Missouri joins five other states in a regional speed-enforcement campaign starting Friday. They’re hoping to catch speeding drivers in Missouri, Kansas, Nebraska, Iowa, Arkansas and Oklahoma.

The campaign will run Friday through Sunday.

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.
