Georgia CDL General Knowledge Test (GA) 5

Correct answer: C – Monitoring the gauges for abnormal readings

Drivers should watch the vehicle’s gauges for signs of trouble throughout a trip. They should also look, listen, smell, and feel for conditions that may indicate a defect. At stops, critical items such as tires, brakes, lights, trailer connections, coupling devices, and cargo securement should be checked.

Correct answer: A – True

Cold medicines and other over-the-counter drugs may cause drowsiness or affect the ability to operate a CMV safely. Drivers should follow warning labels and medical instructions. A prescribed substance is permitted only when the treating medical practitioner has advised that it will not interfere with the driver’s ability to operate a CMV safely.

Correct answer: D – All of the above

Georgia’s CDL manual describes placards as diamond-shaped warning signs displayed on the front, rear, and both sides of a placarded vehicle. Federal rules require a placard to be clearly visible from the direction it faces and kept clear of equipment or attachments that could obstruct it. Each of the listed statements is correct.

Correct answer: A – You can usually steer around an obstacle more quickly than you can stop

When there is not enough room to stop, steering away from the hazard may prevent a collision because a vehicle can usually turn more quickly than it can stop. Keep both hands firmly on the steering wheel and avoid turning more sharply than necessary. Top-heavy vehicles and tractors pulling multiple trailers have an increased rollover risk during sudden steering.

Correct answer: D – Class 8 corrosive material

Battery fluid is listed as an example of a Class 8 corrosive material. Corrosive materials can damage living tissue or other cargo and equipment. When charged storage batteries are transported, they must be kept upright and loaded to prevent leakage, falling cargo, and short circuits.

Correct answer: B – The coolant-temperature gauge

After starting a cold engine, the coolant-temperature gauge should begin a gradual rise toward the normal operating range. Oil pressure should reach a normal reading within seconds rather than several minutes. During operation, an excessive coolant-temperature reading can indicate a condition that may lead to engine failure or fire.
