Hawaii CDL Permit Test - Knowledge Test Class B

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.

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.

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.

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 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.

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

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.
