Following several at-fault crashes and a family member's written concern about a driver's health, the DMV asks the driver to complete a knowledge and drive re-examination. Why does this authority exist?

Why C is correct

Licensing is the state's mechanism for confirming, at intervals, that a driver remains competent and medically fit for the task — and some conditions of concern surface between renewals. The re-examination power lets the agency verify fitness on evidence: crash patterns, physician reports, family or police referrals. It exists because the road is a shared environment and the licence is the state's only lever for ensuring the person holding it can still operate within it. Re-examination is individualised: it responds to a specific driver's evidence, not to an age, a diagnosis or a number of crashes alone.

Why the other options are wrong

A. To raise additional licence fees from drivers with poor records

Fee collection is ancillary to every licensing function, and re-examination in particular costs the agency far more than the fee recovers. The purpose is fitness assessment, not revenue.

B. To punish drivers for having crashes, which are always the driver's fault

Crashes are not treated as moral failures, and re-examination is not a punishment. It is a fitness check triggered by evidence, which is why it can end in no change at all, in restrictions, or in further training.

D. Because insurance companies require the state to re-test their customers

Insurers are private parties with their own underwriting tools and no authority over state testing. The re-examination power runs from the state's duty to the road's users, not from an insurance requirement.

On the road

A retired teacher's family notices right-turn confusion after a minor stroke and files the referral form themselves. The re-examination finds her driving sound with a restriction — daytime driving only — that she accepts with relief. The power exists for exactly this: a specific driver, specific evidence, and a licence adjusted to fit the evidence rather than the family's worry or her pride.
