I will just speak to amendment 151. As was said in the conversation that we had in a previous group on national standards, it is right that we should set a national technical standard for the zones, but it is also really important that we have national signage standards.
Amendment 151 would provide in the bill that ministers will introduce regulations that will ensure that there will not be different traffic signage used in different zones. I lodged the amendment for the reason that Colin Smyth gave—I thank him for his support—which is to ensure that there is consistency across all the zones and that drivers understand the signage and know exactly when they are entering or exiting a zone, and the rules that operate around it. That consistency of message, whether at the side of the road or in road markings, would ensure that no matter which city someone was driving in, they would know exactly when they were in or out of a zone.
Anyone who has driven through London congestion charge areas will know that when the areas were introduced, there was ambiguity about which side of a street was in or out of a zone, and that was an opt-in scheme so people needed to know whether they were going to pay the fee accordingly. The difference here is that people will not know until they get the fine through the post a couple of weeks later.
This is an important, small but useful amendment that will ensure consistency across all low-emission zones as they are introduced across Scotland.
