The Arizona Department of Transportation (ADOT) is a multimodal transportation agency serving one of the fastest-growing areas of the country. ADOT is responsible for planning, building and operating a complex highway system in addition to building and maintaining bridges and the Grand Canyon Airport. A major component of the organization is the Motor Vehicle Division, which provides title, registration and driver-license services to the general public throughout the state of Arizona. ADOT is funded by the people who purchase fuel, drive or own private and commercial vehicles, or use transportation services. To build and operate the state’s transportation systems, individuals and businesses invest money through fuel taxes, motor-carrier fees and vehicle title, registration and license fees. About 80 percent of the money ADOT collects returns to the private sector in the form of paychecks and payment for transportation services and materials.
