## Frequently Asked Questions
### Can oversize trucks travel on the Merritt Parkway (Route 15) in Connecticut?
No. All commercial vehicles, trailers, and oversize loads are strictly prohibited on Route 15 (Merritt Parkway and Wilbur Cross Parkway) due to historic low clearance bridges.

CTDOT mandates pilot cars for loads over 12' wide on 2-lane roads and over 13'6" on multi-lane highways. Loads exceeding 15' wide, 14'6" high, or 130,000 lbs require Connecticut State Police escorts.

### What are the travel restrictions on weekends in Connecticut?
Movement is allowed on Saturdays until 12:00 noon for loads not exceeding 12' wide and legal height. No travel is permitted on Sundays or major holidays.
