Kansas CDL Permit Test - Passenger

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.

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.

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 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.

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.

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."

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.
