Practical habits that make solo trips smoother.
Share your itinerary with someone back home and check in periodically, especially on longer road trips through less populated areas. Trust your instincts about a place or situation more than you might at home, since you don't have a travel companion to sanity-check a decision with.
Keep copies of your important documents, including your driver's license and IDP, stored separately from the originals. Solo road trips are enjoyable, but building in flexible timing rather than a rigid schedule reduces the pressure to push through fatigue.
