Carpool parking

The Transportation & Parking (T&P) Office offers carpool parking in the Clayton, Metro or Newstead Garages and on select surface lots as availability allows. T&P will issue a garage-specific access card or surface lot-specific permit at the time of registration.  After registration, the Facilities Integrated Service Center (FISC) will forward all demographic information to RideFinders to secure the RideFinder Guaranteed Ride Home benefit in case of an emergency.

The carpool program prohibits more than one vehicle at a time in/on a WUSM parking facility from utilizing a parking access card or permit.  If misrepresentation or misuse of the carpool program is found, WUSM reserves the right to revoke all parking privileges for the current year.

It is the responsibility of all carpool participants to notify the Facilities Integrated Service Center (FISC) when leaving WUSM employment,  taking a leave of absence or changing the registered riders in a carpool.

To register for carpool parking, please visit the FISC on the first floor of the Mid Campus Center, 4590 Nash Way, St. Louis, MO 63110.
