A 75 mph speed limit is observed on certain interstates in states such as Kansas, Louisiana, and Maine. These maximum posted speeds are typically found on specific segments of rural or urban interstate highways, reflecting varied state regulations and road conditions.
States Permitting 75 mph Speed Limits
Speed limits on interstates can differ significantly between states and even between rural and urban sections within the same state. A 75 mph speed limit signifies a higher maximum speed permitted on these roadways.
The following states currently have sections of their interstates where the maximum posted speed limit is 75 mph:
| State | Road Type | Speed Limit (mph) |
|---|---|---|
| Kansas | Rural Interstates | 75 |
| Kansas | Urban Interstates | 75 |
| Louisiana | Rural Interstates | 75 |
| Maine | Rural Interstates | 75 |
| Maine | Urban Interstates | 75 |
These limits are established based on engineering studies, traffic volume, and safety considerations. While Kansas and Maine permit 75 mph on both rural and urban interstates, Louisiana's 75 mph limit is specifically for rural interstates, with urban interstates typically capped at 70 mph.
