DCAN 15: Vehicular Access Standards
Visibility on the Priority Road

3.1 Forward visibility as shown in Figure 3 is also required to provide intervisibility between vehicles using the minor road and those proceeding along the priority road. In particular, a vehicle waiting on the priority road to turn right into the access must be able to see oncoming traffic and be seen by following traffic. Forward visibility depends on the same factors as y-distance and the normal requirements are set out in Table B and the notes thereto.
