Per-trip oversize load permits
Any dimension exceeding 8'6" wide, 13'6" tall, 53' long, or 80,000 lbs gross requires a per-trip oversize permit in every state of travel under 23 CFR §658. We file same-day from $85 per state per trip plus state DOT fees, with engineering review for superloads.
Standard vs superload permits
Standard oversize permits cover loads modestly above the federal default — say 10 feet wide, 14 feet tall, 60 feet long, or 90,000 lbs GVW. These permits typically issue within 1-3 business hours during state DOT business hours and cost $50-$200 per state per trip in DOT fees. Superloads (typically 16+ feet wide, 17+ feet tall, 200+ feet long, or 200,000+ lbs) trigger additional engineering review and permit fees.

Oversize load permit questions
What dimensions trigger an oversize permit?
The federal default per 23 CFR §658 is 8'6" wide, 13'6" tall, and 53' length on a single trailer (or 28' on each trailer of a double-trailer combination). State limits vary slightly — most match the federal defaults, some allow taller loads on specific routes. Any dimension above the limit requires a per-trip oversize permit in each state of travel. GVW above 80,000 lbs separately triggers an overweight permit.
What is a superload and when do I need one?
A superload is an oversize load exceeding state-specific superload thresholds — typically anything over 16 feet wide, 17 feet tall, 200 feet long, or 200,000 lbs. Superloads need a separate engineering review before the permit issues; the state DOT runs a route study, may require police escort, may impose time-of-day or seasonal restrictions, and the permit fee is substantially higher than a standard oversize permit. Lead time for a superload permit is typically 5-15 business days.
Can I haul oversize at night?
Most states prohibit oversize movement during night hours and on weekends/holidays unless the permit specifically authorizes it. Daytime restrictions also apply on certain routes (urban areas during commute hours, narrow bridges with traffic-control requirements). Each permit specifies the authorized travel windows; violating them voids the permit and exposes the carrier to citations.
