NJMVC Vehicle Safety Systems 1 — Questions and Answers
Question 1: What does ABS stand for in automotive safety?
- Anti-lock Braking System (Correct answer)
- Automatic Brake Support
- Advanced Braking Sensors
- Axle Balance System
Correct answer: Anti-lock Braking System
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?
- By inflating rapidly to cushion the impact and spread crash forces over a larger body area (Correct answer)
- By preventing the vehicle from moving
- By locking the doors
- By absorbing all crash energy
Correct answer: By inflating rapidly to cushion the impact and spread crash forces over a larger body area
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)?
- To prevent loss of control by automatically applying brakes to individual wheels (Correct answer)
- To improve fuel efficiency
- To enhance audio system performance
- To control headlight brightness
Correct answer: To prevent loss of control by automatically applying brakes to individual wheels
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?
- When tread depth reaches 2/32 of an inch or the wear indicators are visible (Correct answer)
- Only when they go flat
- Every year regardless of wear
- When the vehicle fails inspection only
Correct answer: When tread depth reaches 2/32 of an inch or the wear indicators are visible
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?
- Lap belt across the hips and shoulder belt across the chest and shoulder (Correct answer)
- Lap belt only is sufficient
- Shoulder belt under the arm for comfort
- Both belts as loose as possible
Correct answer: Lap belt across the hips and shoulder belt across the chest and shoulder
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.
Question 6: What should you check during a basic pre-trip vehicle inspection?
- Tires, lights, mirrors, fluid levels, and brakes (Correct answer)
- Only the fuel level
- Just the windshield wipers
- Only the engine oil
Correct answer: Tires, lights, mirrors, fluid levels, and brakes
A basic pre-trip inspection should cover tires (pressure and condition), all lights, mirrors, fluid levels (oil, coolant, washer), brakes, and any warning lights.
