It is now mandatory(强制) for drivers or passengers to wear seatbelts while in a car in all states. In addition, it is also mandatory for kids of be in some kind of specialized car seat. Given the strict requirements in other vehicles, why don't buses have seatbelts?
The main answer, at least for school buses, is that seatbelts do not make school buses safer. Overall, traveling on school buses is the safest way to travel—40 times safer than riding in a car—with only a handful of deaths occurring to passengers on school buses every year. The seats on the school bus are placed very close to each other and have high backs that are thickly padded. As a result, in an accident the students would be propelled forward a very short distance into a padded seatback that in a way is like an airbag. In addition, the fact that people sit high off the ground on school buses also makes it safer to travel on them.
While school buses feature high backed seats and elevated seating locations, the same cannot be said of city buses. However, from a practical angle, there's little need to require seatbelts on city buses. Although the design of the modern low—floor city bus is less safe than the design of school buses, the fact that city buses rarely travel at speeds greater than 35 miles per hour means that any collision is likely to be small, Also, given that most trips on city buses are short and that many trips have standing passengers, the presence of seatbelts will make even less of a difference.
Another answer why buses do not have seatbelts is cost. It is estimated that adding seatbelts to buses would add between $8,000 and $15,000 to the cost of each bus. In addition, seatbelts would take up room currently used as seats, meaning that each bus would have fewer seating places. The additional room in the bus taken up by seatbelts would mean that bus fleets would have to increase by as much as 15% just to carry the same number of people. Such an increase would be especially difficult in cities that experience overcrowding on their vehicles.
Regardless of whether their passengers have seatbelts, all buses provide seatbelts for drivers and most bus companies make their drivers wear seatbelts in order not to be influenced by a collision.
