It’s a universal template on which every state bases its rules of the road. Road rules are not just about being nice. Right-of-way at T-intersectionsThe driver on the “through road,” the road that does not terminate at a stop, has the right-of-way. That means if you’re on a road that ends at a T, the traffic on the other road, the “through” road, has the right-of-way. That means that if driver Gloria is “camping” in the left/passing lane, driver Gloria has arrogated the entire interstate to herself.
