Maryland Truck Following Distance
No fixed feet. Maryland's truck rule is a convoy gap: outside a business or residential district, behind another truck or a vehicle towing another, leave room for a passing car to merge (Md. Transp. 21-310(b)). No number, and it never stops you passing. Tailgating tickets ride on the general reasonable-and-prudent rule (21-310(a)): a payable citation with a modest preset fine, 2 points - 3 if it causes a crash - up to $500 in court.
