What is the recommended following distance on wet pavement for emergency vehicles?

• A. One second
• B. Five seconds
• C. At least two seconds
• D. None

Answer: (C)

When roads are wet, stopping distances grow because tires grip less and hydroplaning can occur. That means you need more space to react and brake safely. The recommended rule is to keep at least a two-second gap between your vehicle and the one ahead. A simple way to check is to pick a fixed point on the road and count when the lead vehicle passes it to when your vehicle passes it; if you finish counting before you reach the point, you’re too close and should increase the distance. One second is not enough on wet pavement, and five seconds is more than the basic requirement. There’s no scenario where you should have no minimum following distance. In emergency driving, you can adjust for speed and conditions, but the standard minimum on wet pavement is at least two seconds.
