Difficulty: EasySpeed Control and Following Distance

You are driving on a highway during a rainstorm when the road surface becomes wet and slippery. How should you adjust your following distance behind the vehicle in front of you?

  1. Increase your following distance to 4 seconds or more to allow additional stopping space.Answer
  2. B
    Maintain the standard 3-second following distance regardless of weather conditions.
  3. C
    Maintain the maximum posted speed limit and reduce following distance to follow the lead vehicle's tracks.
  4. D
    Reduce your following distance to one car length per 10 mph under all weather conditions.

Answer

Increase your following distance to 4 seconds or more to allow additional stopping space.
When driving on wet or slippery roads, tire traction is reduced, which increases the distance needed to stop safely. Increasing the following distance to 4 seconds or more creates an adequate safety cushion to react and brake smoothly without colliding with the vehicle ahead.

Step-by-Step Solution

1
Identify the environmental hazard and its impact on vehicle control.
Rain and wet roads reduce tire traction and significantly increase total stopping distance.
Slippery road surfaces lower friction, requiring more time and distance to bring the vehicle to a safe stop.
2
Apply safe driving practices for adverse weather following distance.
Increase the standard 3-second buffer to 4 seconds or more.
Expanding the cushion space compensates for longer braking distances and prevents rear-end collisions.
