DMV Investigations Division
"The DMV Investigations Division protects the programs and interests of the department and public through active fraud/counterfeit detection, investigation, audit and enforcement services. The Investigations Division diligently enforces laws, rules, and regulations that apply to new and used vehicle dealers, brokers, dismantlers, registrations services, vehicle verifiers, misuse of Disabled Person Parking Placard/Plates, driving schools or traffic violator schools, and other vehicle-related businesses."
Disabled Person Parking Placard/Plate fraud is HUGE here in California. There's also an internal issue the DMV is trying to deal with. Earlier this year, DMV investigators caught multiple DMV employees at offices around San Diego County selling driver licenses to undocumented immigrants.
Also, if you look carefully the next time you go to the DMV you will notice a small HT sitting on one of the desks. This is so the employees can request immediate CHP assistance for anything from someone talking on their cellphone to someone attempting to register a stolen vehicle. I once heard the Newhall DMV request CHP for someone who had shown up at their behind the wheel exam appointment completely wasted.
