Rules of the Road
In heavy rain or on slippery roads, the recommended minimum following distance behind the vehicle ahead should increase to at least:
Show Answer & Explanation
Correct Answer: B. Three to six seconds depending on conditions
Slippery roads double or triple stopping distance. Increase your following distance to 3–6 seconds to give yourself room to brake safely. This single habit prevents many of the rear-end collisions that occur in snow, rain, and ice.
Why the other answers are wrong
- A.Stay at two seconds — conditions don't change the ruleThe rule adjusts with conditions; two seconds is only for dry, clear roads.
- C.One second — to reduce exposure to the stormReducing distance in bad weather is the opposite of safe practice — stopping distance is longer, not shorter.
- D.Keep any distance as long as you can see the vehicle aheadAny distance is too vague; the handbook specifies at least 3 seconds for adverse conditions.
