Maine Truck Following Distance
150 feet is Maine's truck number, and it only applies behind ANOTHER truck, out past the business or residential district (29-A M.R.S. 2066). It does not stop you from passing. Behind a car or in traffic, the rule that governs is the same statute's reasonable-and-prudent standard, and that's the tailgating ticket — a traffic infraction with 2 points. That 150-foot line is far shorter than the CDL 7-second gap a loaded rig actually needs.
A detail here is flagged medium confidence — confirm with the state statute before you rely on it.
