Thresholds, escorts, and curfews
- Legal max before a permit: Permit needed over 8'6" wide, 13'6" high, 80,000 lb gross, or over legal length (53 ft semitrailer), per Chapter 45 of Title 21. DelDOT issues online, and the permit is valid 5 days.
- Escort / pilot car: Width over 13' takes one escort (rear on a multi-lane highway, front on a two-lane); over 14' one front and one rear; over 15' front, rear, and Delaware State Police. Length over 90' takes one rear escort; 100 to 120' one front and one rear; over 120' front, rear, and State Police.
- Superload: Superload at 120 ft or longer, 15 ft wide, 15 ft high, or 120,000 lb gross or more. Delaware State Police escort comes in at that length or width, and DelDOT reviews the route and structures before issuing.
