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.

It is essential to the safe operation of a CMV that cargo be properly loaded. Improper loading can affect handling and damage the vehicle. Additionally, improperly loaded materials can cause injury or death by falling off of the vehicle.

To avoid a loss of control, you should accelerate slowly when driving in poor-traction conditions, such as rain or snow.

During a trip, you should regularly check the gauge and instrument panels, mirrors, tires, cargo, and lights for signs of trouble.

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

In some vehicles, it may be necessary to leave the engine running when checking the automatic transmission fluid level.

Almost any foreign object on the road poses some potential danger. For example, even something as seemingly harmless as a cardboard box could contain a hard or heavy object that could damage your vehicle.

You should avoid refueling a bus while passengers are on board, unless absolutely unavoidable. In particular, you should never refuel a bus with passengers on board while inside a closed building.

Smoking, eating, or drinking are distracting activities and should be avoided while you are driving. Instead, plan ahead and allow yourself time to stop to eat when making a lengthy trip.

Always drive with caution through work zones. You should make a particular point of reducing your speed when workers are on or near the roadway.

If you must drive in reverse, you should first walk around your vehicle to look at the path of travel and check for obstacles. Because mirrors have blind spots, you cannot rely exclusively on them. It is recommended to use a helper whenever possible.

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).

You should be cautious when you are near people who are not paying attention to the road. Drivers and pedestrians who are talking to someone may be distracted by the conversation and not fully paying attention to the road. Workers on or near the road may not be paying attention to traffic because they are focused on their work, and can themselves also be a distraction to drivers.

When inspecting the interior of a bus, you must make sure everything is safe and in proper working condition. Make sure all signaling devices, such as bathroom emergency buzzers, are in proper working order.

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.

After starting a vehicle's engine, the warning lights and buzzers should turn on, then quickly turn off.

When inspecting the engine compartment, you should check the oil level, coolant level, and windshield washer fluid level, among other things.

When inspecting your vehicle, you should verify that the safety belt is securely mounted, adjusts, latches properly, and is not ripped or frayed.

When checking the tires as part of a pre-trip inspection, make sure the tires have sufficient tread. There should be at least 4/32 of an inch of tread in every major groove of the front tires, and at least 2/32 of an inch of tread depth on the other tires. Tire sizes should not be mismatched.

If you begin to feel tired while driving, the only safe action to take is to stop and get some sleep. Trying to fight the fatigue and press on is very dangerous and can result in a fatal crash. You should not rely on artificial stimulants; these may help keep you awake a while longer, but they won't make you more alert.
