What must you do with any defect or deficiency found on your passenger vehicle?

When a defect or deficiency is found on a passenger vehicle, reporting it to the carrier you work for in writing is crucial for several reasons. First, it ensures that there is an official record of the issue, outlining the specific problems that need addressing. This documentation can be important for liability, safety, and maintenance tracking.

Additionally, reporting the issue, even if it's at the end of the day, allows the carrier to take appropriate action. This may involve scheduling repairs to ensure the vehicle is safe for operation, thus promoting not only individual safety but also the safety of other road users.

While addressing defects immediately might seem urgent, it's not always feasible if you're unable to fix it yourself; thus, the next best step is to notify the carrier properly. Mentioning the issue verbally doesn’t guarantee it will be acted upon, and ignoring the problem could lead to more significant safety hazards down the line. Hence, formal written communication is the most responsible approach.
