When making mirror checks, you should look at the mirrors fairly quickly. If you spend too much time looking in a mirror, you may travel a substantial distance down the road without seeing what is coming up ahead.

Your vehicle pulling to one side or the other while you are braking can indicate trouble with the brakes.

Be careful around pedestrians, joggers, and cyclists who are wearing headphones. They may be unable to hear your vehicle approaching and may do dangerous things because they do not know you are there.

Bridges tend to freeze before other parts of the roadway. Be particularly careful on bridges when temperatures are close to the freezing point.

All commercial motor vehicles are required to be equipped with the proper emergency equipment. This may include spare electrical fuses; three red reflective triangles, six fuses, or three liquid burning flares; and at least one properly charged and rated fire extinguisher.

Federal and state laws require drivers to inspect their vehicles before every trip, regardless of length.

If you choose to use a mobile phone while operating a CMV, you may only use a hands-free mobile phone that is located close to you. However, even a hands-free mobile phone can be a dangerous distraction while driving. Make sure you are aware of all cell phone laws in the state in which you are driving.

A dual air brake system is made up of two separate air brake systems. If there is an air leak in one system, it may not affect the other.

All commercial motor vehicles are required to be equipped with the proper emergency equipment. This may include spare electrical fuses; three red reflective triangles, six fuses, or three liquid burning flares; and at least one properly charged and rated fire extinguisher.

When inspecting your brakes, you should check for cracked drums; shoes or pads covered in oil, grease, or brake fluid; and shoes that are missing, broken, or worn dangerously thin.

Controlled braking is the method of applying a vehicle's brakes as hard as possible without locking the wheels. A driver should keep steering wheel movements very small if braking while using this method.

The total stopping distance for vehicles equipped with air brakes is made up of four factors: perception distance, reaction distance, brake lag distance, and braking distance. When braking at a speed of 55 mph while driving on dry pavement, the brake lag can add around 32 feet to the vehicle's total stopping distance.

During the vehicle inspection test, you will be required to do a complete inspection of your vehicle. During this inspection, you must explain to the examiner what you are inspecting and why you are inspecting those items.

Air brakes are really three different braking systems: the service brake, the parking brake, and the emergency brake. Emergency and parking brakes are applied with mechanical force.

At speeds below 40 mph, you should allow at least one second of following distance for every 10 feet of your vehicle. Follow the same formula when traveling at faster speeds, then add one additional second to your following distance. Remember that larger vehicles require more space to stop than smaller vehicles.

When driving at dawn, at dusk, or in inclement weather, you should use your headlights on their low beam setting to increase your visibility.

Most newer heavy-duty vehicles use dual air brake systems. A dual air brake system has two separate air brake systems which use a single set of brake controls.

You should always exercise caution when driving near a stopped bus. There could be passengers in the vicinity and the bus may either prevent them from seeing you or you from seeing them.

Warning placards are required to be used any time a vehicle is carrying designated types and amounts of hazardous materials. A placarded vehicle must display placards on all four of its sides.

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.
