Regulation 5 Nature, dimensions, location and spacing of road humps
Save as provided in regulation 7, no road hump shall be constructed or maintained in a highway unless–
it complies with one of the sets of specifications in the Schedule, so, however, that a measurement shall be deemed to comply if it is
in the case of a vertical measurement no more nor less than 12 millimetres;
in the case of a horizontal measurement no more than 5 per cent greater or less
than the corresponding measurement shown in the specification;
it is at right angles to an imaginary line along the centre of the carriageway of the highway in which it is constructed; and
where it is constructed or maintained in a carriageway with a gradient of more than 10 per cent., it is not within 20 metres of the top of that part of the carriageway which has that gradient and no more than 70 metres separates any road hump on the gradient from the next one.
A road hump of a type which complies with the specifications shown in drawing No 1 or No 3 in the Schedule may be constructed and maintained in a highway so that an imaginary line along the centre of the hump from one side of the road to the other is in the same position as an imaginary line from one side of the road to the other along the centre of the pattern of black and white stripes specified in paragraph 4(1) of Part I of Schedule 2 to the “Zebra” Pedestrian Crossings Regulations 1971f1.
Save as mentioned in paragraph (2) above, no road hump shall be within the limits of a zebra controlled area as defined in regulation 3(1) of the regulations mentioned in that paragraph or within 30 metres from the imaginary line along the centre of the pattern of stripes mentioned in that paragraph.
A road hump which complies with the specifications shown in drawing No 1 or No 3 in the Schedule may be constructed and maintained in a highway so that an imaginary line along the centre of the hump from one side of the road to the other is in the same position as an imaginary line along the centre of the limits of the crossing from one side of the road to the other as shown in a diagram in Schedule 2 to the “Pelican” Pedestrian Crossings Regulations 1987f2.
Save as mentioned in paragraph (4) above, no road hump shall be within the limits of a “pelican” crossing as defined in regulation 3(1) of the regulations mentioned in that paragraph or within 30 metres of any part of any such crossing.
No road hump shall be constructed or maintained in a highway:–
on a railway level crossing or within 20 metres of the nearest rail forming part of the railway track at any such crossing, or within 2 metres of any rail running in the highway otherwise than at any such crossing;
under or within 25 metres of any part of a structure over a carriageway of the highway any part of which is 6.5 metres or less above the surface of the carriageway; or
above or within 25 metres of any part of a bridge, tunnel, culvert or other similar structure over which a carriageway of that highway passes.
