What is the customary following distance for most drivers?

Answer: B — 20 feet

The customary following distance for most drivers is 20 feet. It is important for drivers to maintain a safe following distance in order to have enough time to react and stop in case of an emergency. Option A of 30 feet is too much distance and could increase the likelihood of another driver cutting in front, causing the driver to suddenly brake or swerve. Option C of 10 feet is also too close, not allowing enough time to stop in case the front driver brakes suddenly. Option D of 5 feet is extremely dangerous and considered tailgating, which can result in accidents and put both drivers at risk. The safest and most commonly recommended following distance is 20 feet.
