3.7.3.11 Desirable Minimum sight distances in accordance with Table 3.7.3.2 should normally be
available to motorists on the approach to a zebra crossing, and should only in exceptional
circumstances be less than the Absolute Minimum. Appropriate warning signs should be
erected where visibility distances, are at or below Absolute Minimum.

3.7.3.12 The location of zebra crossing as with other crossings should take account of advice given in
section 3.7.1. However particular care should be taken where zebra crossings are located
near bus stops that stopped buses will not obscure the vision of pedestrians or motorists.
Zebra crossings should also be avoided near points where traffic streams merge as the
motorists will have difficulty in observing both the traffic to be merged with, and possible
pedestrians on the zebra crossing ahead. At exits From roundabouts particular problems
arise where if the crossing is sited too close to the roundabout vehicles may tail back onto
the roundabout, but if it is located too far away pedestrians may not use it. Each situation
will require individual consideration but generally the crossing should not be located closer
than 20m to the roundabout exit.
3.7.3.13 Zebra crossings impose a number of restrictions on vehicles, which are mentioned in more
detail in Volume 3, and it is important that the implications of these restrictions are taken
into account when proposing the installation of any zebra crossings. A particular point to
bear in mind is the stopping restrictions imposed by the Zebra Controlled area and what if
any implications this may have on frontage developments.
