The safety of pupils attending a school near Aberdare is being put at risk as the speed limit is "unacceptably high".
Locals in the rural village of Penderyn want to see the speed limit lowered to 20mph claiming the current 40mph speed limit "poses a significant risk to the health and safety of local residents as well as children and parents attending the school".
Parents at Ysgol Penderyn who set up an action group at the beginning of the year held a protest march on Saturday to air their frustrations and further highlight their concerns.
More than a hundred local residents, parents and children joined the march through the village.
The action group have sent numerous letters and submitted a petition to their local authority but RCT have issued a statement saying that while they understand the concerns of the campaigners they feel implementing other measures would be more appropriate.
Parents claim they feel even more frustrated as they believe Ysgol Penderyn is the only school within RCT that still has a 40mph limit surrounding it.
The Welsh Government have issued statutory guidance on speed limits which states that 30 mph should generally be the norm in rural villages, as Penderyn, with 20mph speed limits or zones where appropriate, such as 20mph speed limits or zones where appropriate and at appropriate times of the day.
