The fastest speed limit in Oklahoma is 80 miles per hour (mph). This speed limit is specifically designated for certain segments of turnpike within the state, such as portions of the H.E. Bailey Turnpike (Interstate 44) and the Indian Nation Turnpike.
While 80 mph represents the highest legal speed, Oklahoma implements varying maximum posted speed limits across different types of roadways to ensure safety and efficiency.
Oklahoma Maximum Posted Speed Limits
| Road Type | Maximum Posted Speed Limit (mph) |
|---|---|
| Specified segments of road | 80 |
| Rural Interstates | 75 |
| Other Limited Access Roads | 70 |
These speed limits are determined based on factors like road design, traffic volume, and the surrounding environment. It is crucial for drivers to always observe and adhere to the posted speed limits for their safety and the safety of others on Oklahoma's roads.
