AK DMV Vehicle Operation and Maintenance 5

Question 1

How does an anti-lock braking system (ABS) change how you should brake in an emergency?

Accepted Answer

Press and hold the brake pedal firmly; do not pump the brakes

Answer

ABS automatically pulses the brakes to prevent wheel lockup, so the driver should apply steady, firm pressure.

Question 2

What routine maintenance most directly extends the life of your engine?

Accepted Answer

Changing the oil and oil filter at recommended intervals

Answer

Clean oil lubricates and protects internal engine parts, making regular oil changes the most important engine maintenance.

Question 3

Why do batteries fail more often during Alaska winters?

Accepted Answer

Cold temperatures reduce battery cranking power while the engine needs more power to start

Answer

A battery can lose a large share of its cranking capacity in subzero cold just when thickened oil makes the engine harder to turn over.

Question 4

If your headlight fails while driving at night, you should:

Accepted Answer

Slow down, use your remaining lights, and get the headlight repaired as soon as possible

Answer

Driving with one headlight reduces visibility and is illegal, so slow down and repair it promptly.

Question 5

What does the temperature warning light or gauge in the red zone indicate?

Accepted Answer

The engine is overheating and you should stop driving as soon as safely possible

Answer

A red-zone temperature reading means the engine is overheating and continuing to drive can cause severe engine damage.
