Why Does a Bus Tip Over?
A bus tips over when its center of gravity shifts outside its base of support. This can happen during sharp turns, sudden lane changes, or when the vehicle hits a curb or soft shoulder. High center of gravity, uneven passenger weight, and excessive speed increase rollover risk. According to the National Highway Traffic Safety Administration, rollover crashes are a leading cause of fatal bus accidents.
Common Causes of Bus Rollovers
Driver error, including distracted or fatigued driving, is a frequent cause. Speeding on curved roads and abrupt steering corrections can destabilize the vehicle. Mechanical failures such as tire blowouts or brake issues also contribute. Overloading the bus or placing heavy luggage on the roof raises the center of gravity and makes tipping more likely.
What to Do After a Bus Rollover
Stay seated and brace yourself if the bus begins to tip. Once the vehicle stops, follow the driver’s instructions and exit carefully. Check yourself and others for injuries, and call emergency services immediately. Document the scene with photos if you are able. For insurance and legal purposes, seek medical evaluation even if injuries seem minor.
