Driving in Minnesota 2026 — Winter Driving Laws & -40°F Road Rules

Driving in Minnesota

Driving in Minnesota (MN) means navigating one of the coldest states — subzero winters and heavy snowfall. The state capital is Saint Paul, and the road network ranges from busy urban freeways to remote rural two-lanes. Handheld phone use behind the wheel is banned.

Speed Limits in Minnesota

Rural interstates posted at 70 mph. Urban interstates around Minneapolis-St. Paul posted at 55 mph.

School zones in Minnesota drop to 15-25 mph when children are present, and construction zones often carry doubled fines. Watch for posted signs — local limits can vary from the defaults.

Traffic Laws in Minnesota

Cell Phone Law: Hands-free required for all drivers. Handheld use prohibited while driving. Fines for violations in Minnesota can be substantial, and points may be added to your licence.

Seatbelt Law: Primary enforcement for all occupants. Both drivers and all passengers must be belted in Minnesota.

Right Turn on Red: Permitted in Minnesota after a complete stop, unless a sign says otherwise. Yield to pedestrians and cross traffic.

Move-Over Law: When you see emergency vehicles stopped with flashing lights in Minnesota, move over one lane or slow down significantly.

Headlights: Required from sunset to sunrise and at any other time when visibility is impaired by weather, smoke, fog, or other conditions.

Child Restraints: Children under 8 must be in a child restraint system unless they are 4 feet 9 inches or taller. Children 8 and older must use a seatbelt.

DUI Laws in Minnesota

The legal BAC limit in Minnesota is 0.08% for drivers 21 and over. For under-21 drivers, Minnesota enforces zero tolerance — any detectable alcohol is illegal. Commercial vehicle drivers face a nationwide 0.04% limit.

First-time DUI penalties in Minnesota include fines, potential jail time, mandatory alcohol education, and licence suspension. Repeat offenders face escalating consequences including ignition interlock devices and extended licence revocation.

Tyre Requirements in Minnesota

Minnesota does not mandate winter tyres, but appropriate tyres for the conditions are always your responsibility. Chains are not permitted on paved highways unless the road surface is completely covered with ice or snow.

Studded Tyres: Prohibited year-round.

Tread Depth: Minnesota enforces the federal minimum of 0.0625 inches (2/32"). At this depth, wet braking performance is severely compromised. Replace tyres at 4/32" — do not wait for the legal limit.

For Minnesota’s winters, tyres rated M+S or bearing the 3PMSF snowflake symbol provide measurably better cold-weather grip than summer tyres.

Insurance and Equipment in Minnesota

Minnesota requires all drivers to carry liability insurance. Keep proof in your vehicle. If you are stopped without it, penalties include fines and possible licence suspension.

Your vehicle in Minnesota must have working headlights, brake lights, indicators, mirrors, horn, and wipers. Registration and plates must be current. Window tint regulations vary — verify MN limits before tinting.

Licence Requirements for Visitors to Minnesota

A valid licence from your home state or country is accepted for driving in Minnesota. International visitors are strongly advised to carry an IDP alongside their national licence. Rental agencies and police in Minnesota may request both.

New residents of Minnesota must get a state licence after establishing residency. Requirements usually include a vision screening, a written test on Minnesota’s traffic laws, and possibly a behind-the-wheel exam.

Toll Roads in Minnesota

Toll facilities in Minnesota increasingly use cashless electronic tolling. Rental cars may come with a transponder option, but the daily fee adds up quickly. Consider getting your own transponder if driving extensively in Minnesota.

Seasonal Driving in Minnesota

The one of the coldest states — subzero winters and heavy snowfall in Minnesota means road conditions change with the seasons.

Seasonal preparation for Minnesota:

• Winter: carry an ice scraper, snow brush, jumper cables, and a bag of sand or cat litter for traction. Keep an emergency blanket and extra warm layers in the vehicle
• Summer: check tyre pressure and coolant levels before long drives
• Year-round: keep an emergency kit with water, torch, phone charger, first aid, and snacks
• Check Minnesota’s DOT website for real-time road conditions and travel advisories

Renting a Car in Minnesota

Most rental agencies in Minnesota require drivers to be at least 21. Under-25 surcharges are standard. If you hold a foreign licence, bring your IDP and confirm acceptance when booking.

Before leaving the lot in Minnesota, photograph any existing damage, test the lights, wipers, and horn, and verify that the spare tyre and jack are present. Check the fuel policy — most agencies expect a full tank on return.

Your existing insurance or credit card may cover rental vehicles in Minnesota — verify before declining the agency’s coverage. International visitors should strongly consider full coverage.

Emergency Contacts in Minnesota

Dial 911 for any emergency in Minnesota — police, fire, or medical. For non-emergency roadside assistance, contact the Minnesota State Patrol at (651) 201-7100.

If you are in an accident in Minnesota: stop immediately, check for injuries, call 911 if anyone is hurt, move vehicles to the shoulder if safe, exchange insurance and contact details, and photograph the scene. Do not admit fault.

If your car breaks down in Minnesota, pull off the road as far as safely possible, activate hazard lights, and set up reflective triangles if you have them. Stay in your vehicle on busy highways and call for assistance.
