In general， parents and lawmakers alike seem pretty content to let children take school buses every day without giving much thought to the fact that those same kids would be firmly buckled up if they were riding in a car. In fact， for many of the younger and smaller kids， regular seat belts wouldnt even be sufficient in a car. Theyd have to have the additional protection of a car seat.

Todays school buses have been designed for better crash and rollover protection. They protect kids through “compartmentalization” which means spacing seats close together， as well as using seats with high and energy?absorbing backs to prevent children from being tossed around in a collision.

Unfortunately， though， deadly school bus crashes happened. Such was the case in November 2016 when a crash in Chattanooga， Tennessee killed six elementary school students. After another deadly school bus crash in May 2018 in Morris County， New Jersey， killed two including a child， and injured 43 others， the National Transportation Safety Board（NTSB） opened a full investigation into school bus safety.

The NTSBs report concluded that to provide the best protection for all students of large school buses， the remaining step is for each state to require the seat belts in all new large school buses.

But today seat belts are only federally mandated on small school buses， or those weighing 10，000 pounds（4，535 kilograms） or less. Currently only eight states have laws requiring seat belts on large school buses， though many others are considering similar legislation.

The number of lives that could be saved every year wouldnt be huge， and some opponents say adding belts is simply not worth the cost， which is estimated to be between $7，000 and $11，000 per bus.

Since most school buses are on the road for at least 10 and often up to 20 years， its unlikely schools would choose to update older buses at that cost， which means it would potentially take decades for new legislation requiring seat belts to take effect as new buses slowly replace older ones.

As for now， its unclear whether federal standards will change， but states are still free to set tougher restrictions as they see fit.
