How do double decker buses not fall over?
How do double decker buses 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 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.

How stable are double-decker buses?

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.
Why does England use double decker buses?
The main reason for their continued popularity was because the single-level buses simply couldn't hold enough people, and the longer accordion version couldn't handle London's narrow streets. People also liked the viewing capacity and having open tops.

Is top or bottom of bus safer?
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 is the safest bus in the world?
