OKLAHOMA CITY (AP) — Law officers in six states will be joining in a regional speed enforcement campaign intended to catch speeding drivers.

The Regional Speed Enforcement Campaign will be Sept. 23-25 in Oklahoma, Arkansas, Kansas, Iowa, Missouri and Nebraska.

The Oklahoma Highway Patrol says officers will be concentrating on high traffic roadways in the effort to reduce speeding-related auto crashes.

Authorities say 27 percent of crash fatalities nationwide in 2015 were related to speeding of driving too fast for conditions and that 86 percent of all speeding-related traffic fatalities were on roads where the posted speed limits were 55 miles per hour or lower.
