 100 m, 1 km and 2 km after the start of the pattern. These distances may be regarded as approximate so that advantage may be taken of any existing safety fences. A sign to diagram 2934 "Check your distance" must be provided, and placed about 300 m before the commencement of the markings, with the variant "Keep your distance" about 300 m after they terminate. These should normally have an x-height of 250 mm on dual two-lane motorways and 300 mm on dual three or four-lane motorways.

FORMATION OF WORDS

22.45 The basic characters for worded road markings are the capital letters, numerals, apostrophe and the ampersand from the Transport Medium alphabet, enlarged and where appropriate elongated to two standard sizes. The alphabets are shown in Part VI of Schedule 13 to the Regulations.

22.46 To ensure correct letter spacing when forming a word, the characters are placed on imaginary tiles which vary in width according to the size of the character and the tiles butted up to each other to make the legend. The tile width for each letter is shown in table 22-2. The distance between the tiles of separate words (e.g. NO ENTRY when marked on a single line) is 400 mm, measured to the edge of the tiles and not to the actual characters.

NOTE: Diagrams 1058 and 1058.1 are prescribed in special sizes and may be used only for cycle facilities.
