What are the grounds for revoking a driver's license in Arizona?

The correct answer highlights the significant and serious infractions that can lead to the revocation of a driver's license in Arizona. DUI offenses are treated very seriously, reflecting the state’s commitment to public safety and the dangers associated with impaired driving. Moreover, driving without insurance is another critical concern, as Arizona law mandates that all drivers carry valid insurance coverage. Accumulating too many points on a driving record is also a crucial factor; Arizona utilizes a point system where certain traffic violations carry specific point values, and reaching a certain threshold can result in license revocation.

In contrast, while failure to pay traffic fines might lead to other penalties, such as fines or collection actions, it does not directly result in revocation by itself. Driving with an expired license, although illegal, is typically addressed with fines or penalties rather than outright revocation. Frequent parking violations, while they can be problematic and indicate irresponsible behavior, do not affect the driver's license status in the same substantial manner as the infractions mentioned in the correct answer. This distinction illustrates the emphasis placed on actions that directly endanger public safety and violate major legal requirements.
