Minnesota's left-lane and keep-right rules are found in Minnesota Statutes §169.18.
On roadways with more than one lane traveling in the same direction, a driver must move out of the leftmost lane to allow another vehicle to pass when practicable under the existing conditions.
The rule does not apply when the driver is overtaking and passing another vehicle, preparing for a left turn, preparing to exit a controlled-access highway on the left side, using a lane designated for a specific type of traffic, or operating an authorized emergency vehicle.
On roadways with only one lane traveling in the same direction, a vehicle moving slowly enough to create a traffic hazard must stay as close as practicable to the right-hand curb or edge of the roadway.
Minnesota also allows officials to designate lanes specifically for slow-moving traffic, and drivers must obey those lane-use signs.
This makes Minnesota one of the states with a direct requirement to leave the leftmost lane for faster traffic when doing so is practicable, rather than relying only on a general slower-traffic keep-right rule.
Exceptions
- Overtaking and passing another vehicle traveling in the same direction.
- Preparing for a lawful left turn.
- Preparing to exit a controlled-access highway from the left side.
- Using a lane designated and posted for a specific type of traffic.
- Operating an authorized emergency vehicle.
- Conditions where moving right is not practicable or safe.
Penalties
A violation of Minnesota's traffic-lane rules may result in a traffic citation. The exact fine and total amount due can depend on the specific violation, court costs and other assessments.
Drivers should verify the current amount shown on the citation or with the court handling the case.
