Driving an RV or hauling a trailer when you are tired is dangerous. It just doesn’t make sense to keep going when your brain and body need to sleep.
Highway engineers knew this when they put many rest areas on most of the major routes throughout the US and Canada. These rest stops are usually set up with a parking area, restrooms, and a few picnic tables. Really awesome rest stops have some nice trails or walkways to stretch legs and refresh. There are even a few rest areas with Wi-Fi access and/or a small store where you can buy souvenirs and refreshments. These days, it’s not unusual to find rest stops with electric vehicle charging stations.
Rest areas are plentiful along most highways because driving is hard work, and sooner or later we can all benefit from a visit to the restroom, a stretch of our legs, and maybe even a nap. If the sun is setting, it can be tempting to just park for the night.
