A driver is following a large commercial truck on a dry highway. To maintain a safe following distance, what is generally recommended for passenger vehicles in ideal conditions?
- AMaintain a 4-second following distance.
- BMaintain a 3-second following distance.
- CMaintain a 1-second following distance.
- DMaintain a 2-second following distance.
Show answer & explanationAnswer & explanation
Correct answer: A. Maintain a 4-second following distance.
While a 2-second rule is a minimum for passenger vehicles, large commercial trucks require more space due to their size, weight, and longer stopping distances. A 4-second following distance provides a safer buffer.
Why the other options are wrong
- B. A 3-second distance is better, but 4 seconds is generally recommended for large trucks.
- C. A 1-second distance is dangerously close, providing insufficient reaction time.
- D. A 2-second distance is a minimum for passenger cars, but insufficient for following large trucks.
Following Distance (Trucks)
The safe amount of time or space a driver should maintain behind a large commercial truck to allow for adequate reaction and stopping time, typically greater than for passenger vehicles.
- Large trucks have longer stopping distances due to weight.
- Reduced visibility for the driver behind a truck.
- Increased following distance provides crucial reaction time.
Memory trick: Seconds count, don't be a dunce, leave space for a safe response!
