New speed cameras in Portugal from September 1st

From September 1st, 37 new speed cameras from the National Speed Control System (SINCRO) will come into operation in phases. Of these 37, 12 will be average speed cameras. 

To accompany the announcement of the new radars, the National Road Safety Authority (ANSR) launched the "Radars save lives" road safety campaign. The aim of the campaign is to present the locations where the new radars are placed, so that people know the areas and comply with the speed limits, protecting the lives of drivers and pedestrians.

How do average speed cameras work?

These cameras measure the average speed of a vehicle between two points, and not the instantaneous speed of a vehicle at a specific location, like the usual cameras.

For example, on a particular stretch of road, a vehicle is first checked by an average speed camera. Further along, another average speed camera checks the same vehicle a second time, and calculates how long it took the vehicle to travel the route. If the vehicle has traveled that distance too fast, taking into account the maximum speed allowed for that stretch, it will be recorded on the camera as speeding.

The average speed cameras will be in operation on highways, main routes (IPs) and national roads.

In total, there will be 123 speed checkpoints. On the Radares à Vista website you can see the speed checkpoints that are currently in operation and those that will be in operation from September 1st.
