Under poor driving conditions, how should you apply the two-second rule?

• A. Shorten the following distance
• B. Maintain the same distance
• C. Increase the following distance
• D. Ignore the rule

Answer: (C)

Under poor driving conditions, you need more stopping distance than the two-second rule provides. The two-second guideline helps in normal, dry conditions, but rain, snow, ice, or reduced visibility increase stopping distances and can slow your reaction time. So you should extend the following distance beyond two seconds—typically to three or four seconds depending on how bad the conditions are. A practical way to gauge this is to pick a fixed object ahead and ensure you don't pass it for at least three seconds after the vehicle in front passes it. In adverse conditions, slow down and avoid abrupt moves to maintain a safe buffer behind the vehicle ahead.
