For drivers:

Zone entry signs: The basic premise of a CPZ has

always been that the use of entry signs displaying the periods of control obviates the need for time plates with yellow lines within the zone.

Zone entry signs: For drivers who are unfamiliar with

the area, and concentrating on other aspects of the driving task, it can no longer be assumed that entry signs alone are adequate to provide information about the zonal yellow line restriction.

Zone entry signs: Some authorities give the same zone

name to adjoining zones with different yellow line restrictions, because the same permits are valid in each.

Even though CPZs have been around for 40 years, drivers don’t really know what they are - unless they themselves live in one, or have been issued with a PCN or fixed penalty ticket for contravening a zonal yellow line restriction.

It seems unlikely that strangers visiting a CPZ would understand that zone entry signs show the times of yellow line operation, or be able to assimilate and remember the periods of control.

Since TSRGD 1994 introduced a revised yellow line system, single yellow lines mean any restriction short of a 24/7 prohibition of waiting for at least 4 consecutive months.

Drivers entering a CPZ only have entry signs to tell them what a single yellow line means. If they miss the entry sign they don’t even know where to look for information about the restrictions, let alone what the restrictions are...

Some zones around football grounds etc now have additional restrictions on match/ event days. The events occur irregularly and event days have to be indicated on additional signs.

The statutory definition of a CPZ means that controls - waiting restrictions and permitted parking - have to be marked out in every street.

'controlled parking zone' means an area in which, except where parking places have been provided, every road has been marked with one or more of the road markings shown in diagrams 1017, 1018.1, 1019 and 1020.1;

Even in wider streets, the provision of signs and lines may result in unacceptable clutter where there are many driveways interrupting parking spaces. The treatment of dropped kerbs - to mark with a yellow line or not - is an issue.
