Yellow box junction markings and yellow waiting restriction markings

Mon, 17 Mar 2025 16:19:23 GMT

This is a similar query to the one about the laying of yellow waiting restrictions through a ped crossing place marked with crossing studs.

The boundary of a yellow box may run parallel to the kerb. In this case, should yellow waiting restriction lines be discontinued where they meet the box?

Similarly, where a cut-out is formed in the box by a kerb-line should waiting restrictions also be removed from within this cut-out?

The TSM, Ch3, tells us when waiting restrictions should be discontinued through other markings but doesn't mention yellow boxes.

Also, should loading restrictions (kerb ticks) be shown adjacent to a yellow box in the circumstances described above?

Instinct, rather than knowledge, tells me that yellow lines are for controlling waiting vehicles whereas YBJ are for controlling moving vehicles and that will take precedent. Also, it has been held at the Traffic Penalty tribunals that yellow lines do not need to be continuous for the restrictions to apply - short gaps caused, for example, by road works, or reinstatements, do not affect the ability to enforce. So, in the absence of absolute guidance in TSM, I would suggest visual aesthetics to be the decider. And where a YBJ followed a kerbline it would be nonsense to apply the yellow lines, in the same way as they are not applied in a pedestrian controlled area. I'm open to persuasion with fact however, as this is a hunch having not read up in TSM. 😊

Waiting restriction lines should not be continued through (under or over) a yellow box marking. It has been held at adjudication (a number of times) that the YBJ layout as shown in TSRGD must be as shown. Any additional markings have rendered it unenforceable. See also diag 1004, 1005, 1008 lane guidance markings, which also should not be installed under/over a yellow box.
