1Installation and site selection#

The approach to informal ‘3-2-1 green reflector’ stopping places are denoted by a series of green reflectors placed on existing road edge guide posts.

It is important to consider the speed environment and the maximum vehicle size allowable on each particular road segment. As a minimum, however, it is recommended that the first series of three reflectors is a minimum of 500 m before the site itself in order to allow a safer stopping distance.

The system of marking sites begins with:

  • three green reflectors mounted on a guide post at a minimum of 500 metres
  • two green reflectors at a minimum of 250 metres
  • one green reflector on the guide post immediately before the stopping place.
