Box junction fines: when you can challenge

A box junction PCN uses code 31: "Entering and stopping in a box junction when prohibited". Outside London only councils that have moving traffic enforcement powers can issue it; in London the boroughs and TfL have enforced box junctions for many years.

The rule

The Highway Code says you must not enter the box until your exit road or lane is clear. You may enter and wait when you want to turn right and are only stopped by oncoming traffic, or by other vehicles waiting to turn right. At signalled roundabouts you must not enter unless you can cross the box completely without stopping (rule 174).

Look closely at the footage

  • Was your exit clear at the moment you entered? A vehicle ahead that stopped suddenly or a pedestrian stepping out can explain a stop you could not foresee.
  • Were you turning right and held up only by oncoming traffic?
  • Are the yellow criss-cross markings complete and visible?
  • How long did you actually stop, and why?

Ask the council to let you view the recording or send stills (outside London this is a legal right, SI 2022/576 reg 3(3)).

First time at a new camera? (outside London)

Government guidance says that for 6 months after enforcement starts at each camera, councils outside London should send a warning notice rather than a PCN for a first-time moving traffic contravention. If this applies to you, say so in your representations. More on warnings.

Grounds and costs

Outside London all the statutory grounds apply, plus compelling reasons. In London the moving traffic grounds are the five listed by London Tribunals. London box junction PCNs are £160 (£80 if paid within the discount period printed on the PCN).

See code 31 and the box junction cameras listed on each council page.

Questions

I only stopped for a second. Is that still a contravention?

The contravention is entering and stopping in the box when prohibited, so any stop counts in principle. What matters is whether your exit was clear when you entered and whether the stop was caused by something you could not foresee.
