Is It Ever Legal to Pass on the Right in Montana?
Most of us are used to the idea that passing another car means using the left lane, but what about when that lane is blocked, or someone’s making a turn? If you’ve ever wondered whether passing on the right is allowed in Montana, you’re not alone. The answer isn’t a simple yes or no - it depends on the situation.
Montana Law Allows It, But Only in Certain Situations
Montana Code Annotated § 61-8-324 outlines when a vehicle can legally pass on the right. It’s allowed only when the vehicle you’re passing is making or about to make a left turn, or if you're on a roadway wide enough for two or more lanes of traffic in the same direction. In other words, if there’s enough space to do it safely, and you’re not driving on the shoulder or cutting corners, you’re probably in the clear.
What You Absolutely Can’t Do
Even if it’s legal, there are big restrictions. You can’t:
• Pass on the right by driving off the paved road or onto the shoulder.
• Weave around traffic dangerously or without enough space.
• Pass on the right where the road narrows or there's no designated lane.
Doing any of the above could get you a ticket for reckless driving or improper lane usage, both of which carry fines and points on your license.
It All Comes Down to Safety
The law says it must be done “under conditions permitting such movement in safety.” So even if passing on the right is technically allowed, if a police officer believes your move was unsafe, maybe due to speed, poor visibility, or traffic flow, you could still be pulled over.

What About Multi-Lane Roads and Highways?
On highways or city roads with multiple lanes going in the same direction, passing on the right is perfectly legal as long as you stay in your lane and don’t cut someone off. This is why you’ll often see faster traffic pass on both sides on interstates, though it’s still good etiquette to use the left lane for passing when possible.
Bottom Line: Know When It's Safe and Legal
So yes, passing on the right can be legal in Montana, but only when conditions are just right. Make sure there’s a dedicated lane, enough space, and no risk to other drivers. When in doubt, wait it out. A few extra seconds are always better than an expensive traffic ticket.
