September speed checks sweep Portugal’s roads, expats warned

At a glance

Visitors and long-term residents who rely on Portugal’s road network will notice an unusually dense wave of speed-checks throughout September. Public safety officials released an indicative calendar that covers every district, from the beachfront Avenida Marginal in Cascais to rural lanes in the Alentejo, while simultaneously activating 37 new fixed cameras under the national SINCRO programme. Although the schedule can shift without notice, the publication offers a rare opportunity to plan drives—and avoid costly fines that start at €60 and climb above €600 when limits are exceeded by more than 60 km/h.

Why the police publishes the map every month

Portugal’s Polícia de Segurança Pública (PSP) insists the disclosure is not a “gotcha” tactic but part of the decade-old campaign Quem o avisa… (“He who warns you…”). By telling motorists where enforcement will occur, the PSP hopes to curb what it calls the single biggest contributor to fatal crashes: excessive speed. Analysts at the National Road Safety Authority say stretches equipped with cameras have recorded 36 % fewer collisions and 74 % fewer deaths compared with pre-radar periods.

Hotspots foreign drivers keep stumbling into

The master list released on 1 September runs for pages, yet several corridors matter disproportionately to expatriates and tourists.

Lisbon metropolitan area: Expect mobile units on the IC2 near Santa Iria de Azóia, the northbound climb of the 25 de Abril Bridge, and outside Humberto Delgado Airport’s Terminal 2 access road, where patrols operate most days until 18:00. Suburban Oeiras and Sintra will also see equipment on the Estrada Nacional 117 and the winding EN 250-1 at Algueirão.

Porto and the North: Radar vans return to the Estrada da Circunvalação in Matosinhos, Porto’s ring road notorious for sudden lane merges. Additional control points dot Avenida 25 de Abril downhill into the city, and the riverside route in Vila Nova de Gaia near the D. João II boulevard will host eight-hour sessions at month-end.

Algarve: Holidaymakers in rental cars should slow on the EN 125 through Olhão and Tavira, as well as Portimão’s bustling Avenida V6, which is under watch on both 16 and 17 September. An extra patrol returns to Vila Real de Santo António’s seafront on the 23rd.

Islands: In Madeira, crews will park equipment along the cliff-hugging VR-1 at Quinta Grande on 24 September, while in the Azores two afternoon traps are booked for Flamengos parish on Faial. Flights of inter-island visitors often rent cars, so keep those EU licence plates within limits.

Beyond the coast: interior roads join the clampdown

Central arteries such as Coimbra’s IC3 in Banhos Secos and Braga’s fast Avenida António Macedo appear repeatedly this month. The Beira Interior sees twin sessions on Covilhã’s Alameda Pêro da Covilhã, and the transmontano city of Vila Real inherits late-afternoon enforcement on Rua Vasco Sameiro.

Drivers cutting across the country toward Spain should note that Portalegre’s Avenida Extremadura Espanhola and Guarda’s Via da Cintura Externa are flagged on multiple dates. Even quiet wine routes around Estremoz and Lamego will host two-hour checks that have previously netted dozens of unsuspecting travellers.

How the fixed SINCRO network is expanding

On top of the monthly mobile timetable, the National Road Safety Authority switched on 12 average-speed cameras and 25 instant-flash devices at the start of September. This pushes the permanent network to 123 active locations, including fresh installations on the IC2 in Oliveira de Azeméis, the beach road EN 6-7 between Carcavelos and Parede, and the A43 approach into central Porto. Every SINCRO box is preceded by a blue sign, yet many newcomers still blend into urban streetscapes.

Dodging penalties without breaking the law

Portugal’s code allows on-the-spot collection of fines from foreign-plated vehicles. Carry at least €300 or a credit card to avoid a roadside immobilisation order. Digital allies such as Waze, Radarbot or the community-run Radares de Portugal app push real-time alerts, but remember that officers can set up surprise operations not listed in any database.

If you do receive a ticket, prompt online payment trims the surcharge, while contesting requires written Portuguese submissions within 15 days. Insurance premiums are rarely affected abroad, yet unpaid fines can surface at the rental counter on your next visit.

The road ahead

Officials hint at further technology—namely section-control radar in long tunnels and on the Algarve’s A22—but no budget line has been approved for 2026. Until then, September’s grid already covers every tourist corridor and commuter belt. Plan routes, respect posted limits, and treat each empty straight-away as though a camera is watching. The data suggest that simple precaution is saving dozens of lives every month.
