Mary Johson is traveling on I-270 in her own vehicle in the center lane of traffic. Bob Wilson is driving his company truck owned by his employer, Anderson's Medical Supply. Andersons is solely based in Columbus, Ohio and provides medical supplies to local nursing homes and assisted living centers which operate here in Franklin County.

Wilson is traveling in the left-hand lane of traffic. As he talks on his phone to a customer, he changes lanes without looking. Johnson, who is in Wilson's blind spot, does see the truck enter her lane. Wilson side swipes Johnson causing her to lose control and crash into a retaining wall. She suffers a broken left hip and is off work for approximately 6 months. Her lost wages amounts to $50,000. Her medical bills are $500,000.
