Highway authorities have a number of options for making and signing parking restrictions and provisions. Because the choices that they make will impact largely on local people, these choices are best made at local level.
The Department for Transport publishes extensive guidance on the correct design and use of signing systems for various purposes. This guidance is primarily contained in the Traffic Signs Manual, which can either be purchased in hard copy from the Stationery Office or viewed on the department’s website at http://www.dft.gov.uk/pgr/roads/tss/tsmanual/.
Additionally, the department’s officials regularly give site-specific advice and assistance to highway authorities that are dealing with unusual or difficult situations.
