Arizona CDL DMV Knowledge Test Class A 2

If you see a distracted driver, give them plenty of space and maintain a safe following distance.

Completing the steps of a vehicle inspection in the same order before every trip aids in learning what the proper steps are. Additionally, you be less likely to forget a step when going through the checklist in a prescribed order.

If you are asked to complete an offset back/left parking maneuver, you should first pull straight forward, then back up to the left. Your vehicle must be parked completely within the boundaries of the parking space.

A vehicle inspection should be completed in the same order every time. This will make it easier for you to learn all of the steps and will make it less likely that you will forget to check something.

You should stay in the right lane of a multilane road if your vehicle is being slowed down by a heavy load. Allow other vehicles to pass your truck using the left lane.

On- and off-ramps can be dangerous when driving a truck. Remember that posted speed limits for ramps may be safe for cars but too fast for trucks.

If you begin to feel tired while driving, you should stop to get some sleep. Trying to push on to reach your destination while tired is dangerous. You should not rely on caffeine to keep you awake.

Warning placards are required to be used any time a vehicle is carrying designated types and amounts of hazardous materials. A placarded vehicle must display placards on all four of its sides.

When approaching your vehicle, you should check under the vehicle for fresh oil, coolant, grease, or fuel leaks. Spotting any of these before a trip is a cause for concern.

When inspecting a vehicle that is equipped with power steering, check the hoses, pumps, and fluid level. In particular, you should look for leaks in the hoses.

When braking a vehicle equipped with an Anti-Lock Braking System (ABS), you should not brake any differently than you would if driving a vehicle with a different braking system.

You should always slow down to a safe speed and shift into a lower gear before entering a curve.

Compressed air in an air brake system usually has a certain amount of water and oil in it. This can harm the system if allowed to accumulate. Air tanks have drain valves to aid in removing water and oil from the compressed air.

A skid caused by over-acceleration can be resolved simply by removing your foot from the accelerator. Skids of this nature happen most frequently on surfaces covered in snow or ice.

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.

Wheels or rims that have had welding repairs should never be used.

Passing parked delivery or postal trucks can be dangerous because the driver may be in a hurry and pull into traffic without warning, or may they suddenly step out of the vehicle without checking for other traffic.

Front wheel braking is effective under all road conditions. It is unlikely that you will experience a front wheel skid, even on ice.

If the low air pressure warning signal comes on while you are driving a vehicle with air brakes, you should immediately bring the vehicle to a safe stop while you are still able to control the brakes. Inspect and repair the brakes as soon as possible.

Be cautious when driving near people who are working on a disabled vehicle on the side of the road. They may be focused on the repair and not paying attention to nearby traffic.

Missing clamps, spacers, studs, or lugs are dangerous, as are mismatched, bent, or cracked lock rings. Be sure your tires and rims are in good condition before operating your commercial motor vehicle.

Be sure to thoroughly inspect your tires before a trip. Tire sizes should not be mismatched, and tires should not be cut, cracked, or otherwise damaged in any way.

Before beginning a trip, it is important to check the brake drums during your walk-around inspection. It is unsafe to drive if any brake drum has a crack more than one half of the width of the friction area.

If you are not sure which method to use when putting out a fire, do not attempt to extinguish the fire on your own. Instead, wait for firefighters to arrive and let them handle it. This is especially true if you are experiencing a hazardous materials fire.

In the event of a crash, a safety belt keeps the driver of a commercial motor vehicle securely positioned behind the steering wheel. This both protects the driver from injury and makes it easier for them to maintain control of the vehicle.

The Anti-Lock Braking System (ABS) indicator light should come on after an engine is started. The light will then turn off. If the light remains on, the ABS it not working properly.

The doors of a trailer should be not be opened in the event of a cargo fire, especially if the cargo includes hazardous materials. Opening trailer doors would increase the fire's oxygen supply, potentially causing the fire to increase in size.

When asked to make a lane change during the on-road driving test, you should make the proper traffic checks, use your turn signal, and smoothly change lanes when it is safe to do so.

When driving at dawn, at dusk, or in inclement weather, you should use your headlights on their low beam setting to increase your visibility.

Tire load is defined as the maximum safe weight that a tire can carry at a specified pressure.

If you must drive so slowly that you will impede the flow of traffic, you should turn on your four-way flashers to alert drivers behind you (as long as local laws allow the use of flashers).

After a vehicle is started, the warning lights and buzzers should go out after a few seconds. If the warning signals do not turn off, there may be something wrong with the vehicle.

There should be at least 4/32 of an inch of tread depth in every major groove on front tires and 2/32 of an inch on other tires. Valve stems should not be cut or cracked. Tire sizes should not be mismatched.

You may be able to tell that another driver is distracted if you can see them drifting within a lane or across lane dividers; traveling at inconsistent speeds; being preoccupied with a cell phone, a map, food, or other items; or engaging in conversation with passengers.

The air compressor of an air brake system is connected to the engine through gears or a v-belt. The compressor may be air-cooled or cooled by the engine cooling system.
