(Distances in metres unless stated otherwise, numbers are minimum numbers)
Notes
The maximum spacing between cones in longitudinal lengths shall be 9 metres, but no fewer than two cones shall be used in any length between tapers.
Lead-in tapers where two-way traffic control is used, and all exit tapers shall be at about 45º to the kerb line with cones spaced 1.2 metres apart maximum.
In certain circumstances on congested roads with speed limits of 30 mph or less, the lead-in taper may be reduced to 45º (see page 19).
The longways clearance (L) is the distance between the end of the lead-in taper and the first traffic barrier placed across the lane.
