## Frequently Asked Questions
### How long does ODOT take to process an Ohio oversize permit?
Routine single-trip permits are typically processed by ODOT within 2–4 business hours. Superloads requiring bridge structural reviews take 3–5 business days.

### What are Ohio pilot car rules for oversize loads?
Ohio requires 1 escort for loads over 13' wide or over 90' long. Loads over 14'6" wide or over 14'10" high require 2 escorts. Loads over 16' wide or exceeding 13' wide with 120,000+ lbs require Ohio State Highway Patrol escorts.

Yes. Permits are issued at entering toll plazas. Vehicles over 11' wide or 112' long require advance authorization and pilot cars.

### Can oversize trucks stop for fuel or food off the permitted route in Ohio?
No. Ohio regulations strictly forbid deviating from the permitted route for food or fuel. All planned truck stops must be specifically designated on the permit.
