Question: In heavy rain, double your following distance to at least:

Answer options:

• 1 second
• 2 seconds ✅ 4 seconds
• 6 seconds

Correct answer: 4 seconds

Explanation: Under Ontario rules, the standard safe following distance on dry roads is at least two seconds. In heavy rain, drivers must double this distance to at least four seconds to compensate for reduced visibility and increased braking distances on wet pavement. One second is dangerously insufficient under any condition, while two seconds is only appropriate for ideal dry roads. Six seconds is typically reserved for ice or snow, making four seconds the precise requirement for rain. Memorizing space-chasing rules for different weather conditions is essential for passing the G1 knowledge test, as road safety questions frequently test these specific time intervals.
