In Vermont the rural freeways are posted at the maximum speed limit of 65 mph (105 km/h). On urban freeways and rural two-lane limited access roads, the speed limit is 55 mph (89 km/h), such as on I-189 and Interstate 89 in Burlington, and US Route 7 and Vermont State Route 279 outside of Bennington. The standard speed limit is 50 mph (80 km/h) and this is applied to rural two-lane roads.
The speed limit drops from 65 mph (105 km/h) on rural highways to 40 mph (64 km/h) at the approach to the Canada–US border on Interstates 89 and 91, at Highgate and Derby Line, respectively.
In school zones, the speed limit can range from 15 mph (24 km/h) to 25 mph (40 km/h), depending on local authority. The minimum speed is defined at 40 mph (64 km/h) only on Interstate highways. That includes where the limit is posted at 55 mph (89 km/h) and 65 mph (105 km/h). However, as old signs are being replaced, the “40 MINIMUM” (64 km/h) is being phased out, keeping only “SPEED LIMIT 65” (105 km/h).
