Seat belt laws by state: back seats, enforcement, fines and exemptions
Which seats your state's belt law covers, how it is enforced and what a ticket costs
Picture 4 adults carpooling from Pennsylvania to a game in New York. In Pennsylvania, the adult belt law covers only the front seat. Police cannot stop a car for it alone. In New York, every rider 16 and older must buckle up in any seat. Officers can stop a car for a missing belt [1, 6].
The crash forces in that car do not change at the border. Neither does the toll of skipping a belt. In 2024, 9,758 people who died in passenger vehicles were unbuckled, according to the National Highway Traffic Safety Administration (NHTSA). That was 48% of those whose belt use was known [5].
This guide explains what state belt laws cover, groups the states by type, and shows how penalties and exemptions work. It also covers what the research says and how to check your own state’s law in 5 minutes. For why belts work and how to wear one, see our seat belt safety guide.
The five questions every belt law answers
Occupant protection policy specialists read a belt law by asking five questions. Two states that both have a belt law can answer them very differently.
- Who is covered? Most laws cover drivers and passengers above a set age. Younger riders usually fall under a separate child passenger law.
- Which seats? Some laws cover only the front seat. Others cover every seating position.
- How is it enforced? Under primary enforcement, an officer can stop and ticket you just for not buckling. Under secondary enforcement, a belt ticket can only follow a stop for some other violation [2].
- Who gets the ticket? Many laws cite adults for their own belt and make the driver answer for minors. In New York, for example, the driver is responsible for passengers under 16 [6].
- Who is exempt, and what does it cost? Each law lists exceptions and penalties, covered below.
Federal motor carrier rules add a layer for commercial trucks and buses: the driver must wear a belt where one is installed. In property carrying trucks, every other occupant with a belt must use it too [7].
Front seats: primary, secondary or none
Both major trackers agree on the front seat count. IIHS and GHSA list 35 states plus DC with primary enforcement and 14 states with secondary enforcement [1, 2]. New Hampshire is the only state without a belt law for adults, though its child passenger law still applies to younger riders [2]. The IIHS table shows that law covering riders through age 17 [1].
Secondary does not mean optional. Not buckling is still against the law in those states, but it cannot be the only reason for a stop.
Several secondary law states treat young riders differently. The IIHS table shows primary enforcement for riders younger than 16 in Missouri and younger than 18 in Pennsylvania [1].
Back seats: the biggest gap between states
Rear seat coverage varies far more than front seat rules. So does behavior: in 2025, 91.3% of front seat riders buckled, versus 84.0% in back [4]. NHTSA lists 33 states plus DC that required adults to buckle in every seat as of June 2, 2025 [4]. Virginia’s rule for adult rear passengers took effect July 1, 2025, bringing the total to 34 states plus DC, which matches the IIHS count [2, 3].
Enforcement in the back seat varies too. NHTSA names 12 states where rear seat rules are secondary only. Virginia’s law is also secondary [4, 8]. That leaves 21 states plus DC where, by our count, police can stop a car for an unbuckled adult in back.
GHSA counts differently, listing 18 states plus DC with primary enforcement for all occupants. It also counts 42 states plus DC with some rear seat rule, including rules that cover only children or teens [2]. When trackers disagree, the statute itself is the tiebreaker.

Where the states stand for adult riders (Drive With Care grouping)
| Front seat enforcement | Adults in back: primary | Adults in back: secondary | Adults in back: not covered |
|---|---|---|---|
| Primary (35 states + DC) | Alaska, California, Delaware, DC, Hawaii, Illinois, Indiana, Kentucky, Louisiana, Maine, Minnesota, Mississippi, New Mexico, New York, North Dakota, Oregon, Rhode Island, South Carolina, Texas, Utah, Washington, Wisconsin | Alabama, Connecticut, Kansas, Maryland, New Jersey, North Carolina | Arkansas, Florida, Georgia, Iowa, Michigan, Oklahoma, Tennessee, West Virginia |
| Secondary (14 states) | None | Idaho, Massachusetts, Montana, Nevada, Vermont, Virginia, Wyoming | Arizona, Colorado, Missouri, Nebraska, Ohio, Pennsylvania, South Dakota |
| No adult law | None | None | New Hampshire |
Built from the IIHS table (October 2026) and NHTSA’s list of rear seat laws (as of June 2, 2025), updated for Virginia’s July 2025 change [1, 4, 8]. Some states in the last column still require children or teens to buckle in back.
