Which of the following is classified as a major violation for JOL holders?

A DUI (Driving Under the Influence) is classified as a major violation for JOL (Junior Operator License) holders because it poses a significant risk to public safety. DUI offenses involve operating a vehicle while impaired by alcohol or drugs, which can lead to serious accidents and injuries. For JOL holders, the consequences of such a violation are severe, often resulting in license suspension, mandatory education programs, and additional penalties that can impact future driving privileges.

In contrast, other violations such as failure to yield, expired registration, and unbuckled seatbelt typically fall under less severe categories. While they are certainly important and can lead to fines or points on the driving record, they do not carry the same level of consequence that a DUI does. A DUI represents a fundamental disregard for the law and public safety, hence its classification as a major violation.
