You indicated that an event or exposure occurring in the work environment caused or contributed to the resulting injury or illness, or "significantly aggravated" a pre-existing injury or illness.
The work environment includes "locations where one or more employees are working or are present as a condition of their employment" (29 CFR 1904.5(b)(1)). This includes wherever a worker is driving or riding in the interest of the employer. It does NOT include commuting between work and home or a temporary residence, like a hotel during a trip.
Was the affected employee’s injury or illness the result of a motor vehicle accident?
