Largest motorbike or scooter you may ride on a car licence

Important

UK · home

Engine up to 50 cc

A full car licence lets you ride a moped up to this engine size without L plates or a moped test. If you passed your car test on or after 1 February 2001 you must first complete a compulsory basic training (CBT) course. Anything larger needs CBT and the motorcycle tests. The Highway Code's Annex 2 defines the two-wheeled moped class by a maximum design speed of 45 km/h (28 mph) rather than by engine size; that figure is not on the page cited here. Stated for licences issued in Great Britain; the source does not say whether foreign car licences get the same allowance.Checked 2 Sep 2026

Portugal · destination

Engine up to 125 cc
Power up to 11 kW

A category B licence counts as a licence for motorbikes within both limits at once (the A1 class), but only if the holder is 25 or older, or already holds a moped licence. Nothing has to be added to the licence. The IMT page does not say whether this applies to foreign car licences.Checked 2 Sep 2026 · official source

Portugal · destination14 yearsThe normal age is 16. From 14 a moped licence is possible only after a special training course approved by the IMT and passing the test. Under 18 needs written permission from a parent. Mopeds are up to 50 cc.Checked 2 Sep 2026 · official source

Smallest motorbike allowed on the motorway

Good to know

UK · home

Engine at least 50 cc
Power at least 4 kW

The rule is set by engine size, not vehicle class: riders of motorcycles under 50 cc (4 kW) must not use motorways, so a machine of exactly 50 cc is allowed. The Highway Code gives the power figure in brackets as the equivalent of the engine size rather than as a separate test. Riders holding only a provisional motorcycle licence must not use motorways either.Checked 2 Sep 2026

Portugal · destination

Engine at least 50 cc
Top speed at least 60 km/h

Article 72 of the Código da Estrada bans mopeds, and motorbikes of 50 cc or less, from motorways and their access roads, so exactly 50 cc is out and the machine must be over 50 cc. It also bans any vehicle that cannot go faster than 60 km/h on a flat road, so the machine must be able to exceed 60 km/h. Both figures are in the article itself. A moped is defined in article 107 of the same code as at most 45 km/h, 4 kW and 50 cc, which the two thresholds above already cover, including electric machines.Checked 2 Sep 2026 · official source
