What type of tax do car owners face according to Article IX, Section 11?

The correct answer is a license tax because Article IX, Section 11 of the Arizona Constitution specifically addresses the taxation of vehicles through the imposition of a license tax. This type of tax is levied on the privilege of using a vehicle on public roads and is commonly associated with vehicle registration and licensing requirements. The purpose of the license tax is to provide revenue for the maintenance and development of road infrastructure and related public services.

By contrast, property tax is generally assessed on real estate, income tax relates to earnings, and sales tax applies to the sale of goods and services. These other types of taxes do not specifically address the cost associated with owning and operating a vehicle in the same manner as a license tax, which is directly linked to vehicle registration and regulation.
