Texas "Move Over" Law

Ok, you see a cop ruining someone's day by stopping him on the shoulder. You are hauling butt down the highway. Any obligations? The law passed a couple of years ago states a driver must either (1) vacate the lane closest to the stopped emergency vehicle if the road has multiple lanes traveling in the same direction or (2) reduce his speed to 20 miles per hour below the speed limit. Texas Transportation Code 545.157
