Road safety signs have been erected outside Goldthorpe Primary and Carrfield Primary, Bolton-upon-Dearne.
Dearne MP John Healey launched the initiative last year alongside local councillors and he now wants to see similar speed signs put up for other schools, and extra steps taken to make the roads safer for schoolchildren.
Barnsley Council agreed to put up 20mph signs as part of a pilot scheme, which highways bosses have now agreed to extend with a road safety review of all primary schools across the borough.
John said: “It’s good to see the signs have finally been installed and I’ve been told they are already having a positive effect on traffic in the area.
“I’ve spoken with parents and students and I know how busy the roads outside these schools can get at drop-off and pick-up times.
“This is a real win for all those involved in our campaign and it wouldn’t have happened without such strong community support.
“Now I would like to see this pilot scheme extended to other schools.”
