A vehicle that is equipped with air brakes must also be equipped with a supply pressure gauge. This gauge tells the driver how much air pressure is in each of the vehicle's air tanks.

To reduce the risk of developing aggressive driving behavior, you should take measures to manage your stress. One strategy to do this is to simply take a deep breath and accept your circumstances if you realize you will be late to your destination.

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.

It is important that vehicles are not top-heavy, if at all possible. A top-heavy vehicle is at an increased risk of rollover. Place the heaviest pieces of cargo underneath lighter pieces of cargo.

The purpose of an Anti-Lock Braking System (ABS) is to help prevent wheel lockup and help a driver maintain control of their vehicle when braking on a slippery surface.

Tire load is the maximum weight a tire can safely carry at a given pressure. This rating is stated on the side of each tire.

Stay as far away from a fire as possible and aim your fire extinguisher at the source or base of the fire, not at the flames. It may be appropriate to extinguish certain fires with water. If you are unsure of how to treat a specific fire, you should wait for trained firefighters to arrive.

Blocking and bracing are used to prevent cargo from shifting in transit.

Because air pressure increases with temperature, you should pay special attention to the tire mounting and pressure when traveling in hot weather.

Backing is always dangerous and should be avoided whenever possible. When parking, look to park in a space that will allow you to pull forward when exiting.

Transporting cargo that is loaded with a high center of gravity increases the risk that the transporting vehicle will tip over. Cargo should be loaded with a safe weight distribution.

After an engine is started, the coolant temperature should rise gradually to a normal operating range.

During a pre-trip inspection, you should check for emergency equipment, including spare electrical fuses; three red reflective triangles, six fuses, or three liquid burning flares; and at least one properly charged and rated fire extinguisher.

Your vehicle's horn is a tool to warn others of your presence. Because the horn may create danger by startling other drivers, you should use it only if necessary.

If you must use a mobile phone while driving, it must be in close proximity to you and easily reachable while you are securely fastened into your seat. It is dangerous and non-compliant to unsafely reach for a mobile phone, even if you plan to use a hands-free feature when speaking on the phone.

Many large CMVs are equipped with air brakes. An air braking system uses compressed air to operate.

You should cover your cargo to protect people from the cargo if it spills, as well as to protect the cargo from the weather.
