This article provides guidance for expats in Portugal whose foreign driver's licenses have expired. It emphasizes that an expired license cannot be exchanged for a Portuguese one; renewal must be completed first. If caught driving with an expired license, fines up to €600 apply, and drivers should immediately stop driving and use public transportation. To renew, expats should contact their home country authorities (e.g., DVLA for the UK) and may need to use a proxy address. Alternatively, they can opt for a full driving test, which involves over 32 hours of lessons and costs €600+. The article stresses the importance of starting the exchange process early within the allowed 185-day or 2-year window to avoid legal issues and delays. It highlights that timely action is crucial to prevent disruptions to travel and daily life in Portugal.
