The council added that Mr Lee’s appeal was the first in which an adjudicator found it against the authority on signage grounds.
“We will continue to review feedback, including comments on signage, to ensure the scheme operates effectively,” a council spokesperson said.
Mr Lee, 56, said: “There’s no way in the world anyone could remember all the locations of all the school zones, so people are reliant upon the signage, and it is not good enough.
“There’s two signs warning about the zone, one right as it starts and another 200 yards [182m] up the street at a busy junction.”
