Another commonly used following distance rule is to leave about one second of space per 10mph of following distance. This would mean three seconds of following distance at 30mph, six seconds at 60mph, and so on. Faster speeds mean drivers should leave greater following distances.

How do you calculate safe 2 second following distance?

How many feet do you follow behind a car?

Car: 243 feet (about 16 car lengths) – This gives you the necessary space to stop safely. Semi-Truck: 300 feet (about 20 car lengths) – Semis carry heavy loads, so more than slamming on the brakes, something can fall off or out of the truck, and you need time to react and avoid the debris.
