Exploding car

Car explosions (of 30 tons or more) are strictly forbidden in this area of CERN.  What a relief!

Just to be safe you should also not carry a 30 ton orange peacock on the roof of your sedan; because–come on people!–a 30 ton peacock deserves better.

This is near the hump on Route Rutherford passing between the PS and ISR.

(In all seriousness, I have seen versions of this sign posted by people as far away as China.  I’m pretty certain it forbids vehicles of 30 tons or more from carrying (in)flammable loads.  The official French version is a little different, a bit more like a jeep firing a canon at you.)
