I drive I-69 between Fort Wayne and Indianapolis frequently, so I can see the wisdom of the "move over" law:
EVANSVILLE - Kentucky, Indiana and Illinois have passed laws within the last decade to require drivers to move over to the left lane when police have stopped vehicles along the side of the road, but such laws have proven difficult to enforce.
Motorists who ignore so-called "move over" laws often drive just inches away from officers conducting traffic stops, the Evansville Courier & Press reported. Since 2003, at least eight Indiana State Police troopers have been injured and one was killed while making traffic stops.
It also makes sense, though it's not written into the law, to move over when someone in front of you is driving onto a limited-access highway, say from the access ramp or out of a rest stop. But sometimes it's difficult, because the left lane is clogged with cars too close to you. You have to see the activity ahead of you in enough time to slow down and maneuver into the left lane
And why does this happen? Because THERE ARE MORONS who do not understand how you are supposed to drive on the interstate. You stay in the right lane, unless you need to pass -- the left lane IS A PASSING LANE. Once you have passed, you get back into the right lane. But, I swear, on every trip I make to and from Indy, I encounter at least a dozen drivers who either don't know or don't care about this rule of the road. They cruise down the left lane, at or below the speed limt, for the whole trip, as if they're on a city's surface street, driving a few blocks to pick up a quart of milk at the supermarket. If we want to make driving safer, let's have a law about THAT.
