Which statement about the following distance in poor conditions is true?

• A. The two-second rule applies the same in all conditions.
• B. Drivers should never use two-second rule.
• C. The two-second rule helps you maintain a safe following distance in good conditions and should be increased in poor conditions.
• D. The two-second rule is a guideline for signaling.

Answer: (C)

The main idea is that following distance must adapt to conditions because stopping distance grows when roads are slick or visibility is reduced. The two-second rule is a practical baseline for maintaining a safe gap in normal, good conditions. In poor conditions—rain, snow, ice, fog, or glare—you should increase that distance to give yourself more time to react and brake. That extra cushion accounts for slower traction and longer stopping distances, and you should adjust your speed accordingly. To apply it, pick a fixed object on the road and watch when the lead vehicle passes it, then start counting seconds; if you reach the object before you finish counting to two, you’re following too closely. This rule isn’t about signaling; it’s about keeping an appropriate following distance, which you adjust upward as conditions worsen.
