Arizona Truck Following Distance
No fixed feet. Behind another truck or a rig towing, outside a business or residence district, leave enough room for a passing car to merge back in (ARS 28-730(B)) — a convoy gap, not a set distance, and passing is still allowed. Behind a car, in traffic, or in town the rule is reasonable and prudent (28-730(A)), which is the ticket a trooper writes for tailgating, enforced by the CDL seconds gap. Civil violation, roughly $200 with surcharges.
