What are the circumstances under which a Commercial Junior Operator can lose their license?

A Commercial Junior Operator can lose their license primarily due to serious violations such as Driving Under the Influence (DUI) or accumulating a significant number of points on their driving record. These types of violations indicate a higher risk to public safety and reflect poor driving behavior, which can lead to the suspension or revocation of a commercial license.

In contrast, minor traffic violations generally do not carry the same level of consequence and may not lead to losing one’s license, especially if they do not result in a substantial points penalty. Losing a vehicle’s registration may affect the ability to operate that specific vehicle legally but does not directly result in losing the operator's license. Likewise, failing to renew the license in time may lead to fines or penalties but does not automatically equate to losing the license, as it can often be renewed with proper action. Therefore, the severity of the violations associated with option B makes it the correct answer regarding circumstances that can lead to a loss of the Commercial Junior Operator license.
