As a kid, I wondered why my parents would continue driving past those without even flinching.
“Bridge Ices Before Road”
I originally took this “before” spatially, as like “in front of”. So the bridge ices in a very particular spot — just before the bridge ends and your route becomes road again.
Reminds me of me as a kid getting upset with my grandmother once for taking a sip from her water bottle while driving, because I had heard from so many tv ads that "drinking while driving" was highly illegal.
and this is why symbolic signs are preferable to text, if native speakers of the language can't reliably interpret them correctly it's a bit of a problem!
