Abstract
Surveys were conducted to determine if there is a problem with motorists determining the direction indicated by traffic light signal arrows. Canadian optometrists were asked if their patients report this problem during a visual examination. Drivers were queried about difficulty with the arrows and under what circumstances the difficulties occurred. Traffic engineers were requested to comment on the use of traffic light arrows in their jurisdictions and whether or not they perceive a problem with visibility. The results indicate that many Canadians, and Manitobans in particular, reported difficulty with the arrows.
