Which of the following is NOT a major violation for JOL holders?

A parking violation is considered a relatively minor offense compared to the other options listed. Major violations for Junior Operator License (JOL) holders in Massachusetts typically include serious offenses that have substantial consequences, such as leaving the scene of an accident, reckless driving, and driving under the influence (DUI), all of which can lead to significant penalties including license suspension, fines, and potentially even criminal charges.

On the other hand, while parking violations can result in fines and citations, they do not carry the same severe repercussions in terms of points on a driving record or impact on a JOL holder's driving privileges. Therefore, identifying a parking violation as not being a major violation aligns with the emphasis on serious traffic offenses relevant to maintaining safety on the road.
