A vehicle ahead of the fire truck swerved to avoid a ladder and the truck swerved too, striking the guardrail on the right shoulder and overturning multiple times, according to the California Highway Patrol.
Eight firefighters were injured in the incident, six of them critically.
Nichols and his wife have a 6-month-old son named Theodore. The GoFundMe will help cover child care costs during his recovery.
