What is the speed limit on unmarked roads in Oklahoma?

Oklahoma follows the basic speed rule. This means that you cannot go faster than the conditions would dictate, regardless of the speed limit marked. Failure to do so can result in a fine up to $384.90 and 30 days in jail. With that said, the following are the maximum speeds allowed:
• Four-lane divided and super two-lane highways – 70 mph
• Turnpikes – 75 mph
• Two-lane highways – 65 mph
• County roads – 55 mph
• Highways within state parks or wildlife refuges – 45 mph
• Other roads in state parks or wildlife refuges – 35 mph
• School zones outside of a municipality – 25 mph
