VicRoads has rejected a Maribyrnong council request for flashing speed limit signs on Somerville Road outside Kingsville Primary School.
Parents and the council argue the decision fails to protect the safety of children crossing the busy truck route.
The council wrote to VicRoads in August, seeking electronic flashing 40km/h school zone signs on Somerville Road, Yarraville, and outside Gilmore Girls College in Barkly Street, Footscray.
The request followed a strategic risk assessment that reported a number of heavily laden trucks were failing to stop at red lights at the Kingsville Primary School crossing.
“Somerville Road has a number of speed zone changes, which can be a problem for inattentive drivers,” the report stated. “Because of [the] overall environment, LED 40km/h signs for this location are considered essential.”
But VicRoads regional director Patricia Liew said the signs would be installed only on roads with a 60km/h speed limit and carrying at least 10,000 vehicles per day.
