In Culemborg two delivery vans stop to unload boxes. Van 1 is next to sign E1 (blue with a red border and one red diagonal stripe). Van 2 is next to sign E2 (blue with a red border and a red cross). Who may stay standing there like that?
Van 1 and van 2 may both stop here briefly to unload
Van 2 may briefly unload here, van 1 may not stop here
Van 1 may unload here, van 2 may not stop here
Explanation
False — You swap the two signs. One diagonal stripe (E1) is a parking ban: stopping briefly to load or unload is allowed. A cross (E2) means you may not stop there, so no unloading either (Book p.160).
