Class A CDL Pre-Trip Inspection Practice Exam

The indication of a failure in the washer system of the vehicle is when the washer does not spray properly. This situation typically manifests as insufficient fluid being sprayed onto the windshield, which can hinder visibility when driving, especially in adverse weather conditions. A properly functioning washer system is crucial for maintaining clear visibility, and any issues with the spray can directly affect the driver's ability to see the road clearly. This can ultimately compromise safety. In contrast, while having wipers that continuously move in a circle may suggest a problem with the wipers themselves, and wipers that are too slow may indicate an issue with their motor or wear, these do not specifically point to a failure of the washer system. Tinted windows do not have any relevance to the operation of the washer system and would not indicate a failure in that regard.
