What is the definition of a 'prior conviction' under implied consent?

• A. A conviction within the last five years
• B. A conviction for any offense in the driver's lifetime
• C. A conviction that has no limit
• D. A conviction for a violation within the fifteen-year period prior to the current offense

Answer: (D)

In implied consent, a prior conviction is a conviction for an implied-consent violation that occurred within a specific look-back window before the current offense. The window most commonly used in practice and exams is fifteen years. So if you were convicted of an implied-consent violation within the past fifteen years, that counts as a prior conviction for the current case and can affect penalties or license actions.

The other options don’t fit because they either use too short a window (five years), imply the look-back is unlimited (lifetime or no limit), or suggest there is no look-back at all. The fifteen-year window provides a clear, defined period to distinguish first offenses from repeat offenses for enforcement purposes.
