Hawaii CDL DMV Knowledge Test Class B 2

Always signal continuously through a turn. Do not cancel a signal until the turn is finished.

If your brakes fail on a downgrade, you will have to look outside your vehicle for a way to stop. Using an escape ramp is the safest way to stop your vehicle.

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 control skills test.

If you encounter an aggressive driver, you should not let yourself be provoked by any angry gestures they make toward you. Avoid making eye contact with the other driver and do not try to race them.

To help avoid frustration, which can lead to aggressive driving behavior, you should begin a trip with realistic expectations about your travel time. Plan ahead to allow time for potential traffic delays. Other strategies to help prevent aggressive driving behavior include driving an appropriate speed and keeping a reasonable following distance; avoiding making gestures at other drivers; and keeping your hands on the steering wheel.

Compressed air usually contains a certain amount of moisture and compressor oil, which can build up in the air storage tanks and damage the brake system. The tanks should be drained to clean out these accumulations. On a tank with a manual drain valve, draining should be performed at the end of each day of driving.

Some air brake systems contain an alcohol evaporator. An evaporator introduces alcohol into the system to help inhibit the formation of ice in cold weather.

When inspecting your vehicle's engine, check the belts for tightness and excessive wear. The amount of "give" that is safe for each belt in a given engine will vary, so learn what is appropriate for your vehicle.

Blocking and bracing are used to prevent cargo from shifting in transit. Blocking is used in the front, in the back, and on the sides of a piece of cargo to prevent movement. Bracing prevents movement by reaching from the upper portion of a piece of cargo to the floor and sides of the cargo compartment.

When inspecting a vehicle equipped with power steering, you should inspect the hoses, pumps, and fluid levels. Specifically check the hoses for leaks.

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.

During the on-road driving test, if your route does not include a railroad crossing, the examiner may ask you to explain and demonstrate the necessary procedures at a simulated location.

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

During a pre-trip inspection, be sure to check the mirrors and windshield for dirt and anything else that could interfere with your ability to see. Clean them as necessary.

The risk of hydroplaning begins when water has collected on the surface of a road.

Components of an air brake system include an air compressor, an air compressor governor, air storage tanks, air tank drains, an alcohol evaporator, a safety valve, a brake pedal, foundation brakes, supply pressure gauges, an application pressure gauge, a low air pressure warning signal, a stop light switch, a front brake limiting valve (on some older vehicles), spring brakes, and parking brake controls.

When driving on a wet road surface, the risk of hydroplaning is increased if your tire pressure is too low or your tire tread is too worn. If you begin to hydroplane, release the accelerator and push in the clutch to slow down.

Roads are often especially slippery when it first begins to rain. Rainwater forms a slick film when mixed with oil and grease on the road surface that has not yet washed away.

It is important to inspect your tires before every drive. Rust around wheel nuts may indicate that they are loose.

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.

B:C fire extinguishers are designed to work on electrical fires and burning liquids. Don't pour water on an electrical fire.

Cargo should be inspected before beginning a trip, within the first 50 miles of the trip, and every three hours or 150 miles traveled thereafter. Cargo should be inspected every time the driver stops to take a break. The driver of a truck transporting cargo is responsible for the cargo being safely secured throughout the trip.

When backing, you should pull forward to reposition your vehicle whenever needed. Drift should be corrected immediately by turning the steering wheel in the direction of the drift.

Avoid being an aggressive driver by being realistic about your travel time, making allowance for delays, maintaining reasonable following distances, and not making hand gestures that could anger another driver.

The force of gravity will cause a vehicle's speed to increase when traveling downhill.

When loading cargo, it is important that the weight placed on each axle is neither too little nor too much. Inappropriate loading can interfere with steering, create inadequate wheel traction, or damage the axles.

If you experience tire failure, you may hear the loud "bang" sound of a blowout or feel a heavy thumping or vibration in your vehicle. If steering begins to feel heavy, or if the rear of your vehicle begins to fishtail, you should stop to check your tires.

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.

If confronted by an aggressive driver, it is most important to get out of their way, if possible. Do not make eye contact with the driver, as doing so could provoke them. Do not let them provoke you with their actions.

It is essential that your low pressure warning light functions properly. After allowing the system to charge, you can test the warning signal by rapidly applying and releasing the brake pedal. This will release air from the braking system and the warning signal should come on when pressure drops to a dangerous level.

While regular mirror checks should always be part of your driving routine, you should make a particular point of checking the mirrors when changing lanes, turning, merging, or making tight maneuvers.

Without a working Anti-Lock Braking System (ABS), your vehicle will still have normal brake function. Continue to drive and brake as you normally would and have your ABS serviced as soon as possible.

To avoid hitting vehicles behind you, you must ensure that your vehicle will not roll backward when you start moving forward from a stopped position.

Distractions that can affect safe driving can be classified as physical (such as reaching for an object), mental (such as talking with passenger), or both (such as talking on a hand-held phone).

Because you can't see everything behind you, backing is always dangerous and should be avoided whenever possible. Choose parking spaces from which you can pull forward when you leave.
