Drivers that flout the Variable Speed Limit restrictions in place along a busy stretch of the M4 around Newport will face tougher enforcement action.
The warning is being issued ahead of a new safety campaign being launched today which aims to ensure drivers are more aware of and adhere to the variable speed limits in place on the M4 between Junctions 24 (Coldra) and 28 (Tredegar Park) before enforcement action is stepped up.
The Welsh Government introduced a Variable Speed Limit along this stretch of road in 2011 to reduce congestion and improve safety and journey time reliability.
Since its launch the scheme has helped to improve traffic flow and reduce the number of collisions along this stretch, with the majority of drivers adhering to the limits in place.
However, a minority of drivers continue to flout the displayed limits and act as if the restrictions do not apply to them so it is these motorists we are primarily targeting with this awareness campaign and subsequent enforcement action.

The M4 Eastbound will close tonight at the Brynglas Tunnels in the first of a series of closures in either direction which will continue, with breaks, until February 2018.
The tunnels are being refurbished.
Traffic Wales says the M4 will be closed between junctions 25A and 26 from 8pm to 6am on up to five nights per week. The A48 Southern Distributor Road in Newport is the dedicated diversion route for all eastbound or westbound traffic.
The diversion will be in place between junctions 24 and 28 of the M4. But local traffic will be allowed to travel up to junctions 25a and 26 in order to access local routes.
Closures will usually be in place in one direction at a time but both tunnel bores may need to be closed for short periods of time for safety reasons.
