I was always told that the highway patrol was required to have their headlights on while sitting in the median trying to catch speeders. For about the last month now, I've noticed many a dark car with the radar gun hanging out the window on my late night/early morning drives home from work. It's also not just the OSHP, I've seen patrol officers doing this in several cities lately as well. Before the last month, I can't really recall having seen police cars trying to catch speeders without their headlights on. Has something in the law changed that they are now allowed to do this? Has it always been this way, and I was ignorant about it? Someone help me on this, I'm perplexed.
