The objectives of this survey were to determine the extent that a left turn on a red traffic signal (LTOR) has been used across the country and to learn how effective it has been. Responses were received from 43 of the 55 cities surveyed. Of the cities responding, 22 have either had past experience with LTOR or have recently enacted an ordinance which will allow LTOR in the future. Most LTOR laws limit its use to intersections of two one-way streets. A much higher percentage of cities in the western United States have laws permitting LTOR than cities in the east.
