Which rule is used for determining safe following distance in good driving conditions?

• A. The One-Second Rule
• B. The Two-Second Rule
• C. The Three to Four Second Rule
• D. The Five-Second Rule

Answer: (C)

The Three to Four Second Rule is the standard guideline for determining a safe following distance under good driving conditions. This rule suggests that drivers should maintain a space of three to four seconds between their vehicle and the one in front, allowing ample time to react to sudden stops or emergencies. This interval helps ensure that drivers have enough distance to safely stop without risking a collision if the vehicle ahead decelerates unexpectedly. By measuring the time it takes for your vehicle to reach a stationary object once the vehicle in front passes it, you can effectively gauge a safe following distance. In varying conditions, such as inclement weather or poor visibility, extending this distance is advisable to accommodate the increased stopping distance needed.
