Difficulty: EasySpeed Control and Following Distance

When driving on a slippery road covered in rain, how should a driver adjust their following distance behind the vehicle ahead?

  1. Increase the following distance to allow more space and time to stop safelyAnswer
  2. B
    Maintain the standard 3-second distance because posted speed limits guarantee safe stopping on wet roads
  3. C
    Reduce the following distance to 1 second to prevent other vehicles from cutting in front
  4. D
    Keep the exact same following distance unless driving through an active school zone

Answer

Increase the following distance to allow more space and time to stop safely
Increasing the following distance on wet roads is necessary because slippery pavement reduces tire traction, requiring significantly more time and distance to stop safely.

Step-by-Step Solution

1
Identify the environmental driving hazard
Recognize that wet and slippery road surfaces reduce tire traction.
Lower traction increases the physical distance required for a vehicle to come to a complete stop.
2
Determine the appropriate safety adjustment
Increase the following distance beyond the normal 3-to-4 second rule.
Creating a larger safety buffer provides adequate reaction time and stopping space to avoid rear-end collisions.
