Authorities say there are two main reasons for the high number of collisions, inattention to what other drivers are doing and following too close to other vehicles.
Cleaver says the county went from an upposted 50 mph to a posted 45 mph speed limit over about 2.21 miles of road. If a driver is going 50 mph the travel time is 2 minutes and 39 seconds. The same distance at 45 mph will take an extra 18 seconds.
