Scheduling a Ride
Once you have been notified that you are eligible to use Tri Delta Transit’s senior paratransit transportation, call 1-925-754-3060 to schedule a ride. Senior paratransit trips can be booked by phone from 6:00 a.m. – 6:00 p.m. daily, including holidays.
Ride requests may be made one to three days in advance. When requesting a ride, please give the reservationist the following information:
- Your name and pick-up address
- The date and time of the appointment or your preferred pick-up time*
- The destination address and phone number
- The preferred return time*
- The return address
- If you will be using a cane, walker, service animal or mobility device
*Remember this is shared ride transportation. To accommodate as many ride requests as possible, a senior paratransit confirmed pick-up time may be up to one hour before or after the requested pick-up time.
Please also note: If your arrival time is important (e.g., doctor appointment), please give the reservationist your appointment time. If your arrival time is not an appointment time (e.g., shopping), please give the reservationist the time you prefer to be picked up from your starting location.
The day before your scheduled ride, an automated call, with a confirmed pick-up time, will be made to the preferred number you indicated on your senior paratransit application.
If the message is not clear or is incomplete, please contact the Tri Delta Transit scheduling line at 1-925-754-3060 to confirm your pick-up time.
