What is a common risk of driving with insufficient air in the brake system?

The brakes may fail to engage
The air compressor may overheat
The vehicle may accelerate uncontrollably
The steering system may lock

The correct answer is: The brakes may fail to engage

Driving with insufficient air in the brake system significantly increases the risk of brake failure. Air brake systems rely on compressed air to operate effectively, and if the air supply is inadequate, the brakes may not function as intended. This can lead to a situation where the driver is unable to slow down or stop the vehicle, posing a serious danger not only to the driver but also to other road users. Insufficient air can also affect the stability and efficiency of the braking system, increasing stopping distances and reducing overall control of the vehicle. The other options, while they may present their own risks, do not directly stem from the problem of insufficient air in the brake system. It’s crucial for drivers using air brakes to monitor their air supply carefully to ensure safety on the road.
