What should be verified about the fuel cap during a pre-trip inspection?

During a pre-trip inspection, the fuel cap is a critical component to examine. It should be verified that the fuel cap is in place with a good seal and that there are no leaks. A secure cap helps prevent fuel evaporation, which can not only waste fuel but also lead to environmental hazards. Additionally, a proper seal ensures that contaminants do not enter the fuel system, maintaining the integrity of the engine performance. Any leaks could cause fuel to spill or evaporate, which poses safety risks and potential compliance issues with environmental regulations.

Inspecting the fuel cap for a good seal and the absence of leaks is essential for the safe operation of the vehicle and helps ensure that the vehicle meets safety and efficiency standards on the road.
