I passed the roadsign below while driving home late last night, and realised that despite how many times I had seen it, I was still surprised by the choice of words used and unsure if it was actually grammatically correct.
After all, the wording on roadsigns is crucial. As we all know, it needs to be clear and succinct.
So, to my mind the words
Road liable to flooding
should be
Road liable to flood
or it could be rewritten
Road prone to flooding
Am I right, or is the original ok?
