Minnesota CDL Permit Test - Bus

If you must back up, it is safest to back toward the driver's side of the vehicle. This way, as the driver, you will have the best possible view of your path of travel.

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.

When checking the exhaust system, you should verify that no parts of the system are loose, broken, or missing.

There may be a delay of a few seconds between the sound of a tire failing and the time that the vehicle is affected by the tire failure. Because of the short delay, a driver may initially believe that the sound came from another vehicle.

Defects in an exhaust system are very dangerous because they can cause poisonous fumes to enter the cab or sleeper berth.

After a tire has been changed, you should stop a short while later to re-check the tightness of the lug nuts.

Before starting down a hill, decelerate and shift down into a gear that will allow you to control your vehicle without braking too hard. Using too much brake when driving downhill can cause the brakes to overheat, reducing the braking power.
