he 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.
From the early 20th century, trucks were the primary mode for hauling copper from Arizona mines to processing and manufacturing plants, raw cotton to gins and mills, cattle to railheads and local markets, and citrus to packing and distribution centers. Today’s modern trucking industry operates in every aspect of economic life, delivering textbooks, medical supplies, retail goods and the building blocks of highways and energy production for the state’s growing population.
