Since the beginning of June, you may have spotted new road signs at strategic points around the CERN site. These signs indicate where reverse parking is compulsory.
This measure is intended to reduce the risk of accidents and keep traffic flowing safely. Reversing out of a parking space can be dangerous, especially when it’s onto a busy road or into a cycle path.
In the event of a site evacuation, vehicles must exit the site rapidly. Reverse parking is therefore strongly recommended wherever possible for safety reasons.
