Booster Seat Law (Children) in Nevada

The specifics in Nevada

Children under 6 AND under 60 lbs must use booster.

Nevada Revised Statutes 484B.157 requires booster use until age 6 AND 60 lbs — a "both required" threshold. The Nevada Department of Public Safety's Office of Traffic Safety partners with the Nevada Highway Patrol and Sunrise Children's Hospital and Renown Children's Hospital for free CPST inspections. Primary offense; fines around $100.

What Booster Seat Law (Children) actually is

Every US state requires children to use a booster seat or appropriate child restraint past the toddler years, but the specific age, height, and weight thresholds at which booster requirements end vary widely by state. Boosters lift the child up so the vehicle's lap belt sits across the upper thighs (not the soft belly) and the shoulder belt crosses the collarbone (not the neck). Without a booster, a regular adult seatbelt sits in the wrong place on a small body and dramatically raises the risk of internal injury in a crash.

The American Academy of Pediatrics recommends children stay in a booster until they reach 4 feet 9 inches tall (around 57 inches) AND they pass the "5-step test" — knees bend at the seat edge, back is flat against the seatback, lap belt low across hips, shoulder belt mid-chest, child can sit still the whole ride. Most children don't pass that test until they're 10 to 12 years old, which is much older than most state laws require. State laws are the legal minimum; the AAP guideline is the safety standard. There's a real gap between the two.

Booster laws differ in three ways: the age threshold (varies from 5 to 9 across states), the height threshold (often 4 ft 9 in / 57 inches), and the weight threshold (usually 60 to 80 lbs). Some states use AND (must meet all three to graduate); some use OR (any one triggers graduation); the strictest states combine them. Enforcement varies — most states make it a primary offense (officer can pull you over just for this), some make it secondary (only if pulled over for something else). Fines run from $25 to $500. Many states offer free or discounted car seat fittings through fire departments or hospitals.

How to claim or invoke this right

To pick the right booster, start by checking your state's specific threshold (this page covers your state below). If your child meets the state law floor but not the AAP guideline, lean toward the AAP guideline — they're not the same and the law is the floor. Have your booster checked by a Child Passenger Safety Technician (CPST) for free at most fire stations or through Safe Kids Worldwide. For older kids who insist they're "too big for a booster," frame it around height and seatbelt fit, not age. Boosters are required in the back seat for almost all young kids; check your state's specific airbag rules for the front.

Common misconceptions

• "My state lets my 6-year-old out of a booster" doesn't mean it's safe — state laws are legal minimums, not safety recommendations.
• Backless boosters are legal in every state but high-back boosters give better head and side-impact protection and are preferred for younger riders.
• A booster on top of a seatbelt does not work — boosters must be used WITH the vehicle's lap-and-shoulder belt, never just a lap belt.
• Children should remain in the back seat until age 13 according to AAP, regardless of booster graduation.
• Carpool and rideshare drivers can be cited if a child rides without a required booster — the law applies to the vehicle, not just the parent.

Questions to ask

• What's the exact state threshold for graduating from a booster?
• Does my child pass the 5-step seatbelt fit test in our specific vehicle?
• Where do I find a Child Passenger Safety Technician for a free check?
• Are there exceptions for taxis, ride-shares, or out-of-state travel?
• When does my child legally qualify to ride in the front seat?
