Bus drivers and passengers should not be permitted to bring common hazardous items, such as gasoline or car batteries, onto a bus.

A disabled bus should not be towed or pushed while passengers are still on board, unless it would be unsafe for the passengers to exit the bus in its current location. If this is the case, the disabled bus should be towed or pushed to the nearest safe location for the passengers to be discharged.

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

In the event of tire failure, hold the steering wheel firmly. Stay off the brakes and let the vehicle slow down on its own. Once the vehicle has slowed considerably, you should brake very gently, pull off the road, and stop. Check your tires after coming to a complete stop.

You should accelerate very gradually when driving under slippery conditions. Using too much power in such conditions may cause you to lose control of your vehicle.

If a drawbridge is controlled by a traffic signal that is displaying a green light, a bus does not need to stop before crossing the bridge. However, a bus driver should always slow down before crossing a drawbridge to make sure that it is safe to proceed.

B and C type fire extinguishers are designed to work on electrical fires. Water should never be used to extinguish an electrical fire because doing so could result in an electrical shock.

A driver is allowed to exit their vehicle to check its position during any basic control skills test exercise. This action is called a "look." During the straight line backing exercise, a driver may not exceed one look. During any other exercise, a driver may not exceed two looks.

Never assume that the posted height on a bridge or other overhead object is correct. Even if it was accurate when posted, things may have changed that affect clearance, either permanently (such as a repaving of the road) or temporarily (such as packed snow on the road).

If making a left turn where there is more than one available turn lane, you should always choose to begin your turn in the rightmost lane. Large vehicles often have to swing right to make left turns. Because of this, it is safer for you to have other left-turning traffic to your left instead of to your right. This will allow you to have the best possible view of other turning vehicles and will lower the risk of your vehicle colliding with them.

Once you have begun to drive after a tire has been changed, you should stop after a short distance to recheck the tightness of the lug nuts.

When checking your vehicle's tires, you should confirm that air pressure is neither too low nor too high; that there is at least 4/32 of an inch of tread depth in every major groove on the front tires; and that radial and bias-ply tires are not used together.

Splitting driving responsibilities with a second driver lowers the chance that either of you will drive while fatigued. You can also reduce the risk of fatigue by avoiding heavy foods and keeping the interior of the cab cool.

Black ice is a thin layer of ice that is clear enough for the road surface to be seen through it. A road covered in black ice may look like it is merely wet. You should be very careful when temperatures are below freezing and the road looks wet.

A steering wheel should have no more than 10 degrees of play. This is equal to about two inches of movement at the rim of a 20-inch wheel. If there is more play than this, it may be difficult to steer.

To correct a drive-wheel braking skid, you should first remove pressure from the brake pedal to allow the locked wheels to begin rolling again. Quickly steer in the direction you want to go, then countersteer to prevent your vehicle from skidding in the opposite direction.

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.

Bus accidents most commonly occur at intersections. Use caution, even if the intersection is controlled by signs or signals.

You should accelerate very gradually when driving under conditions that create poor traction.

When inspecting your tires, verify that there is at least 4/32 of an inch of tread depth in every major groove on the front tires, and tread depth of at least 2/32 of an inch on the other tires. Tires on the same vehicle should all be the same size.
