"Remember". This means whatever restriction is defined by the sign above it was already in effect and they're just reminding you. This is used often for speed limits. If you see a speed limit sign with RAPPEL below it, the speed limit is not changing at the sign because it was already in effect. |
"In rainy weather". Often used below a sign warning of a slippery road. |
"Factory exit". Simply warns you of the presence of a factory; does not imply anything about WHEN the factory operates or changes shift or anything. |
Warns of a high-voltage line 6m or lower above the road. Could also warn that the train tracks you're about to cross are electrified. |
