Park Ward's new Labour Councillor Steve Kermode has been working with police to clamp down on dangerous drivers in Lydiate.
Cllr Kermode, who was only elected to Sefton Council earlier this month, has been working with police to tackle speeding motorists on Moss Lane.
The issue was raised by residents who told Cllr Kermode that because of the cars exceeding the speed limit, the road was an accident waiting to happen.
Cllr Kermode said: "Residents raised their concerns about speeding cars on Moss Lane with me and I immediately took it up with the police.
"Merseyside Police conducted a survey and found that there was a large number of speeding cars on the road.
"They have since increased speed patrols in the area.
"We will continue to monitor this situation and reassess the problem over future weeks and months."
Sandra Williams, who lives nearby, praised Cllr Kermode for taking swift action after hearing residents' concerns.
Sandra said: "People here have been complaining about speeding on Moss Lane for some years, but our concerns have gone unheard.
"But within weeks of getting in, Cllr Kermode has taken action.
"From personal experience living just off this road, I think the police will discover that there is a problem and action is needed."
Cllr Kermode urged people to reduce their speed on roads throughout Lydiate and Maghull.
Cllr Kermode said: "Moss Lane is very close to a number of schools in Lydiate. There is a play area on the road which means there are young people who will be out and about.
"Speeding cars are a danger which our children should not have to contend with.
"We all know the statistics about speed increasing the likelihood of death or serious injury in the case of an accident.
"I urge all motorists to slow down, particularly in more residential areas. Not only will you reduce the risk of causing an accident, you will also eliminate the risk of being handed a fine by the police."
