Airplanes will be used to spot speeders this weekend on busy highways in Jackson and Buffalo counties.
Aerial traffic enforcement will be used Saturday on Interstate 94 in Jackson County and Sunday on Highway 35 in Buffalo County, according to a State Patrol news release.
Pilots use highway marking and a timing device to identify vehicles that are speeding, and then relay the information to patrol vehicles on the ground that will stop the offending drivers.
The State Patrol chooses highway corridors for aerial enforcement using data on traffic citations, crash statistics and other information tied to traffic safety. Federal funds pay for most aerial missions, the State Patrol news release stated.
