| Portuguese licence revalidation — medical certificate & expiry rules | For Group 1 categories (AM, A1, A2, A, B1, B, BE), a medical certificate (atestado médico) is required only from age 60: below 60 the revalidation is administrative and no medical certificate is needed. From 60, the atestado médico attesting fitness to drive is issued electronically by a doctor and transmitted automatically to the IMT (valid six months). Group 2 categories (professional — C, C1, D, D1 and their E variants) require a medical, and where applicable psychological, assessment at every revalidation. A licence expired for a longer period — generally more than two years — additionally requires passing a special driving examination (exame especial). |
