How do I submit an FOI request for the TMO?

Contact the council's FOI team (usually foi@[council].gov.uk or via whatdotheyknow.com). Request: 'The Traffic Management Order or Orders authorising the [restriction type] at [exact location] that were in force on [date of contravention], including any amendments.' They must respond within 20 working days.

What if the council says the information is exempt from FOI?

TMOs are public legal documents — they must be publicly available and cannot be withheld under FOI exemptions. If the council refuses to provide the TMO, that refusal is itself strong evidence of a potential defect in the TMO or its publication. Consider making a formal complaint to the Information Commissioner.

Can I raise a TMO challenge if I did not submit one initially?

You can raise the TMO challenge in your formal representations and at appeal. However, if you have already accepted a discounted charge, you may have waived your right to challenge. Always raise the challenge before making any payment.

Does the Herron case mean any minor TMO error defeats enforcement?

The court in Herron examined whether the TMO covered the specific restriction — not whether it had minor drafting errors. Substantive failures (wrong road, wrong restriction, wrong hours) are more likely to succeed than minor typographical errors. Adjudicators apply a reasonableness test.

Road Traffic Regulation Act 1984, ss.1–6 — Traffic Management Orders

By GetRighted Legal Research TeamLast updated July 2026

Summary

Road Traffic Regulation Act 1984, Sections 1–6 are the foundation of all traffic restriction enforcement. A Traffic Management Order (TMO) made under these sections is required before any traffic restriction can be lawfully enforced. The TMO must be made by the correct authority, cover the specific road and restriction, be properly advertised, and be in force on the date of the alleged contravention. R (Herron) v Parking Adjudicator [2011] EWCA Civ 905 confirmed that the TMO must specifically authorise what is being enforced. FOI requests to obtain the TMO succeed in approximately 50% of cases where a TMO defect is the primary ground.

Operative Text
A TMO must: be made by the relevant traffic authority; specify the exact roads, restrictions, and times; be properly advertised before implementation (Local Authorities' Traffic Orders (Procedure) (England and Wales) Regulations 1996); be sealed and dated. If no valid TMO exists for the restriction being enforced, the PCN is unenforceable. R (Herron) v Parking Adjudicator [2011] EWCA Civ 905: the TMO must specifically authorize the restriction being enforced — not merely a related restriction on an adjacent road or a generally similar restriction.

What This Means for Your Ticket

Before any council can issue a PCN for a traffic contravention, there must be a valid TMO in force covering that exact restriction at that exact location and time. The council must produce the TMO in appeal proceedings. If the TMO does not cover the specific restriction (e.g., covers adjacent roads but not yours; covers different hours; has been revoked), the PCN is unlawful. Submit an FOI request for the TMO before your appeal deadline.

Common TMO Failures to Investigate

FOI request for the TMO, then check:

✓Does the TMO cover the exact road name and location where the alleged contravention occurred?
✓Does the TMO specify the restriction type that was enforced (bus lane, yellow box, no right turn)?
✓Are the operational hours in the TMO the same as those shown on the signs?
✓Was the TMO in force on the date of the alleged contravention? (Check commencement date)
✓Was the TMO properly advertised before enforcement began?

Impact on Appeal Outcomes

Approximately 50% success rate overall — this is an investigation-dependent defense. Where an FOI reveals no valid TMO covering the restriction, success rates are substantially higher. The defense requires effort but can be decisive.
