More than 3,600 speed cameras are reported across Spain, including fixed and mobile cameras as well as average-speed systems, although totals vary information from which devices are counted. The Dirección General de Tráfico (DGT), Spain’s national traffic authority, maintains a separate inventory of more than 2,400 confirmed control points. A systematic review indexed by ScienceDirect examined 94 studies from multiple countries and found that speed cameras were associated with lower speeds and fewer drivers exceeding posted limits.
The headline figure of 7.57 km/h comes from the subset of 13 studies that measured changes in average vehicle speed; it is not an average result across all 94 studies. The review reported a statistically impressive reduction. Its findings concern automated enforcement across several countries, so the 7.57 km/h estimate is evidence of a general camera effect rather than a Spain-specific causal measurement. Lower average speeds and fewer speeding violations are related to improved compliance, but they remain distinct outcomes.
In Spain, enforcement includes fixed cameras that measure speed at a particular point and section-control systems that calculate a vehicle’s average speed over a monitored stretch. The latter record a vehicle’s passage at the route’s entry and exit, using its number plate and elapsed travel time. By measuring speed across a distance, section control makes it harder to slow only at a camera and accelerate immediately afterward.
Which Cameras Work Best?
Drivers who brake sharply near a visible camera and speed up after passing it are often said to create a “kangaroo effect.” A single fixed camera measures speed at one location; consecutive cameras or section control can encourage compliance over a longer road segment. The review highlights average-speed enforcement as an approach to addressing the brake-and-accelerate pattern, although the effects of different camera types depend on the locations and outcomes being assessed.
Visibility is also part of the enforcement debate. DGT Director General Pere Navarro has defended signposted cameras as a deterrent, saying: “A signposted camera deters; a hidden one only collects revenue.” The distinction is between influencing driver behaviour and the perception that enforcement is primarily punitive. In 2022, Spain recorded 3,704,675 speeding citations, a measure of enforcement activity that does not, by itself, establish changes in crashes, injuries or deaths.
Spain is expanding both point-based and average-speed monitoring. In 2026, the DGT added 33 devices, including 20 fixed cameras and 13 section-control systems, in 11 autonomous communities. The installations formed part of a plan for 122 new control points; 106 were already operating when the additions were announced. Roads named in the rollout included Madrid’s M-501, Ávila’s N-403 and Málaga’s A-355.
Where Cameras Have the Biggest Impact
The review reports speed reductions on interurban roads and positive results in locations such as school zones and roadworks. It also describes differences in compliance among road users and the role of factors including signage and sustained enforcement. The effects should be understood in context: camera placement, road conditions and the way results are measured all influence what a study records.
Spanish penalties for speeding range from €100 to €600 and can include the loss of two to six driving-licence points, depending on the seriousness of the offence. Measurement corrections are not universal: the applicable allowance can differ by device type and speed threshold. For certain mobile or section-control settings, reported corrections are 7 km/h below 100 km/h and 7% above that threshold; fixed equipment may follow different tolerances.
Context and Implications
Spain’s enforcement network reflects a wider European use of automated road-safety measures. The DGT’s published location information identifies control points by province, road, kilometre point and direction. Public debate continues over privacy, camera visibility and revenue. Fine totals and citation counts describe enforcement output; on their own, they do not measure road-safety outcomes.
The European Transport Safety Council has said that countries with widespread speed-camera use have recorded impressive declines in road fatalities over the past decade. For Spain, the international review provides evidence that automated enforcement can change driving behaviour, while its pooled 7.57 km/h estimate should not be mistaken for a measured effect at every Spanish camera. Respecting speed limits remains basic to reducing risk for drivers and other road users.
