Illinois CDL DMV Knowledge Test Class A 1

Focusing on your mirrors for too long can be dangerous because you will have traveled a substantial distance without looking at the road ahead.

A pre-trip inspection should be completed in the same way before every drive. Consistency will help you learn all of the proper steps and decrease the likelihood that you will forget to check something.

If you encounter a distracted driver, make sure to give them plenty of room. Be very careful if you pass their vehicle because the driver may be unaware of your presence and drift into your lane.

A low air pressure warning signal is required in vehicles with air brakes. The warning light is usually red and may be accompanied by a buzzer.

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

If your vehicle gets stuck on railroad tracks, immediately exit the vehicle and get away from the tracks. Check signs or signal housing at the crossing for emergency contact information. Call the emergency contact or call 911.

During the vehicle inspection test, you must be able to indicate where the oil dipstick is located; show that the oil level is within a safe operating range; and show that the oil level is above the refill mark.

If your hydraulic bakes fail, shifting into a lower gear can help slow your vehicle down.

The liver removes alcohol from the body at a fixed rate that cannot be increased through tricks like drinking coffee or taking a cold shower. The only way to sober up after drinking is to wait for the alcohol to be removed from your system.

When performing a static leakage test on a double combination vehicle with air brakes, the leakage rate should be no more than 3 psi in one minute. If air leaks from the air brake system at a quicker rate, the vehicle should not be driven because something likely needs to be repaired.

In an air brake system, the application pressure gauge shows how much air pressure is being applied to the brakes. Not all vehicles with an air brake system have this gauge.

Livestock being transported as cargo can move around and shift their weight in transit, which can result in unsafe handling.

An applicant who fails any particular CDL test three times must wait 30 days from the date of the third failed test before taking that same test again.

When inspecting an exhaust system, you should verify that parts of the system are not loose, broken, or missing. The system's parts must be properly mounted and should not be rubbing against moving parts of the vehicle.

To prevent rolling backward when starting from a stop, you should partly engage the clutch before removing your foot from the brake. Apply the parking brake whenever necessary to prevent your vehicle from rolling back.

On newer vehicles with air brakes, the parking brake is controlled by a yellow, diamond-shaped knob. The knob is pulled out to set the brakes, and pushed in to release them.

If you are being followed too closely, you should increase your following distance, avoid making quick moves, and avoid relying on tricks (such as flashing your lights) to help other drivers pass. Speeding up may only increase the danger by causing the tailgater to continue tailgating you at a higher speed.

If you experience a loss of hydraulic pressure in your brakes, you should downshift, pump the brakes, and use the parking brake. Seek an escape route, such as an escape ramp, open field, or side street.

During the on-road driving skills test, make sure you do not put your vehicle over curbs, sidewalks, or lane markings. Stop behind stop lines, crosswalks, or stop signs. On multiple-lane roads, complete turns in the proper lane. Always move to or remain in the rightmost lane, unless the lane is blocked.

If confronted by an aggressive driver, the most important thing for you to do is get out of their way. Avoid making eye contact, do not challenge them by increasing your speed, and do not let yourself be provoked by any angry gestures they direct toward you.

It is a driver's responsibility to inspect their cargo; recognize overloading or poorly balanced weight; know that the cargo is properly secured and not obscuring their view; and know that the cargo does not restrict access to emergency equipment. The driver is always responsible for their cargo, even if they were not the one who initially loaded and secured the cargo.

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.

Because air expands when hot, tire pressure increases as temperatures increase. This can sometimes result in tire failure. Consistently check your tire pressure when making a trip in hot weather.

An Anti-Lock Braking System (ABS) helps prevent wheel lockup during hard braking. While it provides better control, it does not necessarily shorten a vehicle's stopping distance.

You can build up a "debt" of sleep if you do not sleep for adequate amounts of time. You can only catch up on the time that you "owe" by getting more sleep.

You should never exceed the speed shown on a "Maximum Safe Speed" sign.

The suspension system keeps a vehicle's axles in place. Damaged suspension parts, such as leaking shock absorbers, may be potentially dangerous defects on a vehicle.

If at least one-fourth of the leaves in a leaf spring are missing, the vehicle will be put out-of-service until the defect is fixed.

To remain aware of hazards behind your vehicle when backing, you should frequently check your mirrors on both sides of the vehicle. Have a helper watch your blind spots whenever possible.

To be certain that others are aware of your intentions, always signal whenever you plan to turn or change lanes. You should signal well in advance of a turn; signal continuously throughout the turn; and make sure to cancel the signal when you are finished turning.

The three main factors that determine a person's blood alcohol concentration (BAC) are the amount of alcohol consumed, how quickly the alcohol is consumed, and the person's weight.

If cargo is covered, the cover should not flap in the wind in transit. The cover could tear loose, uncovering the cargo while potentially blocking your view or the view of others.

After an engine is started, the warning lights and buzzers for oil, coolant, charging circuits, and the Anti-Lock Braking System (ABS) should go out right away.

After an accident, spilled fuel and improper use of flares can result in a fire.

When driving, texting is a particularly dangerous distraction because it distracts a driver both mentally and physically.
