How frequently should air brake systems be inspected for safety?

Answer: B — Regularly or at least once a year

Air brake systems should be inspected regularly or at least once a year to ensure their safe operation. This frequency is critical because air brakes are vital to the braking performance of commercial vehicles, and any malfunction can lead to serious accidents. Regular inspections help identify potential issues, such as leaks, worn components, or air pressure problems, allowing for timely maintenance and repairs. Annual checks align with safety regulations and industry standards, providing a balance between thoroughness and practical maintenance schedules. In contrast, less frequent inspections could overlook necessary repairs, compromising safety on the road.
