Oregon CDL DMV Knowledge Test Class A 2

You must sign a vehicle inspection report only if defects were noted and either certified to have been repaired or certified as not needing to be repaired.

When driving, you should always scan the road for potential hazards. Formulate plans for how to deal with the hazards if they develop into emergencies.

When driving, you should frequently check the mirrors on both sides of your vehicle.

Driving in fog is always dangerous and should be avoided entirely if at all possible. If you must drive in fog, be sure to turn on your low beam headlights and fog lights, even during the daytime.

If you must come to a stop before making a turn during the driving skills test, you should come to a smooth stop behind any stop line, crosswalk, or stop sign. Keep your front wheels aimed straight ahead and do not let your vehicle roll. If stopping behind another vehicle, stop where you are still able to see the rear tires of the vehicle ahead of you.

If you begin to feel drowsy while driving, the best thing to do is to stop and get some sleep. A driver trying to push on and finish a trip while fatigued is a major cause of fatal accidents.

If you are not sure which kind of extinguisher should be used on a fire in your vehicle, particularly a hazardous materials fire, you should wait for the firefighters to arrive and allow them to extinguish it.

A driver uses a look when they open their door, leave their seated position, and walk to the back of the vehicle to check its position. During the straight line backing exercise, a driver may not exceed one look. During any other exercise, a driver may not exceed two looks.

Federal Motor Carrier Safety Regulations (FMCSR) require carriers to affix the USDOT number to both sides of each CMV in their fleet.

Parking brakes should always be checked before driving as a part of your pre-trip inspection. If the parking brakes do not hold, the vehicle is faulty and should be fixed.

Remaining in neutral for too long when shifting gears may make it difficult to put the vehicle into the next gear.

If you aren't sure that you have space for your vehicle to safely fit underneath an overhead object, slow down and seek an alternate route if possible.

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.

An Individual Vehicle Distance Record (IVDR) must include information about the distance traveled by a vehicle and the amount of fuel purchased. The required distance information includes the origin and destination points of the trip and the Vehicle Identification Number.

Use your low beam headlights when traveling near other drivers at times when it is difficult to see, such as at dawn, at dusk, or in poor weather conditions. Using the high beam setting under certain conditions could make it difficult for other drivers to see.

You will be denied a hazardous materials endorsement, or lose an existing endorsement, if you renounce your U.S. citizenship; are not a lawful permanent U.S. resident; are wanted for, indicted for, or convicted of certain felonies; are judged mentally defective or are committed to a mental institution; or are deemed by the Transportation Security Administration (TSA) to pose a security threat.

When inspecting a vehicle, you should verify that your dual tires do not come into contact with one another, or with any other part of the vehicle.

In an air brake system, the air storage tanks are equipped with drains to allow water and compressor oil to be removed. The water and oil can damage the brakes if left to accumulate in the system.

If you lose pressure in a hydraulic brake system, one appropriate response is to shift down into a lower gear. This will help slow the vehicle.

When asked to make a turn during the on-road driving test, you must check traffic in all directions and use your turn signal.

If you drive over a bridge during the on-road driving skills test, the examiner may ask you afterwards to recall the bridge's posted weight limit.

Always decrease your speed when traveling through a construction area. Slow down even further if there are workers on or near the roadway.

An air compressor governor will stop the compressor from pumping air once the air tanks are at an air pressure level of 125 psi. This air pressure level is referred to as the "cut-out" level.

Front-end header boards, also known as "headache racks," protect the driver from cargo moving in the event of a crash or emergency stop.

Retarders are mechanisms in some vehicles that help slow a vehicle and reduce the need for braking. However, using a retarder may cause wheels to skid when they have poor traction. Turn off retarders when traveling under wet, snowy, or icy conditions.

For safety, you must wear your seat belt at all times while operating a CMV.

The purpose of an Anti-Lock Braking System (ABS) is to prevent a vehicle's wheels from locking up when the driver brakes hard on a slippery surface.

While driving a CMV, you may not make voice calls if you need to hold your phone or press more than one button to do so. Additionally, you may not send or read text messages while driving.

Alcohol impairment begins long before the legal limit is reached. A 200-pound person will reach a blood alcohol concentration (BAC) of 0.02 percent after a single drink.

Drivers with blocked vision may pose hazards to others on the road. Examples of such drivers include those who haven't scraped ice off of their windshields; those driving vehicles loaded with large items blocking the windows; and those who are driving rental trucks without being used to the limited rear visibility of a truck.

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.

Truck tractors with air brakes built on or after March 1, 1997 must be equipped with an Anti-Lock Braking System (ABS).

Your vehicle's engine may need to be running in order for you to check the level of its automatic transmission fluid.

In an air brake system, air tanks have drains to remove accumulations of water and compressor oil. Allowing water and oil to accumulate in the system could cause damage to the brakes. Manually operated drains should be used daily.

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