Seatbelt laws are in place for a good reason. According to the Missouri Traffic Safety Compendium, in 2022, drivers and passengers
who did not use a seat belt or other restraint accounted for:

• 35 percent of all “disabling injuries”
• 21 percent of all “evident injuries”
• 62 percent of all fatal injuries
• 66 percent of all people partially or totally ejected from a vehicle

Missouri’s Seat Belt Laws

The state’s seat belt laws can be found in Missouri Revised Statute §301.178 and
Missouri Revised Statute §301.179, and they mostly concern children. In general,
they are:

• Everyone riding in the front seat of a vehicle weighing less than 12,000 pounds (so, a passenger car) must wear
  a seatbelt that meets National Highway, Transportation and Safety Act
  requirements. An exception exists for vehicles manufactured before January 1, 1968.
• Exceptions may also apply to people who have medical reasons not to wear a seatbelt (with a doctor’s note).
• Anyone under the age 18 operating or riding in a truck must wear a seatbelt.
• Driver’s transporting children under the age of 16 must ensure that they are all wearing a seatbelt, and that:
  • Any child under two years old should be secured in a rear-facing child safety seat.
  • Any child under the age of four must be secured in an approved child safety seat.
  • Any child less than 40 pounds, regardless of age, must be secured in an approved child safety seat.
  • Children between the ages of four and eight, weighing between 40 and 80 pounds and who are less than 4
    foot 9 inches, must be in a child booster seat.
• Police cannot pull you over only to ensure you’re wearing a seat belt, and it’s not probable cause for
  any other crime.
• “Public carriers,” like taxis or buses, are exempt from seatbelt laws. Children also do not have to wear seat
  belts on school buses designed to carry 11 passengers or more.
• Post office drivers and drivers of agricultural vehicles are also exempt.

What Are the Penalties for Violating Missouri’s Seat Belt Laws

It’s the driver’s responsibility to ensure everyone in their vehicle is following the law. If a driver or a passenger
is not wearing or using their seat belt correctly, the driver may have to pay a fine between $10 and $50 and
additional court costs. If the violation was for not having a child in an appropriate child safety seat, you can
avoid the conviction by showing the court that the problem has been remedied since you got ticket.

Drivers of vehicles with unsecured children may face criminal negligence charges if the child is injured or killed.
And there’s good reason for that. In Missouri in 2017, of the 79 children killed in car accident, 55 were not wearing a restraint during the time of the crash.

Can I Still Get Compensation in a Missouri Car Accident If I Wasn’t Wearing a Seatbelt?

Yes, you can still make a financial recovery if you were not wearing a seatbelt when you were injured by a negligent
driver. Missouri is one of 15 states that allow a seat belt defense in personal injury cases, with two stipulations:

1. The defense must present an expert witness who can testify
   that your failure to wear a seat belt contributed to your injuries.
2. Your compensation can’t be reduced by more than one percent of your total damages.

Missouri is a comparative negligence state, meaning you
only receive compensation for that percentage of the accident that wasn’t your fault. In the above case, say
your damages amount to $100,000. If you weren’t wearing a seat belt, you would still have a right to $99,000 in
damages.

The Importance of Buckling Up and Benefits of Missouri Seat Belt Laws

The National Highway Traffic Safety Administration (NHTSA) reports that more than half of the people who died in recent vehicle accidents were not wearing seat belts. In Missouri, specific rules govern seat belt usage, and they help keep you and your loved ones safe on the roads. 

Why is it so crucial to buckle up? The statistics speak for themselves:

• In Missouri, about two-thirds of those killed in crashes were not wearing seat belts. Wearing one is a form of defense against the risk of injury. 
• Wearing a seat belt reduces the risk of death by 45% for front-seat passengers.
• Seat belts prevent occupants from being ejected from the vehicle during a crash, a situation that often results in severe injuries or death. 
• Missouri requires you as the driver and passengers to wear a seat belt, and buckling up can prevent you from having to pay a fine and other court costs. 
• In one year alone, $70 billion was lost through medical and lost work productivity after crash deaths and injuries. Seat belts help reduce these losses.

Exceptions and Special Cases

While Missouri’s seat belt law applies to most drivers and passengers, there are a few exceptions:

• Individuals with a qualifying medical condition that prevents them from wearing a seat belt may be exempted with a written statement from a physician.
• Mail carriers are not required to buckle up
• Passengers in vehicles built before January 1, 1968, are not required to wear seat belts, as these vehicles were manufactured without seat belt equipment.
• Agricultural workers do not have to wear seat belt when in work vehicles and in private property 

However, it’s important to note that these exceptions are limited, and wearing a seat belt is always the safer choice whenever possible.

Leading by Example

As adults, it’s our responsibility to set a good example for younger generations. Children often learn best through observation, and if they see adults consistently wearing seat belts, they’re more likely to develop this life-saving habit themselves.

Seat belt laws are in place for a reason – to keep us all safe on the roads. In Missouri, the law ensures that everyone takes seat belt usage seriously. 

You Can Still Suffer Injuries While Wearing a Seat Belt

While wearing a seat belt is undoubtedly one of the most effective ways to protect yourself in a car accident, always remember that even with your seat belt on, you can still suffer injuries in a crash.

Seat belts are designed to distribute the force of impact over a larger area of your body, minimizing the risk of serious injury. They are particularly effective in preventing ejection from the vehicle, which can be catastrophic. However, they cannot completely eliminate the potential for injuries.

In a violent collision, your body can still experience significant forces, even with the protection of a seat belt. These forces can result in various injuries, including fractures, internal injuries, and soft tissue damage. It’s important to seek medical attention after an accident, even if you don’t immediately feel pain, as some injuries may take time to manifest.
