Understanding Railroad Crossing Markings: What Does "RR" Mean?

When you're cruising down the road, it’s easy to overlook the details that can make a huge difference. But if you spot "RR" markings on the pavement, it’s time to pay attention! Knowing what these markings mean isn’t just trivia; it’s a vital piece of driving knowledge, especially when you’re preparing for your Colorado CDL tests.
