Traveling by car
North America has an extensive road system. Most of the United States is paved over, and southern Canada isn't that different, either. In North America, drivers drive on the right side of the road. In the United States, Interstate highways (freeways) are generally the fastest way to get around, but you can't see much from them; US, state, and local roads are much better for sightseeing. In Canada, there is also a relatively extensive freeway system in the southeastern part of the country. However, northwest Canada and Alaska is an unpopulated and generally roadless area; only the Alaska and Cassiar Highways lead from British Columbia into Alaska.
