Minnesota Driving Laws 2026: Speed Limits, DWI BAC and Minnesota DVS Road Rules for the Permit Test

What are the default speed limits in Minnesota when no sign is posted? Minnesota sets 30 mph in urban districts, 55 mph on most highways, and 70 mph on rural interstates. Minnesota DWI: 0.08% for adults, 0.00% for under-21. Minnesota has an Aggravated DWI category for BAC of 0.16% or higher with enhanced penalties. Headlights required from sunset to sunrise and when visibility is less than 500 feet. Texting while driving is banned for all drivers.

1. Speed Limits: 10 MPH Passing Exception

Minnesota has just two default speed tiers, plus a unique provision that allows exceeding the posted limit by 10 mph when lawfully passing on a two-lane highway with a 55+ mph limit. And if you are caught driving over 100 mph anywhere in Minnesota, your license is revoked for a minimum of six months:

Key test point: Minnesotas 10-mph passing exception is unique and tested on the DVS exam, you may exceed the posted limit by 10 mph while lawfully passing on a 55+ mph two-lane highway, but NOT in work zones. Also tested: exceeding 100 mph anywhere in Minnesota triggers an automatic 6-month minimum license revocation. Additional fines apply when passing stopped emergency vehicles.

2. Right-of-Way: Speeding Loses Priority

Minnesota has a specific right-of-way rule tested on the DVS exam: if you approach an intersection at an unlawful speed, you lose the right-of-way privilege associated with driving at a lawful speed. Speed and right-of-way are directly connected in Minnesota law.

4-way stop (all arrive at once)

Driver to the right

4-way stop (one arrives first)

Driver who arrived first

Roundabout / traffic circle

Vehicles already inside the circle

Emergency vehicles (lights/siren)

Emergency vehicle, pull to the right and stop

Pedestrians in crosswalk

Pedestrians always

T-intersection (no signs)

Through road traffic; drivers on the dead-end must yield

Yield sign

Cross traffic and pedestrians always

Merging onto a highway

Traffic already on the highway

3. Turns & Signal Laws

Minnesota requires signals at least 100 feet before any turn or lane change, and continues until the maneuver is complete. Minnesota also requires signaling before passing, use the left signal before moving into the passing lane, and the right signal before returning. Right turns on red are permitted after a full stop:

Right turn on red

Permitted after a full stop unless a sign prohibits it. Yield to pedestrians and cross traffic.

No right turn on red

When posted, you must wait for a green light before turning right.

Left turn on red

Only allowed from a one-way street onto another one-way street, after a full stop.

Left turn from two-way street

Start from the left lane; end in the left lane of the cross street.

Right turn

Stay as close to the right curb as possible; end in the right lane.

U-turns

Legal where not prohibited by a sign; must not interfere with traffic. Illegal in Minnesota where signs prohibit it, where the maneuver cannot be completed safely, or in restricted areas. Minnesota treats improper U-turns as a moving violation.

4. Lane Rules & Bridge Speed Limits

Minnesotas handbook includes specific rules for bridge speed limits and the commercial vehicle following distance on rural highways, outside residential areas, trucks must not follow within 400 feet of one another except to pass. Heres the full lane breakdown:

Center turn lane (CTSL)

Used only to begin or complete a left turn; not for through travel or merging. You may travel no more than 300 feet in the CTSL.

Solid white line

Do not cross; marks the edge of the road or a lane that should not be changed.

Solid yellow line (your side)

No passing allowed.

Broken yellow line

Passing allowed when safe.

Solid + Broken yellow centerline

Passing allowed only on the broken-line side.

5. Passing: 10 MPH Over While Passing

Minnesota has a passing speed exception that is unique among US states: on two-lane highways with a posted limit of 55 mph or higher, you may exceed the limit by up to 10 mph while lawfully passing, but this does NOT apply in work zones or on bridges with special limits. Watch for No Passing signs on bridges:

• Only pass on the left, using the oncoming lane, when it is safe and legal.
• Do not pass within 100 feet of an intersection, railroad crossing, bridge, or curve where your view is limited. Look for the No Passing Zone pennant sign.
• The vehicle being passed must not speed up while you are overtaking.
• Return to your lane after confirming the pass is complete. Use your right turn signal before returning to the right lane, signaling is required on both the initiation and return of a pass.
• Never pass a stopped school bus with flashing red lights, this applies in both directions on undivided roads.
• You may pass on the right only when the vehicle ahead is turning left and there is a usable lane to the right.

6. Following Distance

Minnesotas handbook notes that on gravel or dirt roads, stopping takes much longer and skidding on turns is much easier than on pavement. The 3-second rule is your minimum on Minnesotas paved roads, on the gravel county roads and forest roads of northern Minnesota, add several more seconds.

7. School Buses & Emergency Vehicles

Minnesota adds a $25 surcharge to the speeding fine whenever you fail to slow down for a stopped emergency vehicle with flashing lights. School bus rules are also tested, on Minnesotas rural township roads, buses stop frequently at isolated farm driveways.

School Buses

• When a school bus stops with flashing red lights and an extended stop arm, all traffic in both directions must stop on undivided roads.
• On roads with a true median or physical barrier, only traffic behind the bus must stop, oncoming traffic may proceed.
• A center turn lane does not count as a divider. On 4+ lane roads without a raised median or barrier, all directions must stop.
• You must remain stopped until the red lights stop flashing and the stop arm is retracted.
• Illegally passing a Minnesota school bus carries significant fines and points on your driving record. You must stop at least 20 feet from the front of a stopped school bus with arm extended.
• Railroad crossings: School buses must stop at ALL railroad crossings, with or without passengers, even if no lights are flashing and no train is visible. This is a frequently tested rule.

