Question 1

What does ABS stand for in automotive safety?

Accepted Answer

Anti-lock Braking System

Answer

Anti-lock Braking System prevents wheel lockup during hard braking, allowing the driver to maintain steering control while stopping.

Question 2

How do airbags protect vehicle occupants?

Accepted Answer

By inflating rapidly to cushion the impact and spread crash forces over a larger body area

Answer

Airbags deploy in milliseconds during a collision, inflating to create a cushion that spreads impact forces across a larger body area, reducing injury severity.

Question 3

What is the primary purpose of Electronic Stability Control (ESC)?

Accepted Answer

To prevent loss of control by automatically applying brakes to individual wheels

Answer

ESC detects when a vehicle begins to skid and automatically applies brakes to individual wheels to help the driver maintain control and directional stability.

Question 4

When should you replace your vehicle's tires?

Accepted Answer

When tread depth reaches 2/32 of an inch or the wear indicators are visible

Answer

Tires should be replaced when tread depth reaches 2/32 of an inch. Most tires have built-in wear indicators (bars) that become flush with the tread at this depth.

Question 5

What is the correct seatbelt wearing position?

Accepted Answer

Lap belt across the hips and shoulder belt across the chest and shoulder

Answer

The lap belt should sit snugly across the hips (not the stomach) and the shoulder belt should cross the chest and collarbone (not the neck), ensuring proper restraint during a crash.
