Average-Speed Zones in Europe: A Country-by-Country Guide
Average-speed enforcement has quietly become one of the most widespread road-safety tools in Europe. Instead of measuring your speed at a single point, these systems time your car between two or more cameras and calculate your average over the section. Cross a border, though, and everything changes: the local name, the typical road type, and how common the zones are.
This guide walks through seven countries with significant average-speed enforcement, using the known zones and camera locations bundled in our dataset. Counts change as authorities add and remove installations, so treat these as a current snapshot of publicly known locations rather than an official register.
Netherlands: trajectcontrole
The Netherlands is the densest average-speed country in our dataset, with 1,048 known zones alongside 887 known fixed cameras. The Dutch term is trajectcontrole, and it is a familiar part of the driving landscape: the systems are common on motorways and on the N-roads that connect towns, and Dutch authorities publish their locations openly.
Dutch limits also vary by time of day on some motorways, so the sign you pass entering a trajectcontrole section deserves a proper look, not a glance. For visitors, the practical habit is simple: note the limit at the entry sign, set a steady pace, and expect sections to be long enough that patience genuinely pays.
United Kingdom: average speed check
The UK has 1,004 known average-speed zones and 3,603 known fixed cameras in the dataset. British drivers know the zones by the distinctive yellow cameras on poles and the average speed check signs beneath them. They are especially associated with motorway roadworks, where temporary systems protect road workers with lowered limits, but permanent installations on A-roads and urban routes have grown steadily.
Because roadworks systems are temporary, UK zones appear and disappear more often than in most countries. The signage is the ground truth: if the boards say average speed check, assume the system is live.
Czechia: úsekové měření
Czechia runs 715 known zones, a strikingly high number next to its 441 known fixed cameras. The local term is úsekové měření, meaning section measurement. Czech systems are frequently municipal, placed on stretches through towns and villages where through-traffic meets pedestrians, rather than being concentrated on motorways.
For drivers, that means Czech average-speed zones often carry town-level limits. The zones are short, the limits are low, and a steady pace matters from the first sign.
Spain: radar de tramo
Spain has 298 known zones, called radar de tramo, alongside a large network of 2,030 known fixed cameras. Section control in Spain is particularly associated with tunnels, where a constant speed matters most for safety, as well as stretches of the national road network.
Spanish enforcement infrastructure is signposted, and tunnel sections deserve special respect: the combination of enclosed space and changing light is exactly where a calm, constant speed pays off. If you are driving to Spain on holiday, expect a mix of the two systems on one route, with spot cameras on open roads and section control where the road environment is least forgiving.
Belgium: trajectcontrole
Belgium shares the Dutch term trajectcontrole and has 276 known zones plus 1,319 known fixed cameras. Belgian authorities have expanded section control notably in recent years, on motorways and increasingly on regional roads through Flanders and Wallonia.
Belgium is a transit country for much of Europe, and many drivers pass through on long international journeys. If you are crossing Belgium, expect average-speed sections as a normal feature of the route, not an exception.
Italy: Tutor
Italy's motorway section-control system is known as Tutor, with 243 known zones in the dataset. What stands out is the fixed-camera figure beside it: 11,826 known fixed camera locations, by far the largest count in this guide. Tutor zones are a motorway phenomenon, covering long stretches of the autostrada network, while the fixed cameras blanket ordinary roads and towns.
The practical takeaway for Italy is to treat the whole network as monitored. On the autostrada, settle into a legal cruise; everywhere else, expect spot cameras to be frequent.
Poland: odcinkowy pomiar prędkości
Poland operates 236 known zones under the name odcinkowy pomiar prędkości, or sectional speed measurement, alongside 795 known fixed cameras. The national road-safety agency has grown the system steadily, with sections on expressways and on national roads passing through built-up areas.
Polish zones are clearly signposted with dedicated boards at the start of the section. As elsewhere, the sign marks the start of a timed distance, not a single camera position.
What this means for drivers
Two things are true everywhere in this guide. First, average-speed enforcement is growing, because the safety data behind it is strong: smoother traffic, fewer sudden braking events, fewer serious collisions. Second, the correct driving response never changes with the border: know the limit, pick a steady pace at or under it, and hold it for the whole section.
Crossing several of these countries on one trip means juggling different terms, different signs, and different limits. The Safe Average app carries these publicly known zones and fixed camera locations for all seven countries and shows your live average through a section, so an unfamiliar term on a foreign sign never has to translate into uncertainty behind the wheel.
Frequently asked questions
Are average-speed zone counts fixed, or do they change?
They change continuously. Authorities add new sections, retire old ones, and run temporary systems at roadworks. The figures in this guide are the publicly known locations in our current dataset, refreshed as sources update, and should be read as a snapshot rather than an official register.
Do fines from another EU country follow me home?
Often, yes. The EU cross-border enforcement directive lets member states exchange vehicle-owner data for speeding offences, so a fine incurred abroad can arrive by post at your home address. The dependable way to avoid that is the same everywhere: drive at or under the posted limit.
Why do some countries have far more fixed cameras than average-speed zones?
Section control is newer and more expensive per installation, since it needs at least two synchronised camera points and a surveyed distance. Many countries built large spot-camera networks first and are now adding average-speed sections where they help most, such as motorways, tunnels, and roadworks.
