Accident on the N-523 between Cáceres and Badajoz: one dead and several injured after a multiple collision

In Spain, the investigation of accidents on state roads (network owned by the General State Administration) usually corresponds to the Traffic Group of the Civil Guard. Although there are nuances depending on the severity of the accident and the internal protocols of each command, the basic scheme is relatively homogeneous and is based on the Road Safety Law, the General Traffic Regulations, and the Criminal Procedure Law.

1. Activation and arrival at the accident site

The procedure normally begins with a call to 112 or the traffic control center (COTA). From there, the traffic patrols of the Civil Guard are mobilized and, if appropriate, medical teams and firefighters. Upon arrival, the first priority is not to “investigate” but to:

• Secure the area: signaling with triangles, cones, vehicles with priority lights, and, if necessary, lane closures or detours.
• Assist the victims: initial assessment, basic resuscitation, and coordination with health services.
• Prevent new risks: avoid fires, fuel spills, chain collisions, etc.

2. Scene delimitation and initial data collection

Once the emergency situation is stabilized, the purely investigative phase begins. Traffic patrols or, in serious accidents, the Accident Reports and Investigation Teams usually:

• Delimit the scene so that braking marks, vehicle debris, final positions, etc., are not altered.
• Identify the drivers, occupants, and possible witnesses, noting their personal and contact details.
• Collect basic information about the vehicles: license plate, owner, insurer, visible damage, tire condition, lights, etc.

3. Alcohol, drug tests, and documentation

As part of the standard protocol:

• Alcohol tests are performed on the involved drivers and, in many cases, drug tests as well.
• Documentation (driving license, ITV, mandatory insurance) is checked and any irregularities are recorded.
• In case of refusal to undergo tests or clear indications of a crime, the driver is informed of their rights and criminal proceedings are initiated.

4. Technical inspection of the accident site

The most “technical” part of the investigation is carried out by the reports team when the accident is serious or fatal. Common actions include:

• Preparation of a sketch and taking photographs or video from various angles.
• Measurement of distances, braking marks, skids, and positions of vehicles and victims.
• Collection of relevant material remains (plastics, glass, paint) and securing mechanical elements if technical failure is suspected.
• Verification of the road condition: signage, lighting, superelevation, pavement, weather, obstacles, etc.
• In professional vehicles, checking tachographs or electronic recorders, if present.

5. Statements and reconstruction

At the scene or later in official premises, officers take:

• Statements from drivers and witnesses, recorded in writing and signed.
• Additional data on insurance, owning companies, transport companies, etc.

With all this, the team can carry out a technical reconstruction of the accident dynamics (trajectories, estimated speeds, prior maneuvers), sometimes supported by software or specialized experts, especially if it is a fatal or particularly complex accident.

6. Preparation of the report and submission to the judicial authority

The result of all the work is reflected in the report, which is the official investigation document. It usually includes:

• Chronological account of the facts and police actions.
• Description of the road, vehicles, and damages.
• Results of alcohol and drug tests.
• Sketches, photographs, and measurements.
• Statements and witness data.
• Conclusions on probable causes and observed infractions.

The report is sent to the Guard Court or the corresponding court by jurisdiction and serves as the basis for criminal proceedings or to determine administrative and civil responsibilities. At the same time, the data may be used by insurers in processing claims.

7. Particularities and variations

Although this is the general scheme, there may be variations depending on:

• The severity of the accident (minor with only material damage vs. fatal).
• The existence of crimes (positive alcohol test, reckless driving, hit and run, etc.).
• The need for complementary expert reports (civil engineers, vehicle experts, etc.).

But essentially, the usual procedure of the Traffic Civil Guard combines immediate assistance, securing the scene, systematic data collection, and a technical investigation aimed at determining causes and responsibilities with legal guarantees.

For a conventional state road like the N‑523 to become part of the highway network (for example, as A‑58), it is not enough to just “add a dual carriageway”: it must meet a set of legal (classification and procedure) and technical (design, capacity, and safety) requirements mainly established in the Road Law 37/2015, the General Road Regulations, and the technical standards of the Road Instruction.

1. Legal and classification requirements

Law 37/2015 and its regulations define the classes of roads and the State Road Network. According to the former article 2 of the General Road Regulations (RD 1812/1994, now replaced but still useful as reference):

• Motorways: exclusive automobile traffic, no access to adjoining properties, no level crossings, and separated carriageways.
• Highways: roads that, without meeting all motorway requirements, have separated carriageways for each direction and restricted access to adjoining properties, without level crossings with other roads.
• Conventional roads: those that do not meet the above (typical case of an N‑… road).

The Regulation itself establishes that when, as a result of works, a road acquires the characteristics of another class (for example, from conventional to highway), it legally acquires that status after processing an official file by the Directorate General of Roads:

• The file certifies that the physical and functional requirements of a highway are met.
• Descriptive plans and a justificatory report are included.
• Reports are requested from affected autonomous communities and municipalities (with possibility of public information).
• The change of class and, if applicable, inclusion in the State Road Network, is approved by the competent Ministry and, if it implies change of ownership or network, by Royal Decree of the Government.

Additionally, Law 37/2015 establishes that state roads in the Network must:

• Be part of itineraries of general interest or affect more than one autonomous community.
• Primarily serve long-distance traffic, not just local distribution.
• Be integrated into the State Road Plan or road programs approved by the Government.

2. Technical design requirements for a highway

The specific technical standards are set in the Road Instruction norms, particularly:

• Standard 3.1-IC “Alignment”, approved by Order FOM/273/2016.
• Standard 6.1-IC “Pavement sections”, approved by Order FOM/3460/2003.
• Other specific standards (tunnels, signage, drainage, pavement rehabilitation, etc.).

