How do double decker busses not fall over?
How do double decker busses not fall over? By regulation British double decker busses must be stable when tilted to 28 degrees, London busses are tested to 35 degrees. The weight in the bus is low down. So the centre of gravity is low. So the centrifugal force required to tip it over is greater.
Is it safer to be on the top or bottom of a double decker bus?
Lo told the Post that the middle area of the lower deck of a bus was relatively safe for passengers in a collision. “The area is closer to the centre of gravity of the vehicle, so passengers will absorb less vibration and impact force when the vehicle collides with something,” Lo explained.

What keeps double-decker buses from tipping over?
By regulation British double decker busses must be stable when tilted to 28 degrees, London busses are tested to 35 degrees. The weight in the bus is low down. So the centre of gravity is low. So the centrifugal force required to tip it over is greater.

Is a double-decker bus more stable than a normal bus?
The benefit of double deckers is that they're easier to navigate around curves. The disadvantage is that they're somewhat less stable in turns as they have a higher center of gravity.
