Car speed limits in Oklahoma (2026)

Last reviewed: 9 October 2026

In short: Oklahoma sets no fixed statutory figure for most roads: the limit is the speed the Department of Transportation establishes after an engineering and traffic study. Up to 75 mph may be set on rural interstate segments and up to 80 mph on the turnpike system. Marked school zones outside towns have a 25 mph limit at the posted times, and fines are doubled in school zones and in construction zones with workers present.

Notes

  • The limits may be altered as authorized in sections 11-802 and 11-803 of title 47. The statute names fixed figures only for school zones (25 mph outside municipalities), state parks and wildlife refuges (35 mph) and some vehicle classes.
