Isn't a lower speed limit always safer?
No, lower speed limits do not necessarily improve safety. The more uniform the speeds of vehicles in a traffic stream, the less chance there is for conflict and crashes. Posting speed limits lower or higher than what the majority of drivers are traveling produces 2 distinct groups of drivers: those attempting to observe the limit and those driving at what they feel is reasonable and prudent. These differences in speeds may result in increased crashes due to tailgating, improper passing, reckless driving and weaving from lane to lane.

Inappropriately established speed limits also foster disregard for other speed limits, traffic signs and signals, and contribute to driver frustration. If you have any questions, please email the Department of Engineering.