Emergency Vehicles

• When you see or hear an emergency vehicle (police, fire, ambulance) with lights or siren: pull to the right edge of the road and stop. Do not block intersections.
• Move Over Law (Minnesota): You must slow down when approaching or passing a stopped emergency vehicle with emergency lights flashing. A surcharge of at least $25 is added to the speeding fine if you violate this law. On multi-lane roads, move one lane away when safely possible.

8. DWI Laws: 0.16% Enhanced Tier

Minnesotas DWI law has an enhanced penalty tier at 0.16% BAC, and at that level, aggravated consequences apply including plate impoundment and ignition interlock. Refusing a chemical test in Minnesota is now a crime, not just a civil penalty. Refusal triggers a 1-to-6-year revocation depending on prior offenses.

9. Seat Belts & Child Seat Matrix

Minnesota requires all occupants to be buckled. The child passenger restraint system uses a three-stage matrix by age, weight, and height, from rear-facing infant seat through booster seat to belt alone at age 8 or 49". The back seat is recommended for all children under 13.

10. Where You Cannot Park

Minnesotas parking rules include a specific mailbox prohibition, do not park in front of mailboxes, and a unique parking exit requirement: check for traffic, cyclists, and pedestrians before opening any door. Heres the full list of prohibited parking areas:

• Within 15 feet of a fire hydrant
• Within 20 feet of a crosswalk at an intersection
• Within 30 feet of a stop sign, yield sign, or traffic signal
• Within 50 feet of a railroad crossing
• On a sidewalk, in front of a driveway, or on a bridge
• In a no-parking zone or alongside a curb painted yellow or red
• Double parking (alongside a vehicle already parked at the curb)
• Headed downhill: turn wheels toward the curb. Headed uphill with a curb: turn wheels away from curb. Uphill without a curb: turn wheels toward the shoulder.

11. Driving in Bad Weather

Minnesota winters are severe, the Twin Cities average over 50 inches of snow, outstate Minnesota regularly sees 100+, and the North Shore of Lake Superior can close US-61 with lake-effect snow in a matter of hours. Minnesotas handbook notes that half of all crashes happen after dark. Heres what DVS requires:

• Headlights required in Minnesota at sunset until sunrise, in rain/snow/hail/sleet/fog, and whenever you cannot see the road ahead at 500 feet. Keep headlights on low beam in precipitation.
• In heavy fog, use low beams, high beams reflect off fog and reduce visibility.
• If you start to hydroplane, ease off the gas gently. Do not brake hard or turn sharply.
• In icy conditions, brake gently well in advance. Start slowing earlier than normal. Leave extra following distance.
• If your car goes into a skid, steer in the direction you want the front of the car to go. Do not overcorrect.
• Never use cruise control on wet, icy, or slippery roads.

12. Points: $680 DWI Reinstatement Fee

Minnesotas driver licensing system uses both administrative revocations (DWI-related) and a standard license suspension system for traffic violations. DWI revocations come with a $680 reinstatement fee and vary from 90 days to permanent cancellation based on offense number and severity. Heres how it works:

Note: Minnesota DWI revocations require a $680 reinstatement fee plus new license application, and may require enrollment in the Ignition Interlock Device Program. Criminal penalties are imposed separately from administrative sanctions. Each offense has unique criminal penalties depending on prior violations, criminal record, and circumstances of arrest.

13. Headlights: Dim at 1,000 Feet

Minnesotas headlight dimming distances are distinctive: 1,000 feet for oncoming vehicles and 200 feet when following, and the handbook explicitly warns not to "overdrive" headlights since high beams only illuminate 350 feet ahead. Minnesota also requires headlights in snow, rain, hail, sleet, and fog:

Key test point: Minnesota uses 1,000 feet for oncoming and 200 feet for following, both very different from the 500/300 that many other states use. This is a frequently missed question for people who studied another states manual. Also: high beams illuminate at most 350 feet in Minnesota, overdriving headlights on Minnesotas dark rural roads is specifically warned against in the handbook.

14. Night Driving

Minnesotas handbook explicitly uses the term "overdrive your headlights", it is a directly tested concept. High beams illuminate at most 350 feet; if you are driving fast enough that you cannot stop within 350 feet, you are overdriving. Half of all crashes in Minnesota happen after dark. And deer collisions peak in November, right when Minnesota clocks go back and roads get darker earlier.

15. Cell Phones: Zero Use on Provisional

Minnesota bans handheld device use while driving and has strict rules for drivers on provisional licenses and instruction permits, zero cell phone use of any kind. The handbook also emphasizes that increasing speed decreases your visual field, making distractions even more dangerous at higher speeds.

Key test point: Minnesotas instruction permit and provisional license holders may not use ANY cell phone while driving, including hands-free. This applies regardless of age. The DVS exam also tests the principle that increasing speed decreases your visual field, a science-based reason why distractions are especially dangerous at higher speeds.

16. Railroad Crossings

Minnesotas rail network, including BNSF, Union Pacific, and Canadian Pacific freight lines, crosses thousands of public roads. The DVS knowledge test covers exact stop distances and which vehicles must always stop at railroad crossings regardless of signals.

Key test point: Never drive around or under a lowered crossing gate, it is illegal and extremely dangerous. Wait until gates are fully raised and all tracks are clear.

17. How to Drive a Roundabout

Minnesota DVT has been installing roundabouts at intersections throughout the metro area, along US-212 and MN-5 corridors in the southwest, and at rural highway junctions. The DVS tests them directly. The rule that most drivers miss on the test: entering traffic must yield to vehicles already circulating inside, without exception.

Key test point: The most common wrong answer on roundabout questions is thinking you have right-of-way when entering. You never do, yield to traffic already inside.
