Working out who owns the road
Maintenance depends on the type of road, and this split resolves most of the confusion:
- Municipal roads and urban streets: the câmara municipal. This covers the overwhelming majority of streets where people live
- Non-tolled national roads, the Rede Nacional Rodoviária: Infraestruturas de Portugal
- Concessioned motorways: the company operating that stretch
How to tell which you are on
If you are on a street with pavements, houses and a street name, it is almost certainly municipal. If the road is marked "N" plus a number (N125, N222), it is a national road and therefore Infraestruturas de Portugal, unless it has been declassified and transferred to the municipality, which happens reasonably often.
On a tolled motorway the responsible party is the concessionaire, and the name is on the signage and gantries.
When in doubt, report to the council. If it is not theirs, they know whose it is. It does not work in reverse: Infraestruturas de Portugal will not forward a residential street pothole to the municipality for you.
What the report should contain
- Exact location: coordinates, or the kilometre marker on a national road, or street and nearest number
- Direction of travel and lane, on multi-lane roads
- Rough size and depth. "A wheel fits in it" is more useful than "big"
- A photo with something for scale and enough surroundings to locate it
- Whether it is signed or not. An unsigned pothole is a different risk, and that is what supports liability if it causes damage
- Whether it has already caused damage to anyone, as far as you know
If a pothole damaged your vehicle
Where the responsible body fails to maintain or adequately sign the road, extracontractual civil liability can arise. We cannot tell you whether your case succeeds, since that turns on proving a failure of diligence, but we can tell you what to gather, and this is where most people lose the case before starting it.
- Photograph at the scene: the pothole, the absence of signage, the damage, and a wider shot linking all three
- Call PSP or GNR to record the incident. Without an authority record at the time, proving where and when it happened is very hard afterwards
- Take witness contacts if there are any
- Keep the repair invoice
- Send a formal claim to the responsible body with all the evidence
A pothole is not litter, but the pattern is the same
Potholes recur in the same place for the same reasons: poor drainage, a trench badly reinstated after works, heavy traffic on a road never built for it. A filled pothole that reopens three months later is not bad luck, it is a symptom.
A single report gets a repair. A dated, photographed series at the same point over a year is what supports a request for proper intervention, and what strengthens a damages claim if the problem was already known and remained unsigned.

Council or Infraestruturas de Portugal?
It depends on the road type: municipal streets and roads are the council's; non-tolled national roads are Infraestruturas de Portugal's; concessioned motorways belong to the concessionaire. When unsure, start with the council.
Is it worth claiming for a tyre?
It can be, but it depends entirely on evidence. Without a PSP or GNR record at the time and photos at the scene, proving where and when the damage happened is very difficult.
What if the pothole is already signed?
Report it anyway if it is worsening or if the signage has disappeared. Signage reduces the body's exposure to liability; it does not fix the hole.
