What is the test for a motor vehicle license holder to sue the Department of Motor Vehicles?

The safety of the public thoroughfares is, without question, an "important" state interest. " ' "The use of the public highways by motor vehicles, with its constant dangers, renders the reasonableness and necessity of regulation apparent.... Any appropriate means adopted by the states to insure competence and care on the part of its licensees and to protect others using the highway is consonant with due process." ' " (Hernandez v. Department of Motor Vehicles, supra, 30 Cal.3d at p. 79, 117 Cal.Rptr. 566, 634 P.2d 917, original emphasis.)
