels to begin rolling again. Quickly steer in the direction you want to go, then countersteer to prevent your vehicle from skidding in the opposite direction.

Tires should never have too much air pressure. Be sure to check your tires' air pressure with a gauge during inspections.

If you use your brakes too much when traveling on a steep downgrade, they may overheat and become less effective. To avoid causing your brakes to overheat on a steep hill, you should rely on engine braking.

ABS is equipped in addition to a vehicle's normal braking system and it neither increases nor decreases the vehicle's braking capability. ABS activates during hard applications of the brake pedal in order to prevent wheels from locking up.

To reduce the risk of developing aggressive driving behavior, you should take measures to manage your stress. One strategy to do this is to simply take a deep breath and accept your circumstances if you realize you will be late to your destination.

The height of a vehicle's center of gravity is very important. A high center of gravity (cargo piled up high or heavy cargo on the top of a load) increases the possibility of your vehicle tipping over.

Federal and state laws require drivers to inspect their vehicles before every trip, regardless of length.

When using your turn signals, you should signal well before the turn or lane change, signal continuously throughout the turn or lane change, and cancel the signal after you have completed your move.

Always change lanes slowly and smoothly. If you did not see drivers who are already using the lane you wish to occupy, this will give them a chance to get out of your way or honk their horns to alert you. Always signal when changing lanes.

In an air brake system, the air storage tanks must be drained to remove accumulated water and compressor oil. Failing to do so can cause damage. Manually operated drains should be used at the end of each day of driving.
