 You could get stranded in a traffic jam or have a breakdown that leaves you stuck on the side of the road. ODOT's Don Hamilton suggests you carry an emergency kit. Emergency kits should always have some extra food, some extra water, make sure you take care of your pet in case you've got a pet with you traveling too. Check your vehicle's fluids, battery, and tires to help prevent a breakdown. The TripCheck website is also a good resource, especially if you're traveling through the mountains.
