Oklahoma Truck Lane Restrictions
Oklahoma does not single out trucks. The left-lane rule covers everybody (47 O.S. 11-309). On any road with two or more marked lanes, stay out of the left lane unless you are overtaking and passing. Running the posted speed is no defense, because the law never asks whether you were holding anyone up. You can stay left when merging traffic or road configuration makes the left lane necessary for safety, and the rule lifts on city streets and county roads unless they are an Interstate or a turnpike. A ticket usually runs around $235 to $255 with court costs and can add 2 points.
Some figures on this page are flagged medium confidence. The general rule is solid, but a specific corridor or fine should be confirmed with the state DOT before you rely on it.

Roads, exceptions, and signs
- Where it applies: Any roadway divided into two or more clearly marked lanes. Statewide. The rule lifts inside a municipality's city limits and on county roads, unless that roadway is an Interstate or a turnpike, so it bites hardest on the interstates and turnpikes.
- Statutory. Some corridors post keep-right-except-to-pass signs.
- General rule: 47 O.S. 11-309(4). On any road with two or more marked lanes the left lane is for overtaking and passing only, whether or not you are holding anyone up. The rule lifts inside city limits and on county roads, but not on an Interstate or a turnpike.
What a lane violation costs
The base statutory range is small, but real-world tickets run about $235 to $255 with court costs, and DPS may add 2 points to your license.
