CONFUSING road signs and poor consultation over a cycling festival on Sunday could produce motoring misery for the borough's car owners, says a residents' group.
Members have blasted the Greater London Authority (GLA) and Ealing Council in the run-up to the Mayor of London's 7.5-mile Sky Ride around the borough.
They say motorists are bound to park in roads meant to be traffic-free for the festival because signs are so confusing. Anthony Elley of West Ealing Neighbours, said: "Many people don't understand and I'm going round warning them.
"The signs are too complicated and when they say no parking on the north or south side (of the road), many people won't know which is north and which is south. Drivers will be fined through no fault of their own and their cars towed away."
He also attacked the lack of consultation and information about which roads were on the cyclists' route, because buses would also be subject to disruption.
The GLA is responsible for traffic management and signs.
An Ealing Council spokeswoman said: "We are working closely with the GLA to minimise disruption and make it a real success.
"Parking suspension signs have been placed in all the affected roads to make it clear where people can and cannot park. The GLA is ensuring its contractors will work with motorists as much as possible and they will be taking a common sense approach.
"Residents with concerns are being asked to approach a steward."
Thousands of visitors are expected to take advantage of traffic-free roads and see many local landmarks on Sunday's Sky Ride. The ride starts at Lammas Park at 10am and cycling professionals Peter Kennaugh, Kjell Carlstrom, Ben Swift and Ian Stannard are expected to take part.
The route runs past Pitzhanger Manor House, Ealing Town Hall, Ealing Common and Hanwell Clock Tower, ending in Lammas Park.
