In the road freight transport sector, keeping up to date with road regulations is key to ensuring safe and efficient operations. At Fernández Aedo, specialised in tank trucks and the transport of chemical liquids and ADR, we know that road safety not only protects our loads, but also our drivers and the environment. That is why, in this article, we review the most relevant developments in road signage in both Spain and France in 2025.
⮞ Spain
1. Green and blue lines on roads
The Dirección General de Tráfico (DGT) has implemented new horizontal signs such as green lines, which warn of dangerous stretches of road, and blue lines for areas with special restrictions. This especially affects common routes for the transport of chemical products, where extra caution is required.
This measure is especially relevant for companies such as ours, which operate routes with tanks for hazardous liquids, as it improves anticipation of conflictive stretches.
2. Intelligent signs for cyclists
The increase in cyclist traffic has prompted the installation of signs that detect their presence. On routes shared with heavy vehicles, these technologies allow our tankers to adapt their driving to changing situations.
3. Mandatory replacement of triangles by V-16 lights (2026)
Although the measure will be mandatory in 2026, the use of V-16 devices connected to the DGT 3.0 platform is already being promoted in 2025. For fleets of commercial vehicles and dangerous goods transport, this measure represents a crucial improvement in emergency response and signalling times.
⮞ France
1. Hydra Noise Radar
France has started to penalise vehicles exceeding 85 dB. This noise pollution control has a direct impact on international transport. For companies like Fernández Aedo, with a modern and efficient fleet, this represents a competitive advantage on European routes.as.
2. C-ITS system: vehicle-infrastructure communication
Technological innovation in the transport sector is taking a leap forward with the C-ITS system, which allows vehicles to receive real-time information about traffic, road works or hazardous conditions. For trucks carrying corrosive or flammable liquids, this technology significantly increases safety.
3. Low Emission Zones (LEZ)
More than 30 French cities have activated access restrictions according to the Crit’Air label. This directly affects international road transport, requiring fleets to be environmentally friendly.
These new signalling measures are not just regulatory changes: they are steps towards more modern, safer and more sustainable transport. At Fernández Aedo we remain committed to innovation in the transport of dangerous goods, continuously adapting to the challenges of the European market.
