Here's some trivia for you – did you know (as of 2017), only six states require seat belts on school buses? This may seem unsafe, but let's look at the facts. According to the American School Bus Council, children are about 70 times more likely to get to school safely if they take the school bus, instead of traveling by car.
However, many organizations endorse the use of seat belts in buses, including The National Safety Council and The American Academy of Pediatrics. Although the National Highway Safety Traffic Administration (NHTSA) agrees that school buses are safe, they also believe that three-point restraint systems can make school buses even safer.
Child safety restraint systems are national mandates on buses when the bus weighs less than 10,000 pounds. These buses require a shoulder/lap belt. However, such buses comprise only about 20% of the nation's school bus fleet. The large school buses should have a Child Safety Restraint System (CSRS) if the state or district requires them – but it's not federally mandated.
