Whether you're traveling across town or cross-country, it's always good to have some basic supplies to deal with roadside emergencies. If you don't already have them, the Accutire Excursion Road Kit is an excellent all-in-one solution.
It features an emergency warning triangle, jumper cables, air compressor, first aid supplies, gloves, duct tape, cable ties, hand-charged flashlights (no need to worry about a dead battery if it sat unused for years) and basic hand tools. View a complete list of what the kit includes here.
A basic set of tools like this can be a big help if you encounter any mishap on the road. Trim or bodywork coming loose? Duct tape and zip ties may hold it in place until you get somewhere for a proper repair and prevent further damage.
What happens if you come out to your car and find a flat tire? If the leak is slow, the compressor can pump it up enough to allow you to limp to a service station.
If your car battery is dead after a roadside stop, your hazard lights may not work. The kit's warning triangle lets other motorists know you're stranded, and the jumper cables will allow you to get a jump start.
This kit is an excellent set of basic supplies. There are a couple of things that I would consider adding: a tire plug kit to permit short-term repair of a punctured tire before re-inflating and a compact mylar blanket that provides a lot of insulation in a pinch.
