It is more like car length than seconds when following another car. You should be at least 2 car lengths from the other car.
Rule of thumb, 1 car length every 10 mph
one car length for each 10mph
The average length of a vehicle is 17feet
Rule of thumb is 1 vehicle length for each 10 mph.
10-15 feet . You need to be 2 full seconds behind. Pick stationary object vehicle in front passes, then count how long until you pass the same object. Not 2 seconds? Increase you following distance! Another rule of thumb is to stay behind one car length for every 10 miles per hour, so at 35 mph you would want to be 3 and 1/2 cars behind the car in front of you.
One car length for every 10 mph.
Answer 1Three seconds. Answer 2 In the United Kingdom and most of Europe, it is advised that you leave at least one whole car length between you and the vehicle in front. If the road is wet or icy, you are advised to leave at least two whole car lengths between you and the vehicle in front. Driving too close to another vehicle could get you pulled over for reckless driving and endangering life on the road.

There is no set number of feet of following distance. Too arbitrary. Even the old "one car length for every 10mph" for cars is inaccurate, that's too close-- and also arbitrary. Follow no closer than you can react in the event of anything unexpected. No closer than you can see the truck cab mirrors, there is a rule --if you can see the drivers mirrors, he/she can see you. If you are too close to see mirrors, back off..way off. Weather plays a role. Speed, condition of road. Two-lane high-speed, or Freeway. Far behind enough you can see what's ahead. I have learned patience, my life is worth more than getting to my destination 5 minutes sooner. OK, this is a long-winded way of saying a long way back.

0. Since the "following" triangle is too small to be seen, its sides must be of length 0.