Does rear coverage matter? In 2025, rear seat belt use was 86.3% in states requiring belts in all seats, versus 78.0% in front seat only states [4].
Age rules: where child seat laws hand off to belt laws
Age is where state laws get tangled. In the IIHS table, the youngest age a belt law covers ranges from 6 in Florida and Nevada to 18 in 12 states [1].
In 26 states plus DC, the belt law starts at 16 or 18. There, the child passenger law covers younger riders, often requiring a belt through age 15 or 17 after the booster stage [1].
The car seat and booster stage also ends at different points. Florida’s and Arkansas’s requirements end after age 5. Louisiana, Minnesota and Tennessee can require a booster through age 8 [1]. Some states add a height cutoff, often 57 inches (4 feet 9 inches).
Watch for coverage gaps. Florida’s belt law covers riders 6 to 17 in every seat but adults only in front [1]. So a teen in the back may be covered while the adult beside them is not. Our child passenger safety laws guide covers the car seat rules in depth.
Pickup beds and cargo areas
According to IIHS, adults may legally ride in an open pickup bed in most states, even though the bed offers no crash protection. A sudden steering move to dodge something can throw a rider out, even at modest speed. IIHS counts 30 states plus DC with cargo area riding laws. Most of them limit children. Exceptions are common [3].
Two official examples show how different these rules can be:
- Virginia bars anyone under 16 from riding in a pickup’s rear cargo area on its highways. It exempts authorized parades and farm trips between fields [9].
- California’s driver handbook tells drivers not to let anyone ride in the back of a truck without secure seats and belts [10].
In 2024, 59% of pickup truck occupants killed were unbelted [11]. Treat every cargo area, including van floors and SUV cargo spaces, as off limits to people.
Exemptions: who a belt law may excuse
Exemptions are narrow. Some require paperwork. Two official sources show what they look like.
Virginia exempts people with a signed physician’s statement, which must be carried on the person or in the vehicle [8]. It also excuses rural mail carriers and newspaper carriers on their routes, and taxi drivers and their passengers. Collection and delivery crews whose work means leaving the cab very often are excused too [8].
New York exempts certain emergency vehicles and vehicles made in 1964 or earlier. It also excuses bus passengers (school buses aside), rural letter carriers on duty, and people a physician certifies cannot be restrained [6].
A traffic safety attorney would add two cautions. Job based exemptions apply only while doing that job, such as delivering mail, not on the drive home [6, 8]. And if a health condition makes the belt painful, ask your clinician about fit solutions before assuming you qualify.
Penalties: what a belt ticket can cost
Belt fines are usually modest, but the details vary.
Comparison compiled by Safety Behind the Wheel Foundation
Examples of belt penalties (check current amounts before relying on them)
| State | What the official or tracker source shows |
|---|---|
| Washington | $250 maximum base fine, the highest in the IIHS table [1] |
| Virginia | $25 civil penalty, no license points, no court costs [8] |
| New York | Up to $50 for an adult’s own belt; $25 to $100 plus 3 points per unbuckled passenger under 16 [6] |
| Massachusetts | $25 for the driver’s own belt, plus $25 for each unbuckled passenger ages 12 to 15 [1] |
| North Carolina | $25.50 for a front seat violation, $10 for the rear seat [1] |
| Kansas | $60 for riders 14 to 17, $30 for adults 18 and older [1] |
The IIHS table lists maximum base fines from $10 to $250 and notes that fees may add to the total. It flags DC, Illinois and New Mexico among places that assess license points [1]. Wyoming rewards belt use instead, cutting $10 from fines for other violations when you are buckled [1].
The ticket may not be the biggest legal issue, because belt use can come up in an injury claim after a crash. Virginia’s statute bars using a belt violation as evidence of negligence or to reduce damages in such cases [8]. Other states may treat it differently, so ask a licensed attorney in your state about a specific case.
Do stronger laws work? What the research shows
NHTSA’s Countermeasures That Work guide (11th edition, 2023) gives primary enforcement laws 5 stars, its highest rating. Short term, high visibility belt enforcement also earns 5 stars. Higher fines earn 4 stars [12].
