Georgia Commercial Driver License Practice Test

During vehicle inspections, how often should the air supply be checked?

1. After every trip

2. Once a month

3. Daily

4. Before starting the engine

The correct answer is: Daily

Checking the air supply daily as part of vehicle inspections is crucial for the safe operation of commercial vehicles. The air braking system relies on a sufficient supply of compressed air to function effectively. Ensuring that the air supply is at the required pressure helps prevent brake failure, which can lead to accidents and endanger both the driver and others on the road. Daily checks allow drivers to identify potential issues early, such as leaks or inadequate pressure, before they can compromise safety during trips. While conducting inspections after every trip, or monthly checks may sound reasonable, those frequencies do not provide the same level of immediate assurance regarding the air supply that daily checks do. Checking before starting the engine is important, but a daily check encompasses a more comprehensive inspection, including ensuring all components related to the air supply are in good condition.
