Largest motorbike or scooter you may ride on a car licence

Important

France · home

Engine up to 50 cc
Power up to 4 kW
Top speed up to 45 km/h

Permis B covers a moped (cyclomoteur) with no extra step; the AM category is not needed if you hold another category such as B. The source defines the class as two or three wheels, 45 km/h maximum, 50 cc maximum if it has a petrol engine, and 4 kW maximum motor power, so the engine cap is for petrol machines and the power cap applies to all. Riding a light motorbike or scooter up to 125 cc and 11 kW on permis B needs the licence held for at least 2 years and a 7 hour practical course, which gives a certificate. Holders of a European B licence must also do the course. The source does not say whether a non-European car licence gets the moped allowance.Checked 2 Sep 2026

UK · destination

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 · official source

What a rider must wear or carry

Important

Gloves

Rider and passenger must wear CE marked gloves. A hi-vis vest must be carried on the rider or the bike and worn if you stop on the road after a breakdown. The helmet must carry four reflective elements: front, back and both sides.Checked 2 Sep 2026

Who has priority at a roundabout

Good to know

Riding between lanes of slow traffic

Good to know

France · homeAllowed, with restrictionsLegal everywhere in France since 11 January 2025, but only on motorways and dual carriageways with a central reservation, at least two lanes each way and a limit of 70 km/h or more, and only when traffic is in continuous queues on all lanes. Ride between the two leftmost lanes at 50 km/h maximum, 30 km/h if one lane is stopped. Two or three wheelers up to 1 m wide only. No overtaking other filtering riders.Checked 2 Sep 2026

UK · destinationAllowedNo law bans filtering. The Highway Code tells riders to take care and keep their speed low when filtering in slow-moving traffic, and tells drivers to expect it.Checked 2 Sep 2026 · official source

Smallest motorbike allowed on the motorway

Good to know

France · home

Engine at least 50 cc
Power at least 4 kW
Top speed at least 45 km/h

The ban is by vehicle class: Code de la route article R421-2 lists cyclomoteurs among the vehicles refused access to motorways, with no figures of its own. The cited source is article R311-1, which defines a cyclomoteur as a two or three wheeler with a design speed of no more than 45 km/h, an engine of no more than 50 cc if petrol, and no more than 4 kW. A machine at exactly 45 km/h is still a cyclomoteur and stays off the motorway; one that is above ANY of the three caps is classed as a motorcycle and may enter, so a machine does not have to be above all three. Motor tricycles up to 15 kW and 550 kg unladen are also refused.Checked 2 Sep 2026

UK · destination

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 · official source
