Vehicle Safety and Maintenance Flashcards

How often should you check your tire pressure?

Answer: At least once a month and before long trips

Tire pressure should be checked at least once a month and before long trips because pressure can change with temperature and slow leaks.

What does it mean when the oil pressure warning light comes on while driving?

Answer: Stop safely as soon as possible and turn off the engine

Low oil pressure can cause severe engine damage within seconds, so you must stop safely and shut off the engine immediately.

What is the recommended minimum tread depth for tires before they must be replaced?

Answer: 2/32 of an inch

The legal minimum tire tread depth in the US is 2/32 of an inch; below this level tires lose the ability to channel water and grip the road safely.

When should you replace your windshield wipers?

Answer: When they streak, skip, or leave areas uncleared

Wipers that streak or miss areas reduce visibility in rain and should be replaced immediately regardless of age.

Which fluid should you check to ensure your brakes function properly?

Answer: Brake fluid

Brake fluid transfers hydraulic pressure to the brake calipers; low or contaminated brake fluid can cause brake failure.

What should you do if your 'Check Engine' light turns on and stays on steadily?

Answer: Have the vehicle inspected by a mechanic soon

A steady Check Engine light indicates the vehicle's computer has detected a fault; the car is usually safe to drive short-term but should be diagnosed promptly.

How can you tell if your vehicle's headlights need to be replaced or realigned?

Answer: Other drivers flash their lights at you or your illumination seems dim and uneven

Oncoming drivers flashing at you suggests misaligned headlights, while dimness or uneven beams indicates a bulb is failing.
