Regulations change. This page summarises published Louisiana rules as reviewed October 2026 and is not legal advice; the conditions printed on your permit control. Note: Legal height is 14 ft on interstates and 13.5 ft on non-interstate highways (13.5 used here). The manual does not state the number of private escorts per width tier, so escortTwoWidthFt is null (state police front and rear escorts needed over 18 ft wide; state police over 16 ft). Multilane note: the escort travels behind the load and a pole truck is also needed in front. Holiday list not given in the manual. Superloads and route approvals have extended processing times.
