looks like the kids are all ok, also looks like the driver of the second bus did the best they could to avoid more injuries by driving off the road into the field...
judging by the type of buses in the incident, they hold around 70-85 people per bus. now this is 3 kids to a seat plus the driver. if the kids are unable to help them selves in a major accident... i dont know.. say the bus is on fire and the driver is the only one able to help them because they kids are stuck in seat belts... how many kids will die?
in everything we are taught,told,shown buses give you about 2 minutes to get out before the fumes/flames/gasses take over. 2 minutes is not enough time to get a fully loaded bus evacuated.
It is in my belief that seat belts on large buses are a bad idea.
Also if a student does not want to wear one, they can become an object that can inflict harm towards other students by hitting them with the buckle. More stuff to distract a bus driver.
