In Minnesota, we created an interesting law. If you are under the speed limit, get in the right lane. As long as you’re at at least thespeed limit you can be in the left lane or if you are passing, you can be in the left lane. Would create a bit of a problem if you’re doing the speed limit everybody else trying to go faster. Most people will move over if they there’s traffic coming up behind them. But not everybody. Then again here in Minnesota we don’t care we pass on the left , we pass on the right where ever is available.
