I got a fine a week ago in a school zone in Lisbon, I was doing 52 km/h in a road with a 40 km/h limit. The thing is, it was pretty dark and I didn't see the signage clearly. Do I have the right to appeal this fine or is it a lost cause?
The situation is tricky, but it's not impossible. The fact that you didn't see the sign by itself isn't an argument that'll hold up in court, like they said, because drivers are obliged to know the speed limits in school zones - that's in the law and the signage could've been there for years. However, if you can prove that the sign was damaged, covered in vegetation, or genuinely unreadable at that specific moment, then you do have grounds to appeal. Taking a photo of the location now (even if a week has passed) and documenting the condition of the signage helps.
The appeal follows a process: you have 15 business days from the date of notification to file a complaint with the National Road Safety Authority (ANSR). If that doesn't work out, you can then appeal to administrative court. But let's be honest, with 52 km/h in a 40 km/h zone at a school, your margin is thin. The fine will stick even if you appeal, unless you find something concrete about the signage.
Here's the trick nobody mentions: request a detailed report of the location where you got the fine - ANSR has to send you information about exactly where the sign was, what condition it was in, what equipment measured your speed. If there's any inconsistency in that report (for example, if the sign was 50 meters before the curve or if the speed-measuring equipment's calibration was out of date), then you've got arguments. A lot of people don't even know they can ask for this and end up not doing it.
You can always try to appeal, but you need solid arguments - "I didn't see the sign" rarely gets accepted because they assume you should have been paying attention to road conditions, especially in a school zone. What could help you is if you can prove the signage was actually deficient (photos, witnesses) or if there was a technical error in the speed measurement. The best approach is to contact a lawyer or the AMT (Autoridade da Mobilidade e dos Transportes) to find out if there's actually grounds for a formal complaint, because if you don't have anything concrete, the appeal could even hurt you with additional costs. Honestly, with 12 km/h over the limit it's a tough margin to defend.
But you need to have something concrete to base your appeal on - "I didn't see the sign" isn't going to convince anyone because the court expects you to pay extra attention in a school zone, regardless of lighting conditions. What *might* work is if you can prove the sign had a physical problem (it was damaged, hidden by vegetation, or the sign was actually missing from that specific location), or if you have evidence that the radar/speed enforcement had calibration issues. Otherwise, speeding by 12 km/h in a school zone is hard to justify - you can try, but mentally prepare yourself for the possibility that the fine will stand.
The others are right that "I didn't see it" is weak, but it's worth checking if the signage was actually adequate - if the signs were dirty, damaged, or the lighting in the zone was genuinely terrible, that changes things. Take photos of the location right now, during the day and at night, and see if you can get proof that the signage wasn't visible under the conditions it was in when you got the fine. If you can document that properly, then you've got an argument that isn't just "I didn't see it," it's "the signage was objectively invisible."
I've been through a similar situation and ended up dropping the appeal, but let me add a point nobody mentioned: if you can get evidence that the signage was actually deficient that night (missing lights, covered sign, etc.), it's really worth trying. The problem is that "I didn't see it" on its own doesn't work, but "the signage wasn't visible because of the road conditions" is different. If you want to take it to court, document the location properly, take photos and see if you can get data on the street lighting in that area - that could actually make a difference.
If you really want to try, the way to go is check whether the signage was actually in proper condition - dirty signs, faded ones, or poor lighting in a dark area are arguments that work better than "I didn't see it". I've seen people get fines cancelled that way, by documenting everything with photos. Now, "it was dark and I didn't see the sign" on its own won't convince anyone because the court assumes you should have reduced speed preventively in a school zone, regardless of visibility - that's the logic behind the fine.
Technically you have the right to appeal, but with 52 km/h in a 40 zone it's tough honestly - the margin is small and courts rarely overturn fines for that. Your weak point is exactly what you said, "it was dark," because they expect you to be attentive in school zones regardless of lighting conditions. What could actually work is if you can prove the signage was damaged, dirty, or that the zone itself has serious lighting problems - then you'd have something concrete to argue. If the sign was readable and conditions were normal, it's probably a tough case either way.
