GARY, Ind. -- Indiana State Police have a new tool to determine whether drivers are tailgating and should get a ticket.
Laser speed guns used by troopers can capture the time elapsed between the back bumper of one vehicle and the front bumper of the one behind it. The guns also take an accurate image of the license plate and driver's face.
The Post-Tribune reports (http://bit.ly/S0d8SX ) the devices are worth about $5,500 each and are only being used on the Borman Expressway right now.
Sgt. Ann Wojas says every Indiana State Police district will eventually receive at least one of the guns.
Troopers say the guns remove guesswork and provide evidence that's hard to fight.
The fine for following too closely is around $140, which includes court costs.
