DOUBLE WHITE LINES
prohibitory line is an endorsable offence and is subject to the "totting-up" procedure (section 36 of the Road Traffic Act 1988) the appropriate Commissioner of Police or Chief Constable should always be consulted whenever it is proposed to install new double line markings.
5.8 Double lines should not normally be used in built-up areas, as preventing vehicles from stopping could be unduly restrictive. They might, however, be required at certain difficult positions, on three-lane hills (see para 5.27 to 5.35) or at level crossings (see paras 19.13 to 19.17).
