Motorists driving on or near trunk roads will soon be forced to keep their speed to 20mph during peak periods around eight schools, the Welsh Government has announced.
The speed signs are expected to become law in 2015, after advisory limits are created next April - on the condition that legal orders are approved.
Failure to comply with the restrictions could land drivers with fines and penalty points.
If the project proves effective and the money is available, the Welsh Assembly will extend the scheme to other schools in the vicinity of trunk roads by the end of 2016/17.
Further measures are expected to be published early next year.
Edwina Hart, the assembly's Transport Minister who announced the £500,000 plan, said she is determined to improve the safety set-up for people who live on or next to trunk roads.
The Welsh Assembly's community safety review of the country's trunk roads highlighted the schools which are set for selection.
