North Dakota Booster Seat Law (2026)

North Dakota is upgraded to an official-source page because NDDOT's Vision Zero site gives an unusually clean version of the rule and the penalty.

For 2026 checks, the direct answer is: under 8 in a car seat or booster unless at least 57 inches tall; ages 8 through 17 in a child restraint or seat belt; $25 fee, no points.

NDDOT also recommends keeping a child in a booster until 4'9" regardless of age, and in the back seat until 13.

The statute uses age 8 as the line and leaves the choice between car seat and booster to the seat manufacturer's instructions. A 4-year-old who still fits a forward-facing harness is correctly restrained in it; a 6-year-old who has outgrown the harness moves to a booster. Both satisfy 39-21-41.2.

Ages 8 through 17 are covered by the same section: an approved child restraint or a seat belt. In practice most children this age ride with the seat belt, and the safety question is whether it fits.

57 inches is 4 feet 9 inches, the same benchmark used in Texas, California, and Oklahoma. In North Dakota it works as an exception to the under-8 rule: a child who reaches 57 inches before turning 8 may use the seat belt. Note the wording "at least" — exactly 57 inches qualifies.

Height is a proxy for belt fit, not a guarantee. Check the lap belt sits low on the thighs and the shoulder belt crosses the middle of the shoulder and chest in the exact seating position the child uses.

The statute exempts vehicles that were manufactured without seat belts and situations where a child is being transported in an emergency. It also says a violation is not, by itself, evidence of negligence and is not admissible in other proceedings.

A family car, pickup, or SUV is covered. If you rely on an exemption, read the statute text rather than a summary.

A violation of North Dakota Century Code 39-21-41.2 carries a $25 fee and no points on the driver's license, according to the North Dakota Highway Patrol classification of offenses and NDDOT Vision Zero.

North Dakota's $25 fee with no points is among the lightest penalties in the country. The North Dakota Highway Patrol's classification of offenses lists the child restraint violation as a non-point offense, and NDDOT's public guidance gives the same $25 figure.

No. Century Code 39-21-41.2 is a child restraint section for children under 18. A viral notice claiming North Dakota requires adults under a certain height to use booster seats is not this law; see the adult booster seat law fact check. Searches using the phrase "adult booster seat" usually mean the point when a child can move from a booster to the adult seat belt.
