Overtaking Zone
There may be stretches of road where the safe overtaking distance can not be provided. In such cases, overtaking opportunities for vehicles moving at a design speed should be given at frequent intervals. These zones which are meant for overtaking, are called overtaking zones. Â
The minimum length of overtaking zone should be three times the safe overtaking distance i.e., 3(d1+d2) for one-way traffic & 3(d1+d2+d3)for two-way traffic.
[O.S.D = Overtaking Sight Distance ]
O.S.D =(d1+d2) for one way traffic=(d1+d2+d3) for two way traffic.
SP1 = Sign Post ” Overtaking zone ahead”
SP2 = Sign Post “End of Overtaking zone”
