It is important to inspect your tires before every drive. Rust around wheel nuts may indicate that they are loose.

While regular mirror checks should always be part of your driving routine, you should make a particular point of checking the mirrors when changing lanes, turning, merging, or making tight maneuvers.

If you double your speed, your braking distance will become four times longer. Similarly, the impact your vehicle would have in the case of a collision will also multiply by four.

The driver of a vehicle is responsible for the safe transport of its cargo, regardless of who loaded the vehicle.

Before starting down a hill, you should shift into a lower gear. This will help get your vehicle to a speed that you can control without having to use your brakes too much.

Black ice is a layer of ice that is thin and clear enough for the road to be visible through it. This makes the road look as if it is merely wet.

To reduce the risk of distraction, do not engage in complex or emotionally intense conversations while driving. Pre-programming radio stations before your trip and avoiding eating, drinking, or smoking while at the wheel can also help you avoid becoming distracted while driving. Remember that mental distractions that take your attention away from the task of driving can be just as dangerous as physical distractions.

Make a point of checking your mirrors often when making tight maneuvers.

Increasing your vehicle's speed will increase your vehicle's striking power and braking distance. Doubling your vehicle's speed from 20 to 40 mph will multiply its braking distance by four.

A bus may never carry labeled radioactive materials in the space occupied by people. Small arms ammunition labeled ORM-D and emergency hospital supplies may be carried.

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.

When using a fire extinguisher, you should stand as far away from the fire as possible. Aim the extinguisher at the base of the fire, not at the flames. If you are not sure which kind of extinguisher should be used on a fire, particularly a hazardous materials fire, you should wait for the firefighters to arrive and allow them to extinguish it.

Factors that can affect stopping distance include the vehicle's speed, its weight, and the traction provided by the road surface.

Air expands as it gets warmer, so the air pressure in your tires could reach dangerously high levels while being driven in very hot weather. If this happens, stop and let your tires cool. Do not let air out of the tires, as this could result in the pressure dropping to an unsafe level once they cool down.

The heavier a vehicle is, the more the brakes will need to work to bring the vehicle to a complete stop.

You should start and stop as smoothly as possible to help prevent passenger injury. After passengers have boarded your bus at a stop, you should allow them time to be seated or to brace themselves before you begin driving.

Hydroplaning is an effect in which a vehicle's tires lose traction with the surface of the road and instead glide along a layer of water. There does not have to be a large amount of water on the road for this to occur.

Hazardous materials must be marked with the name of the material, the identification number, and the appropriate hazard label. Do not transport a hazardous material unless you are positive that it is permitted.

When backing with a trailer, begin by turning the steering wheel in the direction opposite of the turn. Once the trailer starts to turn, reverse the direction of the steering wheel to follow the trailer.

Ice becomes wet when the weather is just warm enough to melt the ice slightly. Wet ice is much more slippery than ice that is not wet.
