Spanish drivers face new mobile speed trap: the towable radar
Forget static speed cameras – Spanish authorities are deploying a new wrinkle in traffic enforcement: towable radar units. These mobile marvels, capable of issuing up to 20 tickets per minute, are already appearing on the A-1 highway, adding a new layer of complexity for drivers already wary of speed traps.
A hybrid approach to speed enforcement
These aren't your average mobile radars. They sit somewhere between a fixed and a roving unit, towed by a vehicle and capable of relocating swiftly to different points along the road. This constant movement makes predicting their location virtually impossible, a deliberate design choice by the Dirección General de Tráfico (DGT), Spain's traffic authority.
The shift comes as speedingremains the leading cause of traffic violations in Spain, with traditional fixed, mobile, and section control radars proving insufficient. The DGT reports a staggering 15,000 fines issued last year alone in construction zones – areas where drivers frequently disregard reduced speed limits while workers are present. The towable radar aims to curb this dangerous behavior, prioritizing worksites as a prime deployment location.
Currently, one of these units is stationed on the A-1, also known as the Autovía del Norte, near exit 45 in the southbound direction. While its current location is at a construction zone with a maximum speed limit of 100 kilometers per hour, authorities stress its mobility, indicating that it, and others like it, will be appearing at various locations across the national road network.
What’s particularly unsettling is the radar's discreet appearance; it’s designed to blend in and be difficult to spot from a distance. Coupled with the unpredictable locations, spotting one of these devices before it’s too late is a significant challenge for even the most vigilant drivers. The Technology itself boasts impressive capabilities: a battery life of up to two weeks and a direct internet connection for immediate transmission of speeding violations to traffic authorities.
But the innovation carries a cost. While the DGT insists this is about safety, the sheer volume of potential tickets – one every three seconds, according to their estimates – raises concerns about revenue generation. Whether this new strategy will genuinely improve road safety or simply become a lucrative source of income remains to be seen.

Beyond the a-1: expect more towable radars
The A-1 deployment is just the beginning. Expect to see these towable radar units becoming increasingly common across Spain’s highways. Drivers are urged to exercise caution, strictly adhere to speed limits, and remain vigilant – because the next speed trap might just be pulling up behind you.
