Contravention Code 40 — Parked in a Designated Disabled Person's Parking Place Without Displaying a Valid Disabled Badge

Last updated: March 2026

Blue badge bays provide essential access for disabled drivers and passengers. If you have received a code 40 PCN, it may be because your badge was not properly displayed or a technical issue prevented the CEO from seeing it. Here is what you need to know about defending against this contravention.

What Does Code 40 Mean?

Contravention code 40 is a higher-level contravention issued when a vehicle is parked in an on-street disabled persons' parking bay without a valid blue badge clearly displayed. The penalty is at the higher band — £70 outside London or £130 in London, reduced by 50% for early payment. Disabled bays on-street are marked with a blue badge symbol and accompanying signage specifying who may park and for how long.

Blue Badge Display Rules

To park legally in a disabled bay, you must:

• Display a valid blue badge on the dashboard, with the front of the badge (showing the photograph, expiry date, and hologram) facing upward and visible through the windscreen
• Display a parking clock disc showing the time of arrival, if the bay has a time limit (typically 3 hours on-street)
• Ensure the badge belongs to a person who is present at the start or end of the journey — the badge is issued to a person, not a vehicle
• Ensure the badge has not expired

Common Defences

Badge Was Displayed but Not Seen

If your blue badge was on the dashboard but the CEO could not see it — perhaps because of windscreen reflections, tinted windows, or the badge slipping — you can appeal by providing a copy of your valid badge with its serial number and expiry date. Many councils will cancel the PCN if you can prove a valid badge existed on the date in question. Include a photograph of the badge and any correspondence confirming your badge entitlement.

Clock Disc Not Displayed

Some disabled bays require a clock disc showing your arrival time. If you forgot to set or display the disc but held a valid blue badge, this is a technical failure rather than a substantive one. While the council can technically issue a PCN, appeals on this basis often succeed — particularly at tribunal, where adjudicators recognise that the purpose of the bay is to serve disabled people and a missing clock disc does not undermine that purpose.

Badge Expired Recently

If your badge expired very recently and you had applied for a renewal, provide evidence of the renewal application and the dates involved. Councils have discretion to cancel PCNs where a badge holder was genuinely in the process of renewing and the expiry was recent. Include your renewal application confirmation and any correspondence from the issuing authority.

Bay Not Properly Signed

Disabled bays must be signed with the appropriate sign (showing the blue badge symbol) and, if time-limited, must display the maximum stay. If the signage is missing, obscured, or non-compliant with TSRGD, the bay may not be enforceable. Photograph the signage and bay markings.

Advisory (Non-Enforceable) Bay

Some disabled bays outside residential properties are “advisory” rather than legally enforceable. Advisory bays are usually installed at the request of a resident and are not backed by a Traffic Regulation Order (TRO). If no TRO exists for the bay, it cannot be enforced and the PCN is invalid. Ask the council to provide the TRO reference for the bay in question.

What Are Your Chances of Success?

Code 40 appeals have a reasonable success rate for genuine badge holders who had a display issue. Councils and tribunals are generally sympathetic to disabled badge holders, and if you can demonstrate a valid badge existed on the date, the PCN is often cancelled. For cases where no badge existed, appeals are much harder. The advisory bay defence is particularly strong where it applies, as many residential disabled bays lack a TRO.
