How much to charge a client for driving them to doctors appointments?

OH can of worms!! If your vehicle insurance company finds out, they will drop you like a hot potato.

Mchristine, do you work as an "independent contractor" or through an Agency?

My Dad had caregivers through an Agency and the Agency would charge so much per mile if the caregiver did the driving in their own car. If the caregiver used the client's car, there was no charge.
