Drivers in Spain are being warned to look out for a new traffic sign designed to highlight intersections monitored by automated red-light cameras. The S-991c sign, officially known as “Red Light Control”, was added to the Directorate-General for Traffic’s (DGT) catalogue in 2025 and alerts drivers that any red-light violation will be automatically detected and recorded.
The sign features a red traffic light alongside symbols representing electronic monitoring and vehicle silhouettes. It was introduced to replace the variety of local warning signs previously used by councils across Spain. Traffic officials say the standardised design will make it easier for drivers to recognise junctions where red-light cameras are in operation.
Running a red light is considered a serious traffic offence under Spanish law. Drivers caught crossing when the signal is red face a €200 fine and the loss of four points from their driving licence. The penalty applies regardless of speed, meaning drivers can still be fined even if they are driving within the legal speed limit.
The cameras are installed at traffic lights where authorities want to improve compliance and road safety. Sensors embedded in the road detect when a vehicle crosses the stop line after the light has turned red, triggering cameras that capture photographic evidence of the offence, including the vehicle registration number, date and time.
While drivers may proceed through an amber light if stopping safely is impossible, there is no such exception once the light turns red. Traffic authorities say the new sign serves as a clear warning that the junction is under constant surveillance and that any infringement will be automatically recorded and processed.
