If you must stop on the side of the road, you should turn on your emergency flashers and place the appropriate warning signals to warn other drivers.

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.

The function of an Anti-Lock Braking System (ABS) is to help prevent wheel lockup during hard braking. With ABS equipped on your vehicle, you should drive and brake in the same manner that you would without it.

Bus passengers should not be allowed to leave baggage in any doorway or aisle. Baggage and freight must be secured in a manner that will prevent damage, allow the driver to move freely and easily, allow riders to exit by any window or door in an emergency, and protect riders from injury if the items fall or shift.

Check your tires regularly when looking in your mirrors. This helps ensure that you will notice a tire fire, if one should happen. Tire fires may occur when a tire is under-inflated, if dual tires are touching, or if the tires are otherwise overheated.

Skids happen when tires' traction with the road surface decreases. This can be caused by over-braking, over-accelerating, over-steering, and driving too fast.

Cargo must be properly secured to prevent it from moving in transit. Loose cargo can be dangerous to the driver operating the CMV, as well as to other road users.

Though there are some exceptions to this rule, most hazardous materials are not permitted to be transported by bus. The safety of your passengers is your responsibility.

Backing a truck is always dangerous because the driver may not be able to see everything behind them. CMV operators should avoid backing whenever possible.

For some vehicles, you may need to leave the engine running to be able to check its automatic transmission fluid level.

Stopping is not always the best way to avoid a hazard. If there is not enough space for you to stop to avoid coming into contact with the hazard, swerving out of the way may be your safest option.

To maintain proper control of your vehicle, the steering wheel should be held firmly with both hands. Your hands should be positioned on opposite sides of the wheel.

If your vehicle begins to hydroplane, do not apply the brakes. Instead, slow down by releasing the accelerator and pushing in the clutch. This will help you to regain traction.

On a steep downgrade, you must use the engine's braking effect as your primary method of speed control. Be sure to decelerate and downshift appropriately before beginning to drive down the hill.

A bus should not be refueled while passengers are on board, unless it is absolutely unavoidable. A bus with passengers on board should never be refueled inside an enclosed building.

Bridges usually freeze before the rest of the road. You should be especially careful when crossing bridges if the temperature is near the freezing point.

When backing a vehicle with a trailer, you must turn the steering wheel in the direction opposite of where you want to go. Once your trailer starts to turn, you should turn the steering wheel the other way to follow the trailer.

While a bus is traveling, passengers may not stand any farther forward than the rear of the driver's seat. To mark this barrier, a bus that is designed to allow passengers to stand must have a two-inch line on the floor (or some other means of showing passengers where they cannot stand). This is known as the standee line.

Distractions that can affect safe driving can be classified as physical (such as reaching for an object), mental (such as talking with passenger), or both (such as talking on a hand-held phone).

Backing is always dangerous because it is impossible to see everything that is behind your vehicle. Only drive in reverse if it is absolutely necessary.
