What you must carry in the car

Critical
UK · homeNothing — no equipment is legally requiredNothing is legally required. Drivers arriving from most of continental Europe expect a triangle and a vest to be compulsory here; they are not.Checked 20 Aug 2026
Belgium · destination
  • Warning triangle
  • High-visibility vest
  • Fire extinguisher
  • First aid kit
Four items, which is more than most of Europe asks for. The extinguisher and the first aid kit are the ones visitors do not expect — check a hire car has both before you drive away. They go with the car's number plate rather than the driver, so they are required in a Belgian-registered car, hire cars included, and not in a car you drove in on foreign plates. One vest is required, for the driver, and must be worn if you leave the car on a motorway; vests for passengers are advised rather than required.Checked 19 Aug 2026 · official source

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
Belgium · destination
  • Engine up to 50 cc
  • Power up to 4 kW
  • Top speed up to 45 km/h
A Belgian category B licence includes category AM automatically, and the ministry's AM page defines the class it covers (bromfiets klasse B) as a two-wheeler with an engine of at most 50 cc and a design speed of between 25 and 45 km/h; the 4 kW limit is the power of an electric motor. The same inclusion is stated on the ministry's category B page. Riding a 125 cc motorbike (category A1, up to 11 kW) on a B licence needs code 372 added to the licence: B held for at least 2 years and issued after 30 April 2011, plus 4 hours of practical lessons at an approved driving school. Code 372 is valid in Belgium only. The ministry pages do not say whether foreign car licences get the moped allowance.Checked 2 Sep 2026 · official source

What a rider must wear or carry

Important
UK · homeNothing beyond a helmetNo law requires protective clothing beyond the helmet. Eye protection is advised, and if worn it must meet an approved standard.Checked 2 Sep 2026
Belgium · destination
  • Gloves
  • Protective jacket
  • Boots
Article 36 of the traffic code. Rider and passenger of a motorbike must wear gloves, a jacket with long sleeves, long trousers or an overall, and boots or ankle boots that protect the ankles. Long trousers are also required but are not in this list. The clothing rule is for motorbikes; it does not apply to mopeds.Checked 2 Sep 2026 · official source

Riding between lanes of slow traffic

Good to know
UK · homeAllowedNo 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
Belgium · destinationAllowed, with restrictionsArticle 16.2bis of the traffic code. A motorbike may ride between two lanes or queues of stopped or slow traffic. The rider may not go faster than 50 km/h, and may not go more than 20 km/h faster than the traffic in those lanes. On motorways and on roads for motor traffic only, the rider must use the gap between the two left-hand lanes. This applies to motorbikes, not mopeds.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
Belgium · destination
  • Top speed at least 70 km/h
Article 21.1 of the traffic code bans mopeds (bromfietsen) from motorways by vehicle class, and separately bans any vehicle or combination that cannot reach 70 km/h on a flat road. The article states no engine size, so 70 km/h is the only threshold written. Article 2 defines a moped as at most 50 cc, 4 kW and 45 km/h by design, so every moped also fails the speed floor; a two-wheeler that can reach 70 km/h is a motorbike and may enter. Article 21.2 then sets 70 km/h as the minimum speed to ride at.Checked 2 Sep 2026 · official source

Headlights on a motorbike in daytime

Good to know
UK · homeNot requiredDipped headlights in daylight are advised to make the rider easier to see, but they are not required.Checked 2 Sep 2026
