Minnesota car seat laws are intended to help ensure that children are able to be protected as much as possible during a vehicle crash. Booster seat laws are integral for every child, but regulations vary state by state. While some states may enforce a booster seat age requirement, others may use a height requirement instead.

Car Seat Installation Information

Minnesota car seat rules also include properly installing a cat seat within a vehicle. The safety that a child’s car seat provides will be null if the seat is not properly installed. The National Highway Traffic Safety Administration (NHTSA) provides a few handy tips when it comes to proper car seat installation techniques:

  • Choose a seat that is based on your child’s size and age.
  • Make sure to read the manufacturer’s instructions first as every seat will have a different set of instructions to follow.
  • Use a car seat every time you drive with your child—no exceptions.
  • Refer to the vehicle manufacturer’s instructions, too, not just the seat manufacturer’s.
  • Check weight and height limits for each car seat.
  • A child should always be in a car seat until the age or height limits are met.

After a driver installs a car seat in a vehicle, he or she has the option to have the seat reviewed by a NHTSA technician. Car seat inspection stations are located throughout Minnesota in order for a certified technician to inspect the seat free of charge.
