Here’s a final one that will make you feel smart: DLR can refer to Daytime Running Lights. You know those bright headlights that are always on in broad daylight? That’s DLR—an acronym invented literally to keep us safe. It’s funny how the same letters can describe something that helps you see a pothole and something that helps you hear a guitar solo.
So next time you’re driving and see a sign about DLR, don’t start humming “Panama.” It’s just your car being responsible.
