JEFFERSON CITY - The Missouri Department of Transportation released a new study saying J-turn intersections have significantly reduced automobile crashes at five intersections.

The University of Missouri study found the number of crashes at the J-turn sites were down 35%, with the number is disabling injuries dropping 86%. There were no traffic deaths at the intersections studied since the turns were installed.

"The numbers speak for themselves," said David Silvester, Central District Engineer for the Missouri Department of Transportation.

J-turns are an alternative to traditional intersections on four-lane highways.

The chief researcher said the report shows the J-turns work.

"The elimination of fatal crashes and a significant reduction in disabling injury crashes are substantial safety improvements offered by the J-turn design," said Praveen Edara, associate professor of the university's Department of Civil Engineering.

A summer survey conducted by the university and MoDot found mixed public reaction to the J-turns.

A news release from MoDot said the most common complaints were: merging difficulty after the U-turn, insufficient U-turn radius to accommodate large vehicles, general driver uncertainty and improper use of acceleration and deceleration lanes.

MoDOT will work on increasing driver education about the turns.
Silvester said, "We will continue to promote the safety benefits derived from using J-turns and work to inform drivers on how to properly navigate them."
