Sutton Code 50 PCN Appeal (2026)

1. What does Sutton Code 50 mean?

Code 50 means performing a prohibited turn. The authority alleges that your vehicle made a turning movement which was banned at that location: 50L identifies a prohibited left turn, 50R a prohibited right turn and 50U a prohibited U-turn. Read the full description on the PCN, not just the number.

The important question is not simply whether your vehicle turned. It is whether the movement shown in the evidence was the movement prohibited by the restriction. Turning into a nearby driveway, turning around inside a side road and turning at the named junction are not automatically the same manoeuvre.

A green traffic light does not override a prohibited-turn sign. Following a satnav, completing the turn safely or finding the road empty does not, by itself, answer the allegation.

2. What must Sutton establish?

For a Code 50 PCN, the restriction, its signing and the evidence of your turn need to fit together. A sign photographed somewhere near the junction is not the whole case.

Match the sign to the turn alleged on your PCN. The prescribed circular signs show a black turning arrow crossed by a red diagonal bar: diagram 613 for no left turn, diagram 612 for no right turn and diagram 614 for no U-turns. Read any permitted supplementary plate with the sign: it can identify the operating times, an exception or, for a U-turn restriction, the length of road covered.

An ahead-only arrow is a different instruction. Do not substitute an ahead-only allegation for the prohibited turn on your notice, or assume that every nearby directional arrow proves the restriction being enforced.

• A restriction covering this turn: Ask for the Traffic Management Order (TMO), also called a Traffic Regulation Order (TRO), where the turn ban is imposed by an order. Check the operative article, road schedule, amendments, commencement date, direction of travel, hours and exceptions. The wording must cover the movement and location alleged, not a different junction or a different approach. TSRGD Schedule 3, Part 5, direction 1 links these signs to an underlying prohibition or restriction imposed by a statutory provision, order or another listed legal instrument. A TMO is the usual starting point, but the authority should identify the actual legal instrument it relies upon. A missing copy in an initial reply does not itself prove that no restriction exists.
• Signs that adequately communicate that restriction: For an order governed by the 1996 Traffic Orders Procedure Regulations, regulation 18 requires the authority to place and maintain signs giving road users adequate information about its effect. Compare the actual signing with the order: the prohibited direction, operating hours and any exception must tell a consistent story. The Traffic Signs Manual explains placement. For an unsignalised left- or right-turn restriction, Chapter 3 paragraph 4.5.3 places the sign immediately before the junction, normally on the left. Paragraph 4.2.9 explains the use of a prohibited-turn sign at an unsignalised T-junction. A second sign or advance warning can be appropriate to the layout; there is not a blanket rule that every Code 50 junction must have two signs. For no U-turns, Chapter 3 paragraphs 4.11.1-4.11.3 distinguish a junction, a gap in a central reservation and a restriction extending along a road. The guidance on placement, distance plates and repeat signing differs accordingly. Signal-controlled junctions require the signal-specific arrangements to be checked too. The Manual is guidance; distinguish its recommendations from mandatory TSRGD directions.
• Visibility from the driver's approach, including at night: Photograph what could be seen before the turn, from the lane and direction used. Include foliage, scaffolding, parked vehicles, the angle of the sign and any competing information. A close-up showing a readable sign does not necessarily establish that an approaching driver could read it in time. Lighting is conditional. For the relevant Schedule 3 signs, Part 4 paragraph 4 contains a direct-illumination requirement where the road's speed limit is above 20 mph and the sign is within 50 metres of a street-lighting lamp, subject to the stated exceptions and operating conditions. Check those facts before alleging a lighting defect. There is no universal rule that every turn sign needs its own lamp. Road arrows may reinforce the message. Their absence is not automatically a defence to a prohibited turn: identify any marking actually required for the installation rather than importing yellow-line or parking-bay rules.
• Evidence of the prohibited movement and a properly issued notice: Check the vehicle registration, junction, direction of movement, date and time against the allegation. The footage or other evidence must establish the turn relied upon. Ask for the continuous recording where still images leave the approach or completed manoeuvre unclear. The authority must also use the applicable enforcement power and serve a notice meeting its statutory requirements. London moving-traffic PCNs under the 2003 Act and notices issued under the English or Welsh civil-enforcement regulations do not share every procedural rule.

