A road trip, in some cases spelled road trip, is usually long-distance travel by car. Most often, road trips are lengthy, long-distance travel made by private vehicle. They may take days, weeks, or even months to complete, depending on how much traveling you do and where you go. A road trip can also be defined as a cross-country drive, a drive that starts or ends at a certain point and is traveled upon in a straight line. Although it sounds simple enough, many people have trouble defining what a road trip actually is or what it entails.
