What is a crucial aspect of wiper operation during pre-trip inspections?

The operation of the wipers is a critical safety feature that ensures visibility for the driver under various weather conditions. For a Class A CDL pre-trip inspection, it is essential that wipers must work properly. This means they should effectively clear rain, snow, or any debris from the windshield, allowing the driver to maintain an unobstructed view of the road.

If the wipers are not functioning correctly, it can compromise safety by impairing visibility, leading to dangerous driving conditions. Regularly checking the wipers during pre-trip inspections ensures that they respond adequately to environmental conditions, which is vital for safe driving. Properly functioning wipers not only enhance safety but also contribute to the overall maintenance and reliability of the vehicle during its operation.
