To ensure stability, a double decker must withstand a tilt of up to 28 degrees from the horizontal plane on either side without flipping over, according to road traffic construction and vehicle maintenance regulations.

Can double-decker buses topple over? Amazingly enough they are actually very difficult to “topple over” this was a test back in the 30's proving their stability; they even put sandbags in the upper floor to simulate passengers!
How far can a double decker bus lean before it falls over? Double Decker buses are tilt-tested and must withstand an 28 degree lean from center without flipping,the above bus obviously passed!
Yes they are, however the current fleet of double deckers can only travel at a maximum speed of 50mph due to their design for mainly city work. Our Routemaster travels at around 40mph. On single carriageway roads though, the maximum speed for all buses and coaches is 50mph by law.
Due to the high operating cost, cumbersome transportation and high fuel consumption, the BEST administration stopped inducting double-decker buses after 2008. The move to decommission these buses is in accordance with government policy as the vehicles have reached their legal life of 15 years.
Not only can passengers fall off after the vehicle collides into something, but they can get hit from the ensuing debris. Five years ago, a tour bus crashed into a traffic light pole and injured 14 people in the process. There are plenty of more ways passengers can receive injuries here compared to a regular bus.
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.
The upper deck of bus,in comparison to lower, is high. Due to this fact the torque produced in upper deck is larger than the lower one. One standing in upper deck frequently experiences great push and pulls during acceleration and breaking.
Reading Buses' Bus Hound was recorded doing a lap speed of 76.785mph (123.57km/h) at Bedford's Millbrook Proving Ground. It runs on biomethane compressed natural gas and is painted black and white like a Friesian cow. It normally carries passengers around Reading. The UK Timing Association confirmed the new record.
The AEC Routemaster is a front-engined double-decker bus that was designed by London Transport and built by the Associated Equipment Company (AEC) and Park Royal Vehicles.
A double-decker bus or double-deck bus is a bus that has two storeys or decks. They are used for mass transport in the United Kingdom, the United States, Canada, New Zealand, Europe, Asia and also in cities such as Sydney; the best-known example is the red London bus, namely the AEC Routemaster.
TfL, however, estimates that a standard hybrid diesel-electric double-deck bus is in the region of £300,000. The latest New Routemaster with Euro VI engine costs £349,500.
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.
