As we learned earlier, the larger the road, the higher the speed limit tends to be. This concept is also applied to road surfaces. Roads made out of concrete or asphalt will not only have higher speeds, they will also have the right of way over gravel or dirt roads. So, another factor that determines right of way is the road's surface. The rougher, more narrow road will yield to the bigger, smoother road. The road's surface determines speed on that road as well. The smoother the road, the higher the speed will be. The rougher the road the slower the speed will be. This road surface issue also reflects the concept that the slower moving vehicle will be able to slow down or yield easier than the faster moving vehicle on the paved road. Therefore, the size of the road, the speed of the road, and the surface of the road all work together to determine who has the right of way.
