Final answer:
The second conviction for a prior offense leads to mandatory driver license revocation. The revocation period depends on the specific jurisdiction and may be influenced by the time frame of the prior offense.
Step-by-step explanation:
The second conviction for a prior offense that occurred before the current offense leads to mandatory driver license revocation. The revocation period will depend on the specific jurisdiction, as each state or country may have different laws and regulations.
For example, in some states, the revocation period may be longer if the prior offense happened within a certain time frame of the current offense. Let's say that the revocation period is 1 year. If an individual had a prior offense within the last 5 years and is now convicted of another offense, their driver's license will be revoked for 1 year based on the prior offense.
