The council's decision to ban turning into and out of a busy Ealing road has sparked a row, with some motorists claiming signs are not clear enough.
Following a "number of accidents" the council claim the road safety trial will ease congestion and make it safer for pedestrians and cyclists.
But the ban, which has also been praised by some drivers, has drawn criticism from some motorists who have raised concerns of unclear signage, congestion and three point turns.
Jagdeep Gill, a van driver who has been driving through Longfield Avenue for more than 20 years, unknowingly broke the ban when he turned right into Longfield Avenue this week because he claims the sign is not clear enough.
The 58-year-old, who only realised there was a ban when a resident told him, added: "It is just a rip off; a lot of people are going to get done.
"I didn't see the sign, for more than 20 years I have been going the same route. There is no road marking, we (drivers) don't expect it after 20 years."
Warning signs in double figures
Conservative Cllr Seema Kumar said she stood by the road earlier this week and saw 30 cars breaking the ban within just 20 minutes.
The Ealing Broadway representative said she also saw motorists doing three point turns, because of the ban, that she believes are dangerous.
She added that drivers in the area have been complaining to her about congestion in neighbouring roads, a view shared by Conservative Cllr Alex Stafford, who also represents Ealing Broadway, but refuted by Cllr Mahfouz.
But Labour Cllr Bassam Mahfouz said there are a total of 14 clear signs warning motorists of the ban and added road markings are not legally possible.
Cllr Mahfouz said: "Two people were hit at the junction so the reason we have done it is for road safety purposes.
"There are no less than 14 signs as you approach the junction, if you're telling me that that he (Mr Gill) has not seen signs I would be very worried about the driver."
And Facebook user Carol Hunter Thomson posted on the social networking site: "Pedestrians are the problem, they make things more difficult for drivers to get around.
"Not surprised there have been accidents. Well done Ealing Council, a great way to keep the traffic flowing in Ealing Broadway."
Motorists will be sent a warning for their first offence if they break the ban for "a few weeks", according to Cllr Mahfouz, before issuing financial penalties.
