Car speed limits in Connecticut (2026)
Last reviewed: 9 October 2026
In short: Connecticut has no fixed statutory limit for built-up areas: limits are set by the State Traffic Administration or the town. It is an offence to drive faster than 55 mph on highways, and limited access highways may have limits up to 65 mph. Speeding fines are doubled in signed school zones and in construction zones while work is ongoing.
