Safeway Driving Reality Check Adult Class Practice Exam

A safe following distance is the cushion you need to react and stop if the vehicle ahead slows or stops suddenly. On normal roads, you should keep enough space to comfortably brake without hitting the car in front, which gives you time to perceive a hazard, decide, and act. That’s why this option is best: it focuses on leaving room to react rather than chasing the car ahead or crowding them. Tailgating leaves you with zero margin if that car brakes hard, following at the same distance doesn’t create any safety buffer, and staying inches behind is an unsafe habit that can’t cover you if conditions change. A practical guideline is the three-second rule (or more in poor weather or low visibility): pick a fixed point ahead, and ensure you pass it three seconds after the vehicle in front does. Increase that time in rain, snow, or icy conditions, or when following trucks or in heavy traffic.
