Overview

• Operation Retorno runs from Friday at 15:00 to Sunday at midnight with intensified controls by Guardia Civil traffic agents, traffic centers, fixed and mobile radars, helicopters, drones, cameras, and camouflaged vehicles.
• Temporary measures include reversible or additional lanes, halted road works, limited road events, and time‑bound restrictions on certain freight traffic to ease congestion.
• DGT flags the busiest windows as Friday 16:00–22:00, Saturday 09:00–13:00, and Sunday 16:00–23:00, advising staggered returns to avoid jams on corridors from coastal areas to major cities.
• Regional forecasts highlight heavy flows such as 626,934 long‑distance movements in the Comunitat Valenciana, 212,500 in Murcia, and 149,000 in Asturias, with local advisories on peak hours and trouble spots.
• Amid the rollout of new signage, the S991f sign warns of minimum‑distance enforcement between vehicles, drawing online criticism over practicality as DGT has not detailed the detection technology; separately, new radars tested in August will begin issuing fines from September in regions such as Andalusia (part of a 122‑device 2025 plan, 32 already active).