3. Grounds and exemptions for a Sutton Code 50 appeal

Connect each argument to a ground available under the legislation on your PCN. For a disputed turn or inadequate signing, the central ground is usually that the alleged contravention did not occur.

There is no general exemption allowing a prohibited turn simply because a driver lives nearby, holds a Blue Badge, is delivering goods or was following navigation instructions. Read the exception for this turn, not a permission relating only to entry into the surrounding area.

Where the circumstances are mitigation rather than a legal exemption, explain them to the authority and ask it to exercise discretion. Do not present a request for sympathy as proof that the contravention did not occur.

• Wrong manoeuvre or location: the evidence does not show the prohibited turn alleged, or shows a different access point outside the restriction.
• Inadequate signs: the restriction was not adequately conveyed on your approach. Identify the particular obstruction, position or inconsistency and support it with photographs.
• Restriction not operating: the recorded time falls outside the turn ban, or the order did not cover that direction or was not in force on the relevant date.
• Applicable exception: the vehicle or use fell within an exception in the governing instrument. Identify the exact provision and supporting record.
• Owner or hire liability: you were not the liable owner at the material time, the vehicle was used without consent, or the statutory hire provisions apply. Use documents that address liability, not merely the identity of another driver.
• Penalty or procedural defect: explain the specific statutory failure. Procedural impropriety is an express ground under the English 2022 scheme; it is not a separately listed ground under the London 2003 Act. Frame a London argument under its applicable grounds rather than copying a parking template.
• A signed vehicle exception, such as qualifying buses, taxis or cycles: check the order's definition and whether your vehicle or journey qualifies.
• An express access or authorised-vehicle exception: establish that it applies to the turn itself, and supply the relevant authorisation.
• Emergency use or an authorised traffic direction: identify the applicable legal provision and evidence of what actually happened. For London 2003 Act enforcement, section 4(12) addresses use for fire brigade, ambulance or police purposes; it is not a general exemption for any urgent journey.

4. How to make a formal representation to Sutton

Send formal representations to Sutton within 28 days beginning with service of the Code 50 PCN. Explain the ground relied upon and attach the evidence supporting it.

The initial 50% discount applies during the first 14 days beginning with the date of the PCN. A challenge does not automatically extend that period. Check the council's policy and any renewed offer in its reply.

1. Open Sutton's PCN service below. Enter the PCN reference and vehicle registration to find the notice and evidence.
2. Have the PCN number and vehicle registration ready. Sutton asks motorists to allow 24 hours after issue for the notice and photographic evidence to appear in its online system.
3. Sutton asks the registered keeper to make the appeal. If using a representative, the keeper must first notify the council by email or letter that the representative has been appointed.
4. Use the council-linked appeal route appropriate to the notice. For the postal alternative, send a signed and dated letter to Sutton Parking Services.
5. Moving-traffic PCNs have no informal appeal stage; use the formal representation route.
6. Explain which part of the Code 50 allegation you dispute. Include the PCN reference, vehicle registration, your address and copies of photographs or records supporting each point.
7. Postal alternative: Sutton Parking Services, Civic Offices, St Nicholas Way, Sutton, SM1 1EA. Allow time for receipt before the deadline and retain proof of posting.
8. Save the full submission, attachments and dated acknowledgement.

5. How long does Sutton have to respond?

London Tribunals says the authority "should normally respond to representations within 3 months". Keep Sutton's acknowledgement and the date your representations were received.

6. If Sutton rejects your representation

A formal Notice of Rejection explains Sutton's decision and how to appeal to London Tribunals. You have 28 days beginning with service of that notice to pay or register your tribunal appeal.

Compare the reply with the Code 50 grounds and evidence you submitted. Identify any unanswered point, missing evidence or inconsistency between the restriction and the recorded event. Keep the rejection notice and the appeal details supplied with it.

7. Taking your Sutton appeal to London Tribunals

London Tribunals is independent of Sutton. Use the registration instructions and verification details in the Notice of Rejection, upload your evidence and explain why the alleged Code 50 contravention or liability is disputed.

There is no fee to register the appeal. If it is refused, the full penalty is normally payable; an earlier discount does not automatically continue. If registering late, explain the delay so the adjudicator can decide whether to accept the appeal.

Read Sutton's evidence pack and respond to the points relevant to your case. Keep to the tribunal's directions and evidence deadlines.
