Why is it important for fuel containers on buses to be installed on the underside of the vehicle?

Installing fuel containers on the underside of vehicles, such as buses, is crucial for several safety reasons, particularly to minimize the risk of explosion in case of accidents. When fuel containers are located lower on the vehicle, they are better shielded from impact during a collision, which decreases the likelihood of punctures or breaches that could lead to leaks or fires.

Additionally, this placement helps in maintaining the center of gravity of the bus, enhancing its stability during operation and reducing the risk of rollover incidents which are pertinent to the safety of the fuel system. Furthermore, being lower to the ground means that flames or explosions resulting from a compromised fuel container are less likely to spread to the passenger compartment, thereby enhancing overall safety for passengers and drivers alike.

While other aspects, such as protecting from road debris or improving vehicle aerodynamics, are also considerations in vehicle design, the primary focus of placing fuel containers underneath is to ensure safety and mitigate risks associated with potential accidents.
