Final answer:
A driver's license may be canceled for failure to attend or pass a re-examination, or possession of an altered license. Minor traffic violations usually do not lead to cancellation unless they are serious or repeated offenses.
Step-by-step explanation:
A driver's license can be canceled under certain circumstances. These typically involve direct violations of legal or administrative driving regulations. Here are the circumstances relevant to the options provided:
- Failure to attend a re-examination: If a driver is required to undergo re-examination for their driving abilities and fails to attend, their license may be canceled.
- Possession of an altered license: Holding a license that has been tampered with or altered is a serious offense and can lead to cancellation.
- Failure to satisfactorily complete a driver re-examination: Should a driver not pass a mandated re-examination, their driving privileges could be revoked.
- Involvement in a minor traffic violation is generally not grounds for cancellation, but repeated offenses or serious violations can lead to stronger actions such as suspension or cancellation.
Therefore, options (a), (b), and (c) are circumstances where a driver's license might be canceled, while a minor traffic violation (d) typically does not result in cancellation.
