London Tribunals case commentary

Not noticing a lawful no-left-turn sign did not establish a ground of appeal (2026)

Case 2250463125 · 30 December 2025 · Adjudicator Laura Marshall

Wentworth Street, Commercial Street to Osborn Street

“I accept the evidence of the Enforcement Authority and find the signage to be lawful and adequate.”

Laura Marshall, adjudicator's reasons, case 2250463125

The driver accepted making a left turn against a no-left-turn sign, explaining that they had not focused on the sign and had caused no obstruction. They asked for cancellation as a goodwill gesture.

Tower Hamlets provided the relevant Traffic Management Order, footage and still images of the movement, and photographs showing the sign in place. Laura Marshall accepted that evidence, found the signing lawful and adequate, and concluded that the contravention occurred and the PCN was properly issued.

The adjudicator refused the appeal. The decision distinguishes a defect in the restriction or evidence from an explanation of why a driver missed a sign. The absence of obstruction did not make the prohibited turn lawful.

The practical lesson is to test the evidence before appealing. Where the order covers the turn, the signs adequately communicate it and the footage proves the movement, a general request for goodwill does not disprove the allegation. Mitigation should be put to the authority as a request for discretion, not described as a signage defect.
