Kansas CDL DMV Endorsement Passenger 2

In the event of tire failure, hold the steering wheel firmly. Stay off the brakes and let the vehicle slow down on its own. Once the vehicle has slowed considerably, you should brake very gently, pull off the road, and stop.

The purpose of an Anti-Lock Braking System (ABS) is to prevent a vehicle's wheels from locking up when the driver brakes hard on a slippery surface.

Always change lanes slowly and smoothly. If you did not see drivers who are already using the lane you wish to occupy, this will give them a chance to get out of your way or honk their horns to alert you. Always signal before changing lanes.

In an air brake system, a low pressure warning signal should activate if the pressure in the air tanks falls to a level below 60 psi. This signal may be in the form of a warning light or a wig wag.

When approaching a railroad crossing while driving a bus, you must stop between 15 and 50 feet from the nearest track to look and listen for any approaching trains. Only proceed once you are certain that there are no approaching trains. You do not need to stop at streetcar crossings; if a police officer or flagger is directing traffic; if there is a green traffic signal at the crossing; or at crossings marked "exempt" or "abandoned."

Placards must be placed on the outside of vehicles carrying hazardous materials. They identify the specific class or classes of materials being carried and warn others of relevant hazards.

When inspecting the interior of a bus, you must make sure everything is safe and in proper working condition. Take the time to ensure every handhold and railing is securely in place and safe to use.

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

If you observe a crash involving an aggressive driver, you should stop a safe distance from the crash scene, wait for police to arrive, and inform them of the aggressive behavior you witnessed.

When inspecting a trailer during a vehicle inspection test, ensure that its landing gear has no missing parts and that it is fully raised. The crank handle should be secure and the support frame should not be damaged.

Mirrors should be checked prior to the beginning of a trip. On a vehicle with a trailer, mirror adjustment can only be checked accurately if the connected trailer is straight.

You should never rely only on warning signals to alert you to an approaching train. Never try to race a train to a crossing. If there are multiple tracks at a crossing, be sure to check all tracks in both directions before starting to cross.

Stopping is not always the safest option when responding to an emergency while driving. It is usually safer to steer out of the way when attempting to avoid a crash.

You may be able to tell that another driver is distracted if you can see them drifting within a lane or across lane dividers; traveling at inconsistent speeds; being preoccupied with a cell phone, a map, food, or other items; or engaging in conversation with passengers.

A one-way check valve is required to be between an air compressor and the first main reservoir. This valve prevents air from escaping the system if the air compressor develops a leak.

If you begin to feel sleepy while driving, the only safe response is to stop driving and get some sleep. Attempting to fight off exhaustion is dangerous and a major cause of fatal crashes. Stimulants are not a safe solution because they may help keep you awake but will not make you more alert. Once stimulants wear off, you will be even more tired than you were originally.

If you aren't sure that you have space for your vehicle to safely fit underneath an overhead object, slow down and seek an alternate route if possible.

If you experience a loss of hydraulic pressure in your brakes, you should downshift, pump the brakes, and use the parking brake. Seek an escape route, such as an escape ramp, open field, or side street.

If you use a helper while backing your vehicle, they should stand near the back of the vehicle in a place where they are visible to you. Before backing, work out a set of hand signals that both you and your helper understand. Agree on a signal for "stop."

Focusing on your mirrors for too long can be dangerous because you will have traveled a substantial distance without looking at the road ahead.
