How Medical Conditions Affect Your California Driving Privileges

Certain medical conditions can lead to DMV action against your license. Whether it is a seizure disorder, diabetes, vision problems, or cognitive decline, the DMV has specific protocols. Understanding these rules helps you prepare and protect your right to drive.

Conditions That Trigger DMV Review

The California DMV may review your driving privileges if you have certain medical conditions that could affect your ability to drive safely. Common triggering conditions include seizure disorders or epilepsy, diabetes with episodes of hypoglycemia or loss of consciousness, dementia or Alzheimer's disease, macular degeneration or other vision impairments, Parkinson's disease, stroke with residual effects, and narcolepsy or sleep disorders causing excessive daytime sleepiness.

California law requires physicians to report patients they believe have conditions involving lapses of consciousness under Health and Safety Code Section 103900. However, the physician report does not automatically result in suspension — it triggers a re-examination process where you can present countervailing evidence of your fitness to drive.