The belt use gap between law types has narrowed. In 2004, use was 84% in primary law states versus 73% in secondary law states [13]. By 2025, it was 92% versus 89% [3].
IIHS reports that both types of law reduce deaths, but primary laws do more. Estimates of their extra effect on deaths range from 3% to 14%, though newer studies find smaller effects than older ones [3]. Fines matter too: one research team linked raising fines from $25 to $100 with belt use 6 to 7 percentage points higher [3].
The Centers for Disease Control and Prevention (CDC) notes that belt laws do the most good when they apply to every seating position [14]. The national Click It or Ticket campaign pairs extra enforcement with advertising, with a Thanksgiving wave set for November 23 to 29, 2026 [11].
Legal minimum vs. best practice
Occupant protection specialists measure success by how people ride, not by tickets.
Comparison compiled by Safety Behind the Wheel Foundation
| Topic | Where the legal minimum can fall short | Best practice |
|---|---|---|
| Adults in back | No adult rear seat rule in 15 states, and no adult law at all in New Hampshire [1] | Everyone buckles, every seat, every trip |
| Enforcement | Adult belt tickets only after another violation in 14 states [1] | Buckle whether or not police can stop you for it |
| Belt fit | Laws set when a belt must be worn | Lap belt low on the hips, shoulder belt across the middle of the chest, never behind the back or under an arm [15] |
| Pregnancy | Where a medical exemption exists, it may require a physician’s signed statement [8] | Doctors recommend buckling through pregnancy: lap belt below the belly, shoulder belt between the breasts [15] |
| Children | Booster rules can end after age 5 [1] | Booster until the adult belt fits, usually ages 8 to 12; back seat until 13 [15] |
| Sharing belts | New York, for one, requires one person per belt [6] | One person per belt; never a child on a lap |
| Pickup beds | Adults may ride there in most states [3] | No one rides in a cargo area |

What your state's belt law covers
Use this checklist when you read your state’s statute or driver manual.
How to verify your state's law in 5 minutes
- Minute 1: Get the national picture. Open the IIHS seat belt law table and the GHSA seat belt page. Note each one’s date.
- Minute 2: Go to the state source. Find your highway safety office in GHSA’s directory or your licensing agency through USA.gov.
- Minute 3: Read the statute. On your legislature’s website, check the belt section’s age, seat and enforcement wording, then its list of exceptions.
- Minute 4: Check the penalty. Look for the fine, points and court costs, plus any separate rule for minors.
- Minute 5: Check the date. Compare the statute’s history line with the tracker’s date. Virginia’s adult rear seat rule, for example, took effect July 1, 2025, after NHTSA’s June 2025 list [4, 8].
Frequently asked questions
Is it illegal not to wear a seat belt in the back seat?
It depends on your age and state. Laws in 34 states plus DC require adults to buckle in back [1]. GHSA counts 42 states plus DC with some rear seat rule, often for children and teens [2]. Buckling up in back is always the safer choice.
Which states have secondary seat belt laws?
IIHS and GHSA list 14: Arizona, Colorado, Idaho, Massachusetts, Missouri, Montana, Nebraska, Nevada, Ohio, Pennsylvania, South Dakota, Vermont, Virginia and Wyoming [1, 2]. Some of them use primary enforcement for younger riders.
Does New Hampshire have a seat belt law?
Not for adults. New Hampshire is the only state with no adult belt law. But its child passenger law still covers younger riders [1, 2].
Can police pull you over just for not wearing a seat belt?
Yes, for a front seat violation in the 35 states plus DC with primary enforcement, though rear seat rules may differ [1]. In secondary law states, a belt ticket can only be added after a stop for another violation [2].
Who gets the ticket if a passenger isn’t buckled?
Rules vary by state. In New York, adult passengers can be fined for their own belt. Drivers face a fine and 3 license points for each unbuckled passenger under 16 [6]. Massachusetts also fines drivers for unbuckled passengers ages 12 to 15 [1].
Is it legal to ride in the bed of a pickup truck?
IIHS says most states allow adults to ride there. It counts 30 states plus DC with laws mostly aimed at children [3]. Legal or not, a pickup bed offers no crash protection.
The bottom line
Recommendation from Safety Behind the Wheel Foundation
State belt laws differ on back seats, enforcement and age, but crash physics does not. Know your state’s rules. Follow a simpler one everywhere: everyone buckled, every seat, every trip.
