36 . When backing, it is best to:
Use a helper, if possible.
If you must drive in reverse, you should back up slowly and use the mirrors on both sides of your vehicle. Use a helper to monitor your blind spots whenever possible. You and the helper should agree on a signal for "stop."
37 . How can a person check for a leak in hydraulic brakes?
Remove the rear wheel and listen for a noise when the brake pedal is depressed.
Check hydraulic brakes by pumping the brake pedal three times before applying firm pressure to the pedal for five seconds. The pedal should not move. If it does, there may be a leak or some other problem in the braking system.
38 . If a vehicle is found to be over-length during a pre-trip inspection, the driver should:
Drive without making any changes.
If a pre-trip inspection reveals a load to be oversize, the driver must confirm that all required signs, flags, lamps, and reflectors are safely and properly mounted, and that and all required permits are in their possession.
39 . Air tank drains:
Must remain open while driving.
In an air brake system, the air tanks are equipped with drains that allow water and compressor oil to be removed from the system. If allowed to build up, water and compressor oil can damage an air brake system.
40 . A slack adjuster should move no more than ____ from where it is attached to the push rod.
Before a trip, you should check each slack adjuster after parking, setting wheel chocks, and disengaging the parking brake. Pull the slack adjusters to make sure that they do not move more than about one inch from where the push rod is attached. If they move more than one inch, they may be out of adjustment and will need to be fixed.
41 . During a vehicle inspection, ensure that lug nuts are all of the following, except:
Free of rust.
During a vehicle inspection test, you must ensure that all lug nuts are present, free of cracks and distortions, and showing no signs of looseness, such as rust trails or shiny threads. Verify that all bolt holes are free of cracks and distortions.
42 . Once stopped as a part of the stop/start maneuver, you should:
Park in front of a fire hydrant.
Once you have stopped as a part of the stop/start maneuver during the on-road driving skills test, you must activate your four-way flashers and shift into neutral or park. You must not block any driveways, intersections, fire hydrants, or signs.
