The DMV’s Investigations Division is staffed by licensed peace officers who have the authority to conduct surveillance, collect evidence, interview witnesses, and enforce the California Vehicle Code.

-
Law Enforcement: Police reports or arrests may prompt a DMV review

Routine Audits: Especially for driving schools, dealerships, or CDL holders
Once a concern is flagged, a DMV investigator will begin a fact-finding process to determine whether there’s enough evidence to take action.
What Happens During the Investigation?
The investigation process generally includes:
1. Initial Review
The investigator reviews records, complaints, or reports to assess credibility.
2. Surveillance and Field Work
In more serious cases, DMV investigators may visit your home, workplace, or other relevant locations. They may also take photographs or collect other physical evidence.
3. Interviews
You may be contacted for an interview or asked to respond to specific questions. Investigators may also interview witnesses, such as employers, medical professionals, or accident victims.

-
Medical records (with proper authorization)

Driving records and past violations

Employment documents
