Oxford's traffic filters: what they mean for your commute

What are the Oxford traffic filters?

Traffic filters (sometimes called "bus gates") use ANPR cameras to stop most private cars from driving through certain points in the city. Buses, taxis, cyclists and some other exempt vehicles can still pass, but ordinary through-traffic is redirected onto the ring road.

The aim is to cut congestion in the city centre and reduce air pollution, following years of consultation by Oxfordshire County Council.

Which roads are affected?

There are six traffic filters across Oxford, enforced by ANPR cameras:

• Hythe Bridge Street, St Cross Road, Thames Street and St Clement's — active every day, 7am to 7pm.
• Marston Ferry Road and Hollow Way — active Monday to Saturday, 7am to 9am and 3pm to 6pm.

Outside these hours you can drive through freely.

Fines and enforcement

If you drive through an active filter without a pass, an ANPR camera logs your number plate and Oxfordshire County Council sends you a fine.

• The penalty is £70, reduced to £35 if paid within 21 days.
• Unlike the earlier congestion charge, there is no £5 fee to drive through — you either have a pass or you don't.

Who is exempt?

The filters target private cars. Vans, motorbikes, mopeds, scooters and lorries are all exempt and can pass through freely.

Resident permits

Free passes to drive through the filters depend on where you live:

• Oxford city residents: 100 free passes per car, per year (up to three cars per household).
• Rest of Oxfordshire (including Kidlington): 25 free passes per car, per year (up to two cars per household).

Free permits are also available on request for Blue Badge holders, disabled tax-class vehicles, community health and care workers, unpaid carers, frequent hospital patients, firefighters, taxi and private hire drivers, car clubs, goods vehicles, driving instructors, and hearses or funeral cars.

How to apply

Permits are virtual — you don't get a physical permit to display, the cameras just read your number plate.

1. Go to the Oxfordshire County Council permit page.
2. Create an account (you'll need an email address) and add your vehicle.
3. Choose your permit type — Oxford city resident or Oxfordshire resident — and submit your proof of address (the page lists which documents are accepted, such as the V5C logbook).

If you already held a congestion-charge permit, it was transferred automatically — you don't need to reapply.

How it affects your commute

If you used to drive through the city centre, your route may have changed overnight — and the new restrictions can catch you out if you're on autopilot. The biggest risk is a penalty notice for a road you've driven for years.

Even if you don't get a fine, the filters have pushed more traffic onto surrounding roads, changing journey times across Oxford.
