Oversize Restrictions on Roads and Bridges in Connecticut
Connecticut complies with the Federal Bridge Formula for calculating safe load limits on bridges. Additional roadway restrictions for oversize vehicles include, but are not limited to:
Avoiding active construction zones
Obeying all posted warnings within work areas
Giving priority to emergency vehicles and law enforcement when encountered on the road.
Connecticut Amber Light Permit Guidelines
Use of Amber Lights for Escort Vehicles: In Connecticut, any vehicle escorting an oversize or overweight load must be equipped with an amber warning light mounted on the roof. These lights serve as a safety measure to alert nearby motorists of potentially hazardous or slow-moving vehicles. The required fee (typically $20)
- Purpose of the Amber Light Permit: The Connecticut Department of Motor Vehicles (DMV) requires a special permit for vehicles that need to operate with yellow or amber lights including flashing variants. These are commonly used on escort vehicles, highway maintenance trucks, and others as outlined in state law. The permit legalizes the use of such warning lights and ensures compliance with public safety regulations.
- Who Needs a Permit?: Most vehicles must have an amber light permit unless specifically exempted by law. Exemptions include:
Authorized wreckers (tow trucks)
Rural mail delivery vehicles
Vehicles owned, leased, or registered to federal, state, or local government agencies (when legally authorized to display amber lights) - Permit Issuance and Compliance: Once approved, the permit allows legal operation of amber lights as specified. Operating such lights without a permit, when one is required, may result in fines or other enforcement actions.

Length-Based Requirements:
- Divided Highways:
Loads exceeding 100 feet require one escort.
Loads exceeding 120 feet require two escorts - Undivided Highways:
Loads longer than 80 feet must have one escort.

- Loads over 12 feet wide require one escort on divided highways and two on undivided highways.
- If the load is over 13 feet 6 inches wide, two escorts are needed regardless of the roadway.
- Loads exceeding 14 feet 11 inches (effectively 15 feet or more) may require three escorts.
Height-Based Requirements:
- For heights over 14 feet, a lead escort with a height pole is required, and a route survey must be completed prior to permit issuance.

Connecticut Banners, Lighting & Flage Requirement

Any overhang greater than 4 feet must be flagged during daylight and equipped with lights after dark.
Bright safety flags (commonly red or orange) must be attached to each corner of the vehicle and placed at the widest points of the load to enhance visibility.
Additional Information

If a load is overweight and the weight can be reduced by detaching the blade, then it must be transported separately.
