Driving in the UK in 2026 is largely about three things tourists don't see coming: the patchwork of urban speed limits that now varies by nation, the spread of camera-enforced charging zones in English cities, and the gulf between Scottish and English drink-drive limits. Speeds are still posted in mph — 30 mph in built-up England, Scotland and Northern Ireland, 60 mph on single carriageways, 70 mph on dual carriageways and motorways — but since 17 September 2023 the default urban limit in Wales is 20 mph on any "restricted road" (a road with streetlights spaced no more than 200 yards apart).
Scotland is on the same path: a national 20 mph strategy is rolling out through 2026, with Glasgow starting on 4 June 2026 across roughly 3,800 streets and Inverclyde already switched over in April.
Driving on the left is just how the country works; the bigger trap for foreign drivers is the camera estate. London's Congestion Charge runs Monday–Friday 07:00–18:00 and Saturday–Sunday 12:00–18:00, currently £18 a day if you pay on time.
On top of that the ULEZ — expanded on 29 August 2023 to cover all 32 boroughs out to the M25 — bills £12.50 per day on non-compliant vehicles, 24/7. Outside London, Class D Clean Air Zones in Bristol (£9/day for non-compliant cars) and Birmingham (£8/day inside the A4540 ring) catch the most tourists; Bath, Bradford, Portsmouth, Sheffield and Tyneside operate Class C CAZs that don't charge private cars.
Parking enforcement is mostly civil, not criminal: a council PCN (Penalty Charge Notice) for an overstay is £80–£160 in London and £50–£70 outside, halved if paid within 14 days. That sits separately from criminal FPNs (Fixed Penalty Notices) issued by police — £200 and six points for handheld phone use under the March 2022 reform that closed the old "communications-only" loophole, £100 and three points for a red light, fines up to £500 for no seatbelt.
Regional quirks worth knowing: Scotland's blood-alcohol limit has been 50 mg/100 ml since 5 December 2014, against 80 mg/100 ml in England, Wales and Northern Ireland — cross the border and the same pint changes the law. The GB plate identifier was retired for international travel on 28 September 2021 (now UK).
And smart-motorway "all lane running" stretches on the M1, M6, M25 and M42 use variable mandatory limits on overhead gantries; the red-bordered number is legally enforceable, not advisory, even when the hard shoulder looks like a running lane.
