Q: I left my car with a mechanic. One of his employees hit my car when he was driving his personal car. Is the mechanic/employer responsible?
A: This hinges on whether the employee was working at the time.
Was he working at the time? If so, the dealer would be responsible for the actions of the employee. If he was not working at the time, you can either deal with your insurance company, the employee’s insurance company or the employee directly.
They are not responsible just because it occurred on their property. You need to show that he was working or that the employer was benefitting from him being there at the time.
