13 . The parking brake in a newer vehicle is applied by:
In newer vehicles with air brakes, the parking brake is controlled by a yellow, diamond-shaped knob. The driver should pull the knob outward to apply the parking brakes and push the knob inward to release them.
14 . Using an Anti-Lock Braking System (ABS):
An Anti-Lock Braking System (ABS) helps to provide additional control during hard braking, but does not necessarily shorten a vehicle's stopping distance.
15 . While driving, ____ generally holds spring brakes in place.
While driving, spring brakes are generally held in place by air pressure. If the air pressure gets low enough, the springs will activate the brakes.
16 . In a dual air brake system, if one air system is very low on pressure:
In a dual air brake system, either the front or rear brakes will not be fully operable if one of the air systems gets too low on pressure. If the air pressure in either tank gets too low while you are driving, you should exit the road and park as soon as possible.
17 . The leakage rate for a triple combination vehicle with air brakes should be no more than ____ in one minute during a static leakage test.
When performing a static leakage test on a triple combination vehicle with air brakes, the leakage rate should be no more than 5 psi in one minute. If the air leaks from the air brake system at a quicker rate, the vehicle should not be driven because something likely needs to be repaired.
18 . What can happen if the air pressure gets too low in an air brake system?
Pressing and releasing the brake pedal unnecessarily can let air out of the braking system faster than the compressor can replace it. Air brakes may cease to work effectively if the pressure becomes too low.

To secure a CDL bus endorsement in Alaska, you first need to possess a valid Commercial Driver's License (CDL). Then, you must pass the Passenger Vehicles endorsement test. This test covers topics like vehicle inspection, loading, and on-road driving. After passing the test, you'll receive your bus endorsement. Check with the Alaska DMV for specific requirements and fees.
To obtain a CDL Bus license in Alaska, you must first hold a valid Commercial Learner's Permit (CLP) for at least 14 days. You'll then need to pass the General Knowledge test, Passenger Transport test, and a skills test in a vehicle similar to the one you'll be driving. Also, you must pass a DOT physical examination and submit a medical certification.
While Alaska does not explicitly require specific training for a CDL Bus endorsement, it's beneficial to have professional training. This can help you pass the required knowledge and skills tests. Experience driving similar vehicles can also be beneficial. Moreover, applicants must pass a physical examination and meet specific vision requirements.
CDL Bus licenses in Alaska fall under Class B or Class C. Class B is for vehicles designed to transport 24 passengers or more, including the driver. Class C is for vehicles designed to carry 16 to 23 passengers, including the driver. Each class requires passing specific knowledge and skills tests. The type of vehicle you plan to drive determines the class of license needed.
No, you cannot use your personal vehicle for the CDL Bus driving test. The vehicle used for testing must match the class of vehicle you plan to drive with your CDL. For a bus endorsement, this means you must test in a bus of the appropriate size. This ensures you can safely operate a similar vehicle under typical working conditions.
During the CDL Bus driving test, your ability to safely operate a bus is evaluated. The test includes pre-trip vehicle inspection, basic vehicle control, and on-road driving. You'll be asked to perform maneuvers such as turning, merging, backing up, and navigating intersections. You'll also be evaluated on bus-specific skills like loading/unloading passengers, operating special features, and responding to emergency situations.

The exam includes vision and hearing tests, blood pressure checks, and an assessment of physical abilities necessary for commercial bus driving.

The endorsement is necessary because it validates that the driver has the necessary skills and knowledge to safely operate a passenger vehicle. Driving a bus without the proper endorsement could result in hefty fines, loss of your CDL, or even imprisonment.
You can add a CDL Bus endorsement to your existing commercial driver's license. However, you're required to pass a written passenger vehicles test and a skills test in the type of vehicle you will be driving. You don't need to apply for a new license, but you must meet these additional requirements.
