If we need someone at the last minute due to a cancellation or a no-show for a shift, we will send out a group text to those on the Standby list. Once a more permanent position becomes available those on the Standby list will be first in line. Permanent volunteers are rostered once per month, though sometimes they may take on an extra shift if we are short. We are always looking for people who can drive our vehicles on their shift, however if a volunteers is not comfortable driving then that is not a problem. We have a van and a stations wagon, both vehicles are automatic. For insurance purposes drivers must be 25+, non-drivers 16+.
