Can I use a dashcam in my car?
Conditional: it's a grey zone — there's no specific dashcam law. The CNPD's (data-protection authority) position is that continuous filming of the public road, plates and people from a car-mounted camera breaches Art. 19 of Law 58/2019 (Portugal's GDPR law). On the other hand, the household/personal exemption of the GDPR can cover someone recording purely for self-protection — provided the footage is not published or shared publicly. Lawfulness turns on the use: handing footage to police, courts or insurers is broadly tolerated and is admitted case-by-case; publishing identifiable third parties on social media is where liability bites. In short: personal-protection use yes, publishing no.
📋 The rules
- No specific law: the CNPD interpretation applies
- Continuous filming of the road: CNPD sees a GDPR breach
- Personal/household exemption if you don't publish
- Evidence for police/courts/insurers: tolerated
- Publishing identifiable third parties: risky
🔓 Exceptions
- Personal use for self-protection, without disclosure
- Handing footage to authorities as evidence: admitted case-by-case
- Publishing plates/faces on social media: where liability lies
⚠️ Penalties & fines
Under Law 58/2019/GDPR, fines run from €500 (individuals) / €1,000 (companies) up to the GDPR ceilings in theory. Beware two myths: "dashcams are simply legal" and "dashcams are banned and the footage is inadmissible" — both are oversimplifications. Portugal has no specific law, only the CNPD's GDPR-based interpretation (unlike Germany's explicit rules or Austria's near-ban). To stay compliant: use the dashcam for self-protection, don't publish footage with identifiable plates or faces, and hand any relevant recording directly to the police, court or insurer — that's where footage is admitted case-by-case.

❓ Frequently asked
Is it legal to use a dashcam in Portugal?
It's a grey zone. There's no specific law. The CNPD considers that continuously filming the public road, plates and people breaches the GDPR, but the personal exemption can cover someone recording only for self-protection who doesn't publish the footage. It all depends on how you use it.
Can I use the footage as evidence?
As a rule, yes, case-by-case. Handing footage to police, courts or insurers is broadly tolerated, and such recordings have been admitted as evidence. The problem arises when you publish the footage, with identifiable third parties, instead of handing it to authorities.
Can I publish the footage on social media?
It's risky. Publishing footage with identifiable plates or faces of third parties is precisely where liability arises under the GDPR. The personal exemption stops applying when there's public disclosure. The safest course is to hand footage only to authorities or insurers.
What's the CNPD's position?
The CNPD holds that continuous filming of the public road, with plates and people, from a car-mounted camera breaches Art. 19 of Law 58/2019. It doesn't expressly ban dashcams, but warns of GDPR limits, especially regarding disclosure of footage.
What's the fine if I infringe?
Under Law 58/2019 and the GDPR, fines start at €500 for individuals and €1,000 for companies, potentially reaching the GDPR ceilings in serious cases. The biggest practical risk is improper publication of third parties' footage.
