There is a wide range of parking controls that a local authority can provide near schools. The Traffic Signs Regulations and General Directions (TSRGD) 2002 gives local authorities powers to implement yellow zig-zag and keep clear road markings. These markings indicate where vehicles should not stop outside a school entrance. The local authority can determine whether the markings are advisory or made mandatory with an appropriate traffic regulation order. There are no plans to change these controls.
