Traffic filters: what you need to know
On Monday 28 September 2026, traffic filters replaced the temporary congestion charge. Changes to the way we travel can bring up lots of questions. In this blog, we explain what this means for people who drive in Oxford.
What’s happening?
The temporary congestion charge was introduced to help manage traffic during Network Rail’s extended closure of Botley Road.
Now the Botley Road has reopened, we can move ahead with the traffic filter trial as planned.
You will still be able to get by car to where you need to go, but you may need to use a different route if you do not have a permit for your car.
When is it happening?
Will I still be able to access everywhere in Oxford by car?
Yes. You will be able to drive a car to any part of Oxford without going through a traffic filter. If your usual route goes through a traffic filter while it is operating, you will need to take a different route unless you have a permit.
Read our ‘Travelling in and around Oxford’ and ‘Travelling to a hospital in Oxford’ blogs to find out more about other transport options.
Are there signs warning about traffic filters?
Yes, there are signs around the ring road directing people and warning signs before a you reach a traffic filter.
Why are we trialling traffic filters?
Oxford needs to reduce the number of cars on its roads to thrive. You want a city where your journey is quicker, more connected and more reliable.
The traffic filter trial is just one of the ways we’re making it happen.
By further reducing the amount of car traffic, we can improve public transport options and provide more travel connections locally, giving you more choice about how and when you choose to use them.
It’s simple. Continuing to reduce congestion helps create a healthier, more accessible and attractive Oxford – opening the door to new businesses and jobs, and increased opportunities across the county.
It’s part of the Oxford we’re building. And a change that will make a difference to all our lives.
What’s the difference between the congestion charge and traffic filters?
If you drive a car through a traffic filter when it is operating, you will need a valid permit. You can no longer pay £5 on the day if you do not have a permit.
Important: traffic filters apply to cars only. All other vehicles, including vans, mopeds, motorbikes, and emergency vehicles, can pass through these locations at any time.
What happens if I drive through a traffic filter when it is in use and I do not have a valid permit?
- For the first six months:
- We’ll send you a warning letter the first time it happens.
- If it happens again: You will receive a £70 fine. This is reduced to £35 if you pay within 21 days.
- After the first six months: You will not receive a warning letter. If you drive through a traffic filter while it is operating without a valid permit, you will receive a fine.
Things that stay the same
- Only cars need a permit. All other vehicles, including vans, mopeds, and motorbikes, can pass through these locations for free at any time. If your vehicle was exempt from the congestion charge, it will also be exempt from the traffic filters.
- Automatic number plate recognition (ANPR) cameras will enforce the restrictions.
- Traffic signs will show where and when traffic filters apply to cars. Advance warning signs will give you time to choose another route before you reach the filter point.
- Each traffic filter applies to one point on the road, over just a few metres. You can still use the road on either side at any time without a permit. There will be no physical barriers.
- The locations and operating times will stay the same as the congestion charge scheme.
Locations and operating times
- Marston Ferry Road and Hollow Way – Monday to Saturday at peak times: 7am - 9am and 3pm - 6pm.
- Hythe Bridge Street, St Cross Road, St Clement’s Street and Thames Street – Monday to Sunday between 7am - 7pm.
Can I get a permit?
Residents living in the Oxford or Oxfordshire permit areas can apply for permits to allow for a set number of free day passes for the traffic filters. Find out more about these permits:
Additional permits are available for some people and groups, including Blue Badge holders, unpaid carers and patients who need frequent hospital appointments in Oxford. You can find out about the different permit types on traffic filter exemptions and permits.
If you use your car for business, you may be able to apply for a permit. Permits are available for some groups, including mobile traders, community health and care workers, driving instructors, private hire and hackney carriage vehicles, funeral vehicles, and cars used to carry business goods. You can check the full criteria on our website to see if you’re eligible.

I had a congestion charge permit do I need to reapply:
Your congestion charge permit has transferred to a traffic filter permit, unless we have contacted you to say otherwise. You do not need to apply again. If you have an Oxford or Oxfordshire resident’s permit, your day passes have been reset to 100 or 25, depending on where you live.
How do I know how many day passes I have used?
To check which vehicle or vehicles are linked to your traffic filters permit, and how many passes you have:
- Sign in to your online account.
- Click the drop-down menu next to your name in the top-right corner.
- Select Permits.
- Look for ‘Oxford traffic filters permits’ on the list and click on the permit name.
- To check which vehicle or vehicles are linked to it, and how many passes you have, click on the permit.
Which vehicles are exempt?
Some vehicles do not need a permit. This is because of the type of vehicle they are, or because they are being used for essential services.
The following vehicles are exempt.
- vans
- motorbikes, mopeds and scooters
- HGVs and lorries
- coaches.
Most cars need a permit. However, some cars are exempt when they are being used for specific purposes
- Emergency services
- Military vehicles
- Highway and utility works, in certain circumstances
Not sure if your vehicle needs a permit?
Some vehicles do not need a permit because of how they are classified by the DVLA. You can check your vehicle using the DVLA vehicle checker. Look for the section called ‘vehicle type approval’.
If it says M1, the DVLA classifies your vehicle as a passenger car, which means it will need a valid permit to travel through the traffic filters.
How do I share my views about the trial?
