These are the places where the DGT plans to ban the circulation of cars with fewer than two occupants.

The General Directorate of Traffic ( DGT ) is considering banning the circulation of cars with only one driver. This measure is inspired by European HOV lane policies and would help reduce traffic in already congested Spanish cities. For now, the measure is under review, although it is worth considering the cities where it would be implemented, if approved.

The cities where this measure would be implemented would be those that are overwhelmed by traffic. That is, cities like Madrid, Barcelona, Valencia, and Seville . However, it should be noted that, in principle, the DGT could only regulate access to these cities, but could not prohibit the use of only one person per vehicle in urban centers.

The reason behind this is that city mobility depends on municipal ordinances , which regulate traffic restrictions. For the ban to become widespread, city councils must have a legal framework to support the Traffic Department's decision, just as is already the case with the low-emission zones required for municipalities with more than 50,000 inhabitants.

This isn't the only measure the DGT is considering. Other proposals include limiting the number of cars allowed per household to one car or charging one euro a day for non-resident vehicles traveling on some Spanish roads, as is already the case in the Balearic Islands. Time limits and other prior access controls are also planned for the archipelago.
