About 7 to 10 seconds

This is my guess...from what I could figure out in a hurry...

Anybody else got a guess?

Let me guess, and I am trying to quote the police now.

"The answer, boy is about twice as far as you were following that truck in front of you. Don't you know tailgating is frowned upon around here?"

That sounds like a cop answer to me! I once knew a cop that would spend his entire shift sitting on the same route every at regular intervals and always ticketed at least four trucks every single time. I could never understand why the drivers wouldn't remember that he is there.

I try to leave 3-4 truck lengths. Sometimes someone will cut in the safety zone and you have to stop fast. The room doesn't seem like enough.

If a cop is asking you, chances are that there is no right answer! But if its not a cop I would say at least a couple hundred feet.

Going 55 MPH in dry weather is length of football field, so here is less than 1/2 football field.

It doesn't matter if you leave the right amount of room in front of you are not. Someone will swerve into the space and cut you off and then you are tailgating. If you close up to stop people from trying to cut in front of you, you are too close also.
