It’s a good idea to keep an emergency roadside kit in case you do get stuck. Keep a spare cell phone charger, a flashlight with extra batteries, a first-aid kit, water, snacks, battery jumper cables, emergency flares, and reflectors. You’ll never know what will come in handy if you’re stuck on the side of the road. A can of “fix-a-flat” could also get you off the highway and safely to a gas station or maintenance shop. General tools including screwdriver and crescent wrench are helpful as well.
