You may NOT pass a vehicle on the right
- when the vehicle is in a left-turn lane.
- on highways that have at least two lanes traveling in the vehicle's direction.
- when you're in a left-turn lane.
In Montana, there are only a few situations in which you may legally pass a vehicle on the right. You may pass a vehicle on the right when it is making or about to make a left turn. You may also pass a vehicle on the right when there are two or more lanes going in the same direction as the vehicle is. A left-turn lane is only used for making left turns (and U-turns where permitted).
