With stretches of Interstate 90 and other major roads capped at 80 mph, it’s easy to wonder just how strictly speed limits are enforced.

Many drivers assume there’s wiggle room—like going 10 mph over the limit without repercussions—but is that really the case?

Montana’s Speeding History: From "Reasonable and Prudent" to Strict Enforcement

Montana has a unique history when it comes to speed limits. For decades, the state didn’t have a formal speed limit on its highways during daylight hours. Instead, drivers were required to maintain a “reasonable and prudent” speed based on road conditions. Violations were minimal, and fines were often as low as $5, earning Montana a reputation as a driver’s paradise.

Consequences of Speeding in Montana

Montana employs a points system to track traffic violations.

Accumulating too many points within a set timeframe can lead to severe consequences, including the suspension or revocation of your driver’s license. Here’s how common infractions stack up in the point system:

• Speeding: 3 points
• Driving without insurance: 4 points
• Racing: 5 points
• Reckless driving: 5 points
• DUI: 10 points
• Other moving violations: 2 points

If you accumulate 30 points or more within a three-year period, your license will be revoked for three years.

Can You Legally Drive 10 MPH Over the Speed Limit in Montana?

Under Montana law, there’s only one specific situation where exceeding the speed limit by up to 10 mph is allowed: passing another vehicle on a two-lane road. If you’re in a designated passing zone, you may temporarily increase your speed to safely overtake slower traffic. Outside of this exception, driving even slightly over the posted speed limit is illegal and subject to penalties.

For reference, this exception is outlined in Montana Code 61-8-303, which governs speed restrictions and provides guidelines for passing safely.

The Bottom Line: Drive Smart, Stay Safe

While Montana’s highways may feel like the perfect place to stretch your vehicle’s capabilities, the law is clear: speed limits exist for a reason. Outside of specific passing scenarios, going even a few miles over the limit can result in fines, points on your record, and increased insurance premiums.

If you’re planning a road trip or daily commute, remember that it’s not just about avoiding tickets—it’s about keeping yourself and others safe. So, enjoy the scenic drives Montana offers, but keep an eye on that speedometer.

Summary:

Montana’s speed limits are some of the highest in the U.S., but exceeding them is generally illegal, with one exception: you can go up to 10 mph over the limit when passing another vehicle on a two-lane road in a designated passing zone. Beyond this, speeding can result in fines, points on your driving record, and even license revocation under Montana’s strict enforcement and point system. While Montana’s highways are known for their open roads, staying within the limit ensures safety and avoids penalties.
