Travel Safe Zones

A Travel Safe Zone (TSZ) is any area upon or around any highway where a highway safety analysis shows the number of fatal or disabling injury crashes exceeds a "predicted safety performance level for comparable roadways", as stated in Missouri Revised Statute 304.590. MoDOT uses TSZs to improve safety of a clearly defined roadway segment. This statute establishes that fines shall be doubled for moving violations.

Maps showing TSZ locations are available upon request by calling (573) 526-4293.
