Common Questions
Q: If we put up a reduced speed limit sign won't that slow traffic down?
A: No. Signs are one of many factors motorists take into account when determining an appropriate safe speed. Before and after studies in many Montana communities, and across the country, show that simply lowering the speed limit does not change driver behavior.Q:Will raising the speed limit cause motorists to speed up?
A: No. Raising the speed limit with the consent of local officials simply aligns the speed limit with actual traffic operation during favorable roadway conditions.
Q: Don't local officials have any input on what speed limit(s) are set?
A: Yes. Your local officials are instrumental in having a study conducted and provide valuable insight about the public's view on the speed limit.