Based on these, a road that wants to be classified as a highway must, in general terms:

• Typical section of separated carriageways by median or other physical separation system, with at least two lanes per direction in most cases of the basic network.
• Paved shoulders wide enough for safety and incident management.
• High design speed (usually 100–120 km/h), which conditions:
• The minimum curve radii in plan.
• The maximum gradients in profile.
• Visibility lengths and overtaking or stopping distances.
• Capacity adequate to the expected heavy traffic intensity (categories T00–T4 of Standard 6.1-IC), with pavement sections sized for that load during the pavement’s service life.
• Pavements designed according to Standard 6.1-IC: layered structure (subgrade, subbases, bases, and wearing course) adapted to traffic and soils, with special attention to durability and maintenance.
• Elimination of direct accesses to adjoining properties and strict control of new connections, replacing them with:
• Grade-separated interchanges, with ramps and collector-distributor roads when necessary.
• Service roads alongside to provide access to urban, industrial, or agricultural areas without entering the highway directly.
• No level crossings with other roads or railways: all crossings are grade-separated.
• Adequate road safety elements: barriers, signage, delineation, drainage, margin treatment, etc.
• Compliance with specific standards for tunnels on state roads, when present.

3. Administrative and environmental procedure

Before executing the works that will convert an N‑… into a highway, the regulations normally require:

• An informative study that analyzes route alternatives and justifies the solution, subject to public information and environmental assessment (ordinary or simplified, depending on the case).
• Reports from affected administrations (autonomous communities, municipalities, environmental bodies, etc.).
• Approval of the informative study by the Ministry of Transport (or the one with road competencies).
• Drafting and approval of the construction project, already adjusted to Standards 3.1-IC, 6.1-IC, and other technical standards.
• Tendering and execution of the works; reception, commissioning, and finally, formal classification as a highway through the class change file and, if applicable, modification of the State Road Network.

In summary, integrating a road like the N‑523 into the highway network (A‑58) requires that, besides functionally belonging to a state itinerary of general interest, it be physically transformed and legally processed to meet the design, capacity, safety, and environmental protection standards imposed by state road legislation on highways.

The latest regional elections in Extremadura were held on December 21, 2025, following the early election called by María Guardiola. These elections completely redrew the political map of the community, consolidating a clear dominance of the right-wing bloc, but without an absolute majority for the PP alone. At the same time, in the provincial capitals, Cáceres and Badajoz, the Popular Party also governs at the municipal level, although with very different configurations.

Results of the latest regional elections in Extremadura (21-D 2025)

With more than 90 % counted, the 2025 regional elections resulted in the following distribution of seats in the Extremadura Assembly (65 deputies in total, absolute majority at 33):

• PP: 29 seats and around 43.1 % of the votes. This was an improvement compared to 2023 (when it had 28 deputies), but it fell 4 short of an absolute majority. Source: Demócrata election results analysis ( election coverage).
• PSOE: 18 seats and around 25.8 % of the votes. It lost 10 deputies compared to the 28 it had after the 2023 regional elections, marking its worst historical result in the community.
• Vox: 11 seats and close to 16.9 % of the votes. It practically doubled its representation compared to 2023 (when it had 5 deputies and just over 8 % of the vote).
• Unidas por Extremadura (UxE): 7 seats and around 10.25 % of the votes, clearly improving the 4 seats and about 6 % it had in 2023.

In terms of blocs, PP and Vox together hold a comfortable absolute majority, exceeding both the threshold of 33 deputies and 60 % of the combined vote. Hence, press reports speak of a “shift to the right” in Extremadura and of Vox becoming an essential partner for governance, even though the PP is clearly the hegemonic force in votes and seats.

This result is constantly compared with the regional elections of May 28, 2023, when PP and PSOE tied at 28 seats, but the socialists were then the most voted list. In 2025, the scenario reverses: the PP opens a gap of almost 18 points over the PSOE and 11 seats difference, consolidating María Guardiola’s presidency, who governs in coalition with Vox (something also reflected in the approval of the 2026 Budgets with a PP-Vox majority, according to parliamentary report).

Who governs in Cáceres

At the municipal level, available information indicates that the Cáceres City Council is governed by the PP. Various news sources identify Rafael Mateos as mayor of Cáceres, acting as mayor on behalf of the Popular Party in diverse municipal matters such as the application of the Democratic Memory Law or support for local economic sectors (for example, his participation in a forum on the tobacco sector covered by Demócrata: coverage on the Cross of the Fallen and tobacco forum).

Additionally, a report by eldiario.es on the budget situation of Spanish cities explicitly places Cáceres with a “PP minority government”, which must negotiate its budgets with the rest of the municipal plenary groups ( analysis on municipal budgets). That is, the PP holds the mayoralty but does not have an absolute majority and needs the support — or at least abstention — of other forces to pass key decisions such as the budgets.

Who governs in Badajoz

In Badajoz, the Popular Party also governs, but in a different scenario than in Cáceres. The cited eldiario.es article points out that in Badajoz the PP “enjoys an absolute majority” in the city council, which gives it much greater room to approve its budgets and municipal projects without depending on agreements with the opposition.

The mayoralty is held by Ignacio Gragera (PP), who appears as mayor of Badajoz in various recent institutional events, for example in economic forums where he advocates for investments and cross-border cooperation with Portugal ( Gragera’s intervention). The same context confirms that the PP comfortably controls the Badajoz city council during the current municipal term.

In summary, after the latest 2025 regional elections, Extremadura is configured as a community clearly leaning to the right — PP and Vox hold a solid majority in the Assembly — and its two provincial capitals, Cáceres and Badajoz, are also governed by the Popular Party, although with different formulas: PP minority in Cáceres and PP absolute majority in Badajoz.
