Hawaii CDL DMV Knowledge Test Class A 2

If you have an Anti-Lock Braking System (ABS) equipped on only the tractor, only the trailer, or only one axle, you will still have more control over the vehicle when braking than you would without ABS. You should brake normally.

During a pre-trip inspection, you should check for emergency equipment, including spare electrical fuses; three red reflective triangles, six fuses, or three liquid burning flares; and at least one properly charged and rated fire extinguisher.

Skills tests must be taken in the type of vehicle the applicant plans to drive. The applicant is generally responsible to supply the testing vehicle.

Eating heavy foods before driving or keeping the temperature in a cab too high can cause a driver to become drowsy while behind the wheel. Exercising and maintaining a healthy diet will help a driver to stay alert while driving.

When planning to turn left at an intersection, make sure you have reached the center of the intersection before beginning the turn. If you turn too soon, off-tracking may cause the left side of your vehicle to hit another vehicle.

You should never assume that you will hear an approaching train. The train operator may fail to sound the horn, or the use of a train's horn may be prohibited in a specific area. Even if the train does sound its horn, noise from inside your own vehicle may prevent you from hearing the train until it is dangerously close.

If you are convicted of any traffic violations while driving any vehicle, you must notify your employer within 30 days of the conviction. This rule excludes parking violations.

When turning on your vehicle's engine, the lights on the dash should come on and then turn off. If the ABS malfunction light stays on, the system is not working properly. In the case of a truck with a trailer, if the yellow light on the left rear of the trailer stays on once the engine has been started, the system is not working properly.

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.

When approaching your vehicle before an inspection, make note of its general condition and ensure that it is not damaged or leaning. Look under the vehicle for fresh leaks of oil, grease, or fuel. Check around the vehicle for hazards to movement, such as people, other vehicles, or low-hanging wires or tree limbs.

You should always slow to a safe speed before entering a curve. Slowing while within the curve could cause a skid.

Driving with dry bulk tanks requires special care because they usually have high centers of gravity. It is also important for drivers to be prepared for the contents to shift in transit.

Your vehicle pulling to one side or the other while you are braking can indicate trouble with the brakes.

If you are being tailgated, you should increase the distance between your vehicle and the vehicle ahead of you. This reduces the need for you to make sudden changes in speed or direction while making it easier for the tailgater to pass your vehicle.

Before a trip, you should check each slack adjuster after parking, setting wheel chocks, and disengaging the parking brake. Pull the slack adjusters to make sure that they do not move more than about one inch from where the push rod is attached. If they move more than one inch, they may be out of adjustment and will need to be fixed.

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.

When inspecting a trailer coupling, you should make sure the fifth wheel locking jaws are closed around the shank of the kingpin, not the head of the kingpin.

Potential warning signs of fatigue include difficulty focusing, frequent blinking, or heavy eyelids; yawning repeatedly or rubbing your eyes; daydreaming; wandering or disconnected thoughts; trouble remembering the last few miles you've driven; missing exits or traffic signs; having trouble keeping your head up; drifting from your lane; following too closely; hitting a shoulder rumble strip; or feeling restless and irritable.

An air brake system has a safety relief valve, which releases air from the tanks if the pressure gets too high. If the valve must operate, something in the system is wrong and should be addressed by a mechanic.

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

Splitting driving responsibilities with a second driver lowers the chance that either of you will drive while fatigued. You can also reduce the risk of fatigue by avoiding heavy foods and keeping the interior of the cab cool.

Brakes out of adjustment will fade before those that are properly adjusted. Brake adjustment must be checked frequently to help prevent brake issues.

On flatbed trailers and trailers without sides, cargo must be tied down to prevent it from shifting or falling off in transit.

If a vehicle is equipped, an application pressure gauge shows how much air pressure is being applied to the brakes. This gauge can help a driver identify if their brakes are beginning to fade.

To ensure that your vehicle does not roll backward when beginning to move after a stop, you should partly engage the clutch before removing your right foot from the brake pedal.

If you are convicted of any kind of traffic violation, in any type of vehicle, you must notify your employer within 30 days. You must also inform your motor vehicle licensing agency of the violation within 30 days if the conviction happened in another jurisdiction. This rule does not apply to parking infractions.

Under slippery conditions, you should drive slowly and smoothly. Make turns as gently as possible and do not pass other vehicles unless you have to.

It is important to observe other drivers' actions and identify clues that a person could be driving impaired. Drivers who have had too much to drink, are sleepy, are on drugs, or are ill can present hazards to other drivers. One sign that a driver may be impaired is that they stop in inappropriate places, such as at green traffic lights.

Drowsy driving is most common during the night because people are naturally prone to be less alert in the hours during which they are normally asleep. If you must drive at night, take every precaution to prevent fatigued driving.

Rough acceleration can cause mechanical damage, so be sure to accelerate smoothly and gradually.

Compressed air in an air brake system usually contains a certain amount of water and compressor oil. The water and oil can damage the brakes if left to accumulate in the system. Tanks must be drained regularly to remove this build-up.

In heavy traffic, it is safest to travel at the same speed as other vehicles. If two vehicles continue to drive in the same direction at the same speed, they cannot hit each other.

Most cases of hydraulic brake failure come from one of two causes. The brakes may fail due to a loss of hydraulic pressure or due to overuse on long hills, causing the brakes to fade.

If your vehicle has air brakes, the air compressor drive belt should be checked before each drive. Check the tightness of the belt and verify that it is in good condition.

Be sure that you are able to accelerate without first rolling back. Rolling backwards may cause you to collide with a vehicle or other obstacle behind your truck.
