CRITTENDEN, Ky. Law enforcement agencies in Kentucky have received a federal grant to crack down on speeding and aggressive driving on Interstate 75/71 in northern Kentucky.

The $1 million federal Motor Carrier Safety Assistance Program grant also will be used to address problems on portions of Interstate 65 between Louisville and Lebanon Junction, Ky.

The Department of Kentucky Vehicle Enforcement considers the two stretches of interstate to be the most dangerous sections of highway in the state.

"We want to use the grant to address aggressive driving behavior on I-75 as well as increase proper driving behavior," said a spokesman for the vehicle enforcement department. "In the end, obviously, our goal is to reduce the rate of serious injury and fatal collisions."

The effort will include a number of organizations that regularly patrol the stretch of I-75/71, including the Kentucky State Police and the Boone County Sheriff's Department.

The stretch of I-75 known as the Cut-in-the-Hill - from Covington to Fort Wright, Ky. - has been particularly dangerous. Law officers say the major problem has been speeding.

Last year, the state installed signs over the northbound lanes warning of the steep grade. That was followed in January with yellow warning lights that were positioned at the top of the hill in an effort to slow traffic.

The state also announced plans this year to place solar-powered speed monitoring signs along the stretch of road in hopes drivers would heed the message and slow down.

And in March, the Kentucky State police assigned a trooper to patrol the interstate between I-275 and the Ohio River. That was the first time the state police has had such a detail in more than 10 years.

The crackdown on excessive speeding, improper lane changing, reckless driving and driving too close to another vehicle is expected to start this month.
