(1) A road hump constructed or maintained in a road shall be so constructed and maintained that—
(a) save as provided in paragraph (3) below, it extends across the whole width of the carriageway on which it is placed and its cross-section conforms to the pattern, the length measurement and either of the height measurements as shown in the Schedule, a measurement being deemed to conform if it is, in the case of a vertical measurement, no more than 15 per cent or 12 millimetres greater or no more than 20 per cent or 12 millimetres less, and, in the case of a horizontal measurement, no more than 5 per cent, greater or less, than the corresponding meas urement so shown;
(b) no part of it is within 8 metres of a road junction giving access to vehicular traffic to that road or a horizontal bend with an inner kerb radius of less than 50 metres at which a vehicle would change its direction by more than 45 degrees;
(c) it is at right angles to an imaginary line along the centre of the carriageway of the road in which it is constructed;
(d) it is not within 500 metres of another road hump in that road unless it forms part of a series with that other road hump; and
(e) 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 the distance between road humps on the gradient is not greater than 70 metres.
(2) A road hump may be constructed and maintained so that its centre line, at right angles to the edge of the road, is in the same position as the centre line of the pattern of black and white stripes specified in paragraph 4(1) of Schedule 2 of the “Zebra” Pedestrian Crossings Regulations 1971.

(b) within 20 metres of any part of any traffic sign of a kind shown in diagram 845, 846, 847, 848, 849, 850, 851 or 852 in Part IV of Schedule 1 to the Traffic Signs Regulations or within 10 metres of a traffic sign of a kind shown in diagram 1025, 1025.1, 1025.2 or 1025.3 in Schedule 2 to those Regulations;
(c) under or within 25 metres of a structure over a carriageway of the road any part of which is 6.5 metres or less above the surface of the carriagway;
(d) where it would form part of a series of more than 20 humps; or
(e) above or within 25 metres of any part of a bridge, tunnel, culvert or other similar structure over or through which that road passes.
