Minnesota has zero tolerance for underage drinking and driving, strict rules for commercial drivers, and clear limits on where alcohol and cannabis may be kept in a vehicle.

Know the rule

The legal age to buy and drink alcohol in Minnesota is 21. It's illegal for anyone under 21 to drive with any detectable amount of alcohol.

You lose a CDL for at least one year on a first offense if you:

  • Drive a commercial vehicle at 0.04 or more
  • Drive any vehicle at 0.08 or more
  • Refuse a blood, breath or urine test while driving any vehicle
  • Are under the influence of a controlled substance
  • Leave the scene of a crash involving a vehicle you were driving
  • Use any motor vehicle to commit a felony
Handbook p. 98 ↗

Know the rule

A commercial driver with a detectable level under 0.04 is put out of service for 24 hours. An offense in a hazmat-placarded vehicle means losing the CDL for at least three years; a second offense means losing it permanently, as does using a commercial vehicle for a drug felony. CDL holders arrested for DWI in a passenger vehicle get no commercial work permit during the withdrawal.

Cannabis and hemp products in a private vehicle on a street or highway

  • Illegal if the package has been opened or the seal broken
  • Illegal if part of the contents has been removed
  • Allowed in the trunk, or where there's no trunk, an area not normally occupied by people
  • Not allowed in the glove compartment or utility compartment
  • An owner who isn't in the vehicle may not keep or allow opened products in it either
Handbook p. 99 ↗

Know the rule

You may not drink or have an open container of any alcoholic beverage inside a vehicle on a public street or highway, and it's unlawful to let a passenger drink or have one.

Handbook p. 99 ↗

Know the rule

You must not use, possess or sell controlled substances in a motor vehicle.

Handbook p. 99 ↗

Put it into practice

After a party, you have an opened bag of hemp gummies. Put it in the trunk before driving — not the glove box or utility compartment, and not in your passenger's lap.
