Agency caregiver without car.

What is too much TV? Since watching TV expands our world, introduces us to people we can’t meet in person, and provides us with topics to think and talk about, it can be more stimulating than riding in a car to a place we’ve been a hundred times before.

Not to mention that we’re unlikely to be victim of a car crash while sitting at home watching TV.

Was driving "Miss Daisy" around part of what was expected when you contracted with the agency?
Are the Caregivers Insured to transport clients?
Who is going to pay the mileage?
Is mom easy to get into the car?
Get out of the car?
Is she a fall risk?
Is she apt to wander off while in the store?
All someone has to do is turn their head to look at something else and your mom could wander off. (Trust me, my Husband "escaped" from the house while I went to put some things in the drier, police found him a mile away)
There are plenty of things that can be done with no car.
Go for a walk if it is safe to do so.
Fold laundry
Play games
Plant some flowers or veggie plants.

You speak to the agency. When my brother was thinking of having an agency (was considering not going into ALF so was contemplating home help) the agency explained that indeed they DID have people who would drive, but that had to "be arranged". He would have wanted transit to appointment, to shop and etc. But in order for agency personnel to drive a client they must be checked for liscensure and etc.

Speak to the agency.

Given that this is just a fill in position I can't see anything wrong with having an occasional quiet day spent at home. I find it interesting that any of your agency caregivers are using their own cars to transport their clients, in my part of the world that would be a big insurance no no.
