What following distance should you maintain behind the vehicle in front under normal conditions?

• A. A four-second gap behind the vehicle in front
• B. A two-second gap behind the vehicle in front
• C. A one-car-length gap behind the vehicle in front
• D. Six seconds behind the vehicle in front

Answer: (B)

Maintaining a safe following distance means leaving enough space to notice and react if the car in front brakes suddenly. Under normal driving, the recommended distance is a two-second gap behind the vehicle ahead. This rule gives you time to perceive the brake lights, react, and brake to a stop without colliding. It ties the distance to your speed and isn’t tied to a fixed car length, which can be unreliable because vehicles vary in size and braking performance. A four-second gap would be extra safe but isn’t the standard for normal conditions, and a six-second gap is more spacing than typically needed and can disrupt traffic flow.
