Be on time: some services charge a penalty for late availability when they arrive for pick up.  Plan ahead, especially with clients that you don’t know well, to ensure plenty of prep time.
 

Identify you and your client: your TRC vest and badge will help identify you to the client.
 

Positive identification of your driver: make sure that the information about vehicle type and driver description are a match before entering the vehicle.
 

Who gets the door: you, as TRC Chaperone, will open and close the door for the client.
 

Where to sit: enter away from traffic, if possible.  If your client has a physical impairment, seat the client first and then, being aware of traffic, enter the vehicle by the other door. Sit next to the client. (If COVID-19 guidance or other local health department or guidance applies, consider sitting in the backseat or driving a vehicle immediately behind the client if necessary.)
 

Route: the driver will likely use GPS to find a route, but if you have concerns about the directions, say something.
 

Leave the vehicle the way you found it: check for all belongings and remove any trash as you leave.
