Drivers should allow how many seconds distance based on speed when following motorists?

Allowing a distance of 2-4 seconds when following other vehicles is important for maintaining a safe following distance. This range helps ensure that drivers have adequate time to react to sudden stops or emergencies. The time interval correlates with the speed at which a vehicle is traveling; as speed increases, the distance needed to stop safely also increases. By keeping a 2-4 second gap, drivers can better assess their surroundings, deal with potential hazards, and provide themselves with sufficient stopping distance in various traffic conditions. This practice not only contributes to driving safety but also helps avoid rear-end collisions.
