Car insurance validity when travelling abroad – Portugal
Comprehensive cover when travelling abroad
Your comprehensive car insurance policy (covering theft, vandalism, legal costs, etc.) is valid for a period of the period for which it was signed (usually 1 year) when travelling in another EU country (if the parties agree, which is the usual proceduure).
Insurance cover for additional drivers when travelling abroad
Anybody can drive the insured vehicle at any time, not just the owner (authorized by the owner).
This does apply to family members living in the same household (however, this type of drivers is presumed to be authorized to that effect.
Trailers must be insured
The standard insurance policy in Portugal for vehicles also covers the trailer (if the policyholder so requests and with the identification of the trailer in the policy).
As a national of another EU country travelling with a trailer in Portugal, you do not need to take out a separate policy for the trailer (if the trailer is already covered by a policy of the EU country of origin).
