A Sign of the Times

There has been much chatter recently on the cut about the difficulty of understanding some of the signs C&RT have and also how poorly kept the hedges are.
We try very hard to comply with the regulations as designated but we have had a  few problems recently.

What does this sign mean at the bottom of Foxton locks?

Is it for the water point?

Or waiting to ascend the Foxton staircase?

Or 24hrs waiting for any reason?

A t Norton  Jct we were ready to comply if only we knew what they wanted us to do or not do.
