Driving in the UK (2026): cameras, speed limits and clean-air zones

The UK is one of the easiest places to road-trip, but it has two “gotchas”: speeds are in mph and camera enforcement is common (including average-speed zones). Add roundabouts and left-side driving, and a little prep goes a long way.

Reminder: UK limits are in mph. Always follow posted signs (especially in roadworks and 20 mph zones).

Common enforcement types

  • Fixed cameras (rear-facing Gatso, front-facing types in some areas).
  • Mobile enforcement (camera vans and roadside checks).
  • Average-speed systems (often used in long roadworks).
  • Red‑light cameras at busy junctions.

Speed limits: quick reference (cars)

Limits vary by vehicle type and signage. As a simple starting point for cars:

  • Built‑up areas: often 30 mph (many 20 mph zones).
  • Single carriageway: commonly up to 60 mph where signed as the national speed limit.
  • Dual carriageway & motorway: commonly up to 70 mph.

Clean Air Zones (CAZ), ULEZ and city charges

Several cities apply Clean Air Zones and/or charges (e.g., London’s ULEZ and congestion charging). These are typically enforced with ANPR cameras. If you’re renting or driving a foreign vehicle, check requirements before entering.

Tolls and payment

The UK has fewer toll roads than many countries, but some bridges/tunnels and specific routes charge (often cashless). Plan ahead so you don’t miss a payment window.

Recommended Speed Camera Map setup

  • Set units to mph and enable voice alerts.
  • Turn on fixed, mobile and average‑speed alerts.
  • Use a slightly longer warning distance on motorways and in long roadworks.
