Possibly, but not necessarily.
If the heart attack, stroke, seizure, or other health condition was sudden and unforeseeable, the driver may not have been able to prevent what occurred and may not be negligent for the crash.
However, the driver could be considered negligent in a head-on crash if:
- The medical emergency was associated with an existing health condition and the driver avoided medical treatment
- The driver failed to take their medication
- The driver ignored any major symptoms or warning signs of their condition
