New Mexico Truck Following Distance

300 feet, the one hard number in this batch. Behind another truck, or a rig towing, outside a business or residence district, stay back at least 300 feet (NMSA 66-7-318(B)); you may still close up to pass. It does not apply in town or behind a car. The caravan rule (66-7-318(C)) carries its own 300 feet and is what exempts funeral processions, escort vehicles and non-lead platoon vehicles. Behind a car the rule is reasonable and prudent (66-7-318(A)). Following too closely is a $25 penalty assessment (66-8-116), and a work zone does not double it; only speeding doubles in a posted double fine zone.
