There are only two
types used:
- double lines usually to mark lengths of road where
there is no waiting at any time. However there are exceptions to
this and supplementary plates fixed to lighting columns or posts
will tell you what the actual restriction is.
- single lines usually indicate a shorter period of
restriction such as daytime. Again supplementary plates will show
the actual times.
Loading restrictions are
shown by yellow markings on the kerb and on the supplementary
plates.
White lines on the road are
provided to help road users by giving different types of
information on lane use and directions.
Road markings are as
important as signs. Longitudinal markings inform and warn road
users of approaching situations that will require them to take some
form of action (ie. solid white line - do not cross, or lane line -
turn right).
Transverse lines also give
instruction (ie. stop or give way).
The
Highway Code gives
examples of the lines in normal use and their associated rules.
All lines on the highway
must be authorised by the Authority. Special lines are allowed with
prior approval of the Department for Transport, or if they are
experimental and under trial.
