What should a driver do to ensure they maintain an adequate following distance?

To maintain an adequate following distance, it is essential for drivers to gauge how much space they have between their vehicle and the one in front of them. The method of counting seconds after the vehicle in front passes a landmark is effective because it provides a consistent and measurable way to assess the gap. By counting this way—typically three seconds is a recommended distance at regular speeds—drivers can adjust their speed accordingly to ensure they have enough time to react if the vehicle ahead suddenly stops or slows down. This practice is particularly important in preventing rear-end collisions and enhancing overall road safety.

Other actions like speeding up to avoid merging traffic can actually increase risk by reducing reaction time. Driving in the center lane continually does not guarantee an appropriate distance and may not be the best lane for traffic conditions. Using headlights is meant for visibility and lighting up the surroundings, not for measuring distance.
