Georgia Commercial Driver License Practice Test

What should you do if you experience a severe drop in air pressure during driving?

1. Keep driving as the vehicle is safe

2. Stop for a break immediately

3. Shift into a lower gear

4. Stop the vehicle as safely and quickly as possible

The correct answer is: Stop the vehicle as safely and quickly as possible

When experiencing a severe drop in air pressure while driving, the appropriate action is to stop the vehicle as safely and quickly as possible. This is crucial because a significant drop in air pressure can indicate a malfunction in the air braking system, which is essential for the safe operation of commercial vehicles. If the air pressure drops too low, the brakes may fail to function properly, putting both the driver and others on the road at serious risk. Taking immediate action to stop the vehicle helps prevent potential accidents and allows for a thorough inspection of the braking system before continuing operation. It is vital for any commercial driver to be attentive to changes in vehicle performance and respond swiftly to issues that could compromise safety. Other options may seem appealing but do not address the urgency of the situation. Continuing to drive could lead to brake failure, while taking a break does not resolve the underlying issue, and shifting into a lower gear is not a relevant or effective response to a drop in braking air pressure.
