The site surveillance service managed by Didier Constant and Hubert Montané (SCE-DOD) is responsible, among other things, for supervising compliance with the parking regulations on the CERN site. As vehicles may not be left on a CERN car park for longer than 5 consecutive working days,  except in designated long-stay car parks, the guards from Access Control Service (access.surveillance@cern.ch) carry out regular inspection rounds.

CERN users are entitled to leave their vehicles parked at CERN for a longer period in the car park subject to completing the Request for a long term parking permit / autorisation pour un stationnement de longue durée prior to their departure.
