Can a Diesel Euro 4 2010 Car Enter London? No — £12.50/day (cars), £10

A Diesel Euro 4 vehicle from 2010 cannot enter London — the ULEZ requires minimum Euro 6 for diesel. Non-compliant entry risks a £12.50/day (cars), £100/day (trucks) fine.

Can a diesel Euro 4 car enter London?

No. A diesel Euro 4 vehicle from 2010 does not meet London’s ULEZ standard, which requires a minimum of Euro 6 for diesel vehicles. Driving into the zone without an exemption is an offence.

The penalty is £12.50/day (cars), £100/day (trucks). London enforces the zone with anpr camera network, operating 24/7. A notice can still reach your home address, because authorities use commercial address-tracing services. What does not exist is automatic EU enforcement — Directive 2015/413 covers only eight road-safety offences and emission-zone violations are not among them.

Could your car still qualify? Check the exemptions

Some vehicles enter London’s zone legally even without meeting the Euro standard. The recognised exemptions are:

• Electric vehicles
• Disabled tax class vehicles
• Military vehicles
• Historic vehicles (1977 or older)

If your diesel Euro 4 car falls into one of these categories (for example a registered historic vehicle), you may still be allowed in — confirm with the zone operator before relying on it.

If you can’t enter: what to do instead

• Park & Ride. London and most United Kingdom cities run Park & Ride sites just outside the ULEZ boundary, typically a few euros per day plus a public-transport ticket — far cheaper than the £12.50/day (cars), £100/day (trucks) fine.
• Hire a compliant car. If you’re visiting, a rental that already meets the Euro 6 standard removes the problem entirely.
• Day pass / temporary permit. Some zones sell short-term permits for non-compliant vehicles — check the official London portal for current 2026 options.

How London’s ULEZ is enforced

The zone has been active since 2019 and is monitored by anpr camera network, 24/7. Cameras read number plates automatically and cross-check them against the emission register, so there is no practical way to “slip through” unnoticed. Fines are issued per entry, not per day — entering twice can mean two penalties.

Quick compliance checklist for London

• ✅ Confirm your Euro class on the CoC (not the model year)
• ✅ Obtain ULEZ compliant (£12.50/day charge if non-compliant) before entering
• ✅ Note the zone runs 24/7 — restrictions can apply outside peak too
• ✅ Keep proof of any exemption in the vehicle
• ✅ Budget for the £12.50/day (cars), £100/day (trucks) fine risk if unsure — Park & Ride is cheaper
