Operating Hours, Restricted Travel, and Holiday Restrictions

Truck travel is permitted one-half hours before sunrise and after sunset. This includes weekend travel. Loads that are over 14 feet in width will be prohibited from traveling on the weekend. In densely populated areas where tourists are abundant, travel times may be more limited. In addition, 24-hour travel is limited to overweight loads up to 112,000 pounds.

Signs, Flags, and Lights Requirements

Signs, flags, and lights may be required when moving oversize loads or superloads for the safety of others on the road.

Signs

When width exceeds 10 feet 6 inches, you will require an “Oversize Load” sign on both the front and rear ends of the vehicle.

Flags

Projections and ends of overlength and width loads will require a flag at either end.
