On August 12, Spain will experience a total solar eclipse for the first time since 1905, drawing residents and visitors toward the path of totality. The event is expected in the evening, with totality around 20:30 in several Spanish locations. NASA’s eclipse calculations estimate a maximum duration of about 2 minutes 18 seconds and a maximum path width of roughly 294 kilometres. The eclipse’s greatest point will occur at 17:45:53.8 UTC, at approximately 65.225° N, 25.228° W, far from Spain.
The Dirección General de Tráfico (DGT) has classified the eclipse as an Event of High Impact on Traffic (EVAAT) and is preparing for increased travel to viewing areas. Estimates cited from the Ministry of Economy, Commerce and Enterprise project between 400,000 and 1.5 million additional journeys, traffic increases of 30% to 100% in affected areas, and more than 446,000 extra visitors between August 10 and 16, including visitors from abroad. The narrow corridor of totality and its brief duration could concentrate demand on particular roads and access points.
Critical Safety Advice
For drivers on the road during the eclipse, the DGT’s basic advice is not to stop on a carriageway, motorway shoulder or other unauthorized location to watch. Stopping in such places creates a collision risk and can obstruct emergency access. Anyone wishing to observe should first reach a legal, safe parking place away from moving traffic.
Drivers should plan journeys well in advance and avoid unnecessary travel. They must never use a mobile phone, camera or other handheld device to capture the eclipse while driving. They should not look at the Sun or use eclipse glasses behind the wheel, since either can impair vision and divert attention from the road. Spain’s existing traffic rules on distracted driving and stopping in dangerous or unauthorized places apply throughout the event.
Totality is expected at about 20:28 in León, 20:29 in Zaragoza and 20:32 in Valencia. The Moon’s shadow moves across Earth at roughly 3,700 km/h, so the period of darkness passes quickly. The eclipse will occur close to sunset, when low-angle sunlight can cause glare before and after totality. Drivers should use the vehicle’s sun visor when needed, leave extra following distance and adjust speed to visibility and road conditions.
Special Attention to Eyewear
The DGT cautions against wearing sunglasses during the total phase, when sudden darkness can make the road difficult to see. Eclipse glasses should never be used while driving: they are designed for observing the Sun while stationary and can sharply reduce visibility of traffic and surroundings.
When the Sun reappears low on the horizon after totality, glare can return. Drivers should keep their attention on the road and use the vehicle’s sun visor as necessary. Eclipse viewing should take place only when parked safely.
Enhanced Traffic Control
To manage the expected influx of vehicles, the DGT plans to monitor traffic in real time from its control centres, with aerial units providing updates. The Guardia Civil’s traffic division is expected to increase patrols on basic routes leading to observation areas. Officers will focus on preventing illegal parking on shoulders and access roads, directing traffic where needed to keep routes clear for emergency vehicles. Preventive alcohol and drug checks are also planned at basic points.
Depending on conditions, authorities may introduce temporary traffic regulations, restrict access to particular locations, establish alternative routes and enforce capacity limits. Variable-message signs will inform drivers about incidents, restrictions and recommended routes during the event.
Context and Significance
The path of totality is expected to cross 13 autonomous communities: Galicia, Asturias, Cantabria, País Vasco, Navarra, La Rioja, Castilla y León, Comunidad de Madrid, Castilla-La Mancha, Aragón, Cataluña, Comunidad Valenciana and the Balearic Islands. The track crosses the northern Iberian Peninsula before continuing over the western Mediterranean; areas outside it will see a partial eclipse. The narrow totality corridor helps explain why visitors may converge on a relatively small number of viewing locations.
For road users, concentrated travel, a brief period of darkness and sunset glare make advance planning particularly impressive. The DGT advises anyone planning to observe the eclipse to reach their destination well before it begins, park legally and safely, and follow traffic-control instructions. Drivers should not attempt to watch or photograph the event while moving, or stop on a road or shoulder to do so.
