15 . When approaching a downgrade, how can you reduce the amount of braking that will be needed?
Turn off the engine.
Always shift to a lower gear before starting down a hill. Doing this will help your vehicle maintain a safe speed without you needing to use the brakes too much.
16 . Black ice is usually very thick.
Black ice is a layer of ice that is thin and clear enough for the road to be visible through it. This makes the road look as if it is merely wet.
17 . When trying to put out an electrical fire:
Use a Q extinguisher.
B and C type fire extinguishers are designed to work on electrical fires. Water should never be used to extinguish an electrical fire because doing so could result in an electrical shock.
18 . What is a way to warn drivers behind you that you will be slowing down?
Turn all lights on and off several times.
To alert drivers behind you that you plan to slow down, tap your brake pedal lightly a few times to make the brake lights flash.
19 . Distracted driving:
Distractions while driving can be physical (such as reaching for an object), mental (such as making conversation with a passenger), or both (such as holding a phone to send texts). Strategies to help you avoid distracted driving include pre-programming radio stations; planning out your route in advance; avoiding complex or emotionally taxing conversation while driving; adjusting your mirrors before setting out; and not eating, drinking, or smoking while behind the wheel.
20 . Brakes may get out of adjustment:
If they get wet.
