Because seat-belt use is more common in more heavily populated counties, outweighing lesser use in rural counties, Kentucky's statewide seat-belt use rate in 2014 was approximately the national average. However, the CDC says the state's traffic-death rate is much higher than the national average. According to the Kentucky State Police, about two-thirds of people killed in traffic accidents in the state were not using a seat belt.
Kentucky's seat-belt law requires the driver and all passengers to use seat belts, unless the passenger is a child less than 40 inches tall, in which case a child restraint system must be used. Children younger than 7 and between 40 and 50 inches must be in a booster seat, which uses a seat belt.
