What is a common consequence of neglecting to check air brake functionality?

Answer: C — The vehicle may experience brake failure, leading to accidents

Neglecting to check air brake functionality can lead to brake failure, which is a serious safety concern. Air brakes are critical components in heavy vehicles, and proper functionality is essential for safe operation. When air brakes are not adequately maintained or inspected, they may not respond effectively when the driver applies them. This malfunction can result in an inability to stop or slow the vehicle as needed, significantly increasing the risk of accidents. In heavy vehicles, where stopping distances are longer, the consequences of brake failure can be catastrophic, not only endangering the driver and passengers but also other road users. Regular checks and maintenance are vital to ensure that air brakes are in proper working order to prevent such dangerous situations.
