What Is a DMV Medical Reevaluation?

California law requires the DMV to investigate any report suggesting that a licensed driver may no longer be medically or physically fit to drive safely. When such a report is received, the DMV can require the driver to undergo a reevaluation, which may include written tests, a behind-the-wheel driving test, a vision test, and a formal hearing before a DMV Driver Safety hearing officer.

The DMV receives these reports from multiple sources. Most people are surprised to learn just how many ways this process can be triggered.

Here's how the DMV typically learns about a potential medical concern:

One detail many people don't realize: a family member filing a DS-699 form is one of the most common triggers. It often comes from a place of genuine concern — but the driver receiving the letter may feel blindsided, even betrayed. That emotional context is real, and an attorney who understands it can help you navigate both the legal process and the family dynamics with clarity.

What Conditions Can Trigger a Reevaluation?

California law specifically lists conditions that physicians are required to report to the DMV. These include:

Seizure disorders and epilepsy are among the most common. A single seizure can trigger an immediate license suspension until the driver demonstrates a seizure-free period — typically three to six months, depending on the circumstances — and passes a reevaluation.

Dementia and Alzheimer's disease frequently come to the DMV's attention through physician reports or family members. These cases require careful handling because the driver's own perception of their abilities may not match the clinical picture — and an attorney can help ensure the process is fair and that the driver's dignity is respected throughout.

Diabetes and hypoglycemia are reported when a physician believes uncontrolled blood sugar creates a risk of loss of consciousness behind the wheel. Many diabetic drivers are entirely capable of driving safely with proper management — but they need to demonstrate that to the DMV effectively.

Vision impairments, including conditions like macular degeneration or glaucoma, may trigger a reevaluation when a physician believes acuity or field of vision has declined to an unsafe level.

Cardiac conditions, including recent heart attacks, arrhythmias, and syncope episodes, are reportable when a physician believes the risk of sudden incapacitation is significant.

Neurological conditions such as Parkinson's disease, stroke, and traumatic brain injury can all trigger reviews. These cases often involve nuanced medical evidence about current functional capacity versus what the diagnosis alone implies.

Sleep disorders, particularly severe obstructive sleep apnea with documented compliance issues, may be reported if a physician believes the driver poses a risk of falling asleep at the wheel.

Substance use disorders, when documented in medical records, can come to the DMV's attention in various ways and may trigger a reevaluation alongside or separate from any criminal proceedings.

What the Reevaluation Process Actually Looks Like

The DMV's medical reevaluation process is not a single event — it unfolds in stages, and each stage is an opportunity to either resolve the matter or contest an adverse decision.
