Pennsylvania Truck Following Distance
No fixed feet in Pennsylvania. Out on the open road, outside an urban district, following another truck or a rig towing another vehicle, leave a hole big enough for a passing car to pull in (75 Pa.C.S. 3310(b)). That convoy rule sets no number and never blocks passing. The tailgating ticket comes off the general reasonable-and-prudent rule (3310(a)): $25 fine plus court costs, 3 PennDOT points, and a serious offense on a CDL.
