Rule Rule 734-020-0490
Conditions of Approval


The following conditions apply when installation of a traffic signal has been approved:

(1)

A traffic signal warrant shall be met within three years after construction when a traffic signal is constructed as part of a roadway improvement project.

(2)

A traffic signal warrant shall be met within one month after the traffic signal is put into operation when a traffic signal is being constructed to accommodate additional traffic from a public or private development. If it is projected that a warrant will be met at a later time, operation of the traffic signal should be correspondingly delayed.

(3)

All approaches to a traffic signal controlled intersection must be signalized, unless a traffic engineering investigation shows that signalizing a minor public or private road is not justified.
