How to Challenge a Code 31 PCN: Yellow Box Junctions

What a Code 31 PCN Alleges

Code 31 concerns entering and stopping in a box junction when prohibited. The legal test is not simply whether a photograph shows your vehicle over yellow paint: examine the entry and whether the vehicle had to stop in the box because of stationary vehicles. This is a moving-traffic allegation, not a parking overstay.

Challenge the Postal Moving-Traffic PCN

A moving-traffic PCN normally arrives by post with access to the camera evidence. Read the contravention description and legislation together: the code identifies the allegation, but does not by itself identify every procedural rule.

• London, under the London Local Authorities and Transport for London Act 2003: make formal representations to the issuing authority against the PCN. Do not wait for a Notice to Owner or a bus-lane Enforcement Notice.
• England outside London, under the 2022 civil-enforcement regulations: the postal PCN invites formal representations directly. Request the recording promptly and submit your representations within the applicable period even if an evidence request is still outstanding.
• Wales: use the Welsh legislation and representation instructions on the postal PCN. The English 2022 regulations should not be quoted as though they govern a Welsh notice.
• If the authority accepts the representations, it cancels the penalty. A Notice of Rejection explains how to appeal to the independent tribunal; an informal email exchange is not a substitute for that formal decision.

London Tribunals explains the 2003 Act procedure; the Traffic Penalty Tribunal explains the process outside London. A separate guide covers code 34 bus-lane notices, including London's additional Enforcement Notice stage.

Moving-Traffic Representation and Decision Deadlines

For a London 2003 Act PCN, the representation period is 28 days beginning with service of the notice. Its payment period runs from the date of the notice, and the initial discount period is 14 days from that date. These are different starting points; calculate the deadline for the action you are taking.

• England outside London: representations under the 2022 regulations must normally be made within 28 days beginning with service. An approved-device postal PCN has a 21-day discount period beginning with service. Check the notice and any express re-offer of the discount.
• The DfT's statutory guidance for England outside London requires the authority to serve its decision on qualifying representations within 56 days of receiving them. That is not a universal deadline for every email or every UK traffic scheme.
• For London moving-traffic representations, London Tribunals says the authority should normally respond within three months. Do not import the English 2022 statutory 56-day test into a 2003 Act case.
• After a Notice of Rejection, the normal tribunal appeal period is 28 days beginning with service. Keep the notice and submission confirmation so the relevant dates can be established.

Do not assume that asking for CCTV freezes a deadline or that making representations guarantees another discount offer. Use the current notice and any written confirmation from the authority. Welsh notices must be checked against their own regulations and stated dates.

Save the Entry, Stopping Point and Exit Sequence

• Full council CCTV, beginning before the vehicle entered the box.
• Timestamped stills locating the vehicle and the traffic that allegedly caused the stop.
• Dashcam footage showing the intended turn and any unexpected movement by another vehicle.
• Wide photographs or a measured plan if the actual box boundary or location is disputed.

There is no universal five-second or ten-second exemption. A green light does not remove the box restriction, and saying that no junction was obstructed does not by itself answer the statutory test. A short stop or an unexpected manoeuvre needs to be explained in its actual context.

What the Box-Junction Recording Must Establish

• The vehicle did not stop in the box. Use the continuous recording to distinguish slow movement from a stationary vehicle and identify the box boundary.
• The alleged stop was not caused by stationary vehicles. Explain the actual cause with timestamps and supporting footage; do not describe the cause differently from what the recording shows.
• The defined right-turn exception applied. Show that the vehicle entered to turn right and was prevented from completing that turn by oncoming traffic or other vehicles waiting to turn right.
• The recording or location does not support the allegation. Request the entry sequence if it is missing and identify why the missing part matters. If the marking's lawful placement or extent is disputed, use a plan and the applicable signing requirements.

The right-turn exception does not give a general allowance to wait behind stationary traffic after turning right. Nor does it apply to every left turn. Highway Code rule 174 also gives a separate warning for signalled roundabouts: do not enter unless you can cross completely without stopping.

What to Include in a Code 31 Representation

Set out a short timeline: entry, any stop, cause of that stop and departure. State which element of the allegation is not established or why the right-turn exception applies. Refer to the actual footage rather than copying an argument about a different junction.

Send the Representations to the Issuing Authority

Use the representation portal or postal address printed on the PCN. Include the reference, vehicle registration, your explanation and the evidence supporting the particular ground. Save the completed text, attachments and dated acknowledgement; a request to view footage is not necessarily registered as representations.

The notice is normally addressed to the person pursued as owner. If you were not the owner at the relevant time, or the vehicle was hired under an agreement that permits liability to be transferred, use the corresponding statutory ground and supporting documents. Simply identifying another driver does not automatically transfer a council PCN.

Appeal a Moving-Traffic Notice of Rejection

Read the authority's reasons alongside the footage and your representations. An appeal goes to London Tribunals for the London scheme, or the Traffic Penalty Tribunal for the relevant English or Welsh scheme. Address the disputed movement, restriction or exemption rather than submitting a different generic appeal.

An allowed appeal cancels the penalty. If it is refused, follow the decision's payment instructions. Ignoring a rejection or decision can lead to a Charge Certificate increasing the penalty by 50%, followed by debt registration and an Order for Recovery. An Order for Recovery has specific procedural remedies; it is not simply another opportunity to repeat the original traffic argument.
