CAR PREPAREDNESS
What should I keep in my car?

Build in layers
Your everyday layer is small. Add a true roadside emergency layer, then a winter layer if you drive in cold or snowy conditions. A family with kids, pets, or long rural drives may need more water, snacks, blankets, or medication planning than someone who drives ten minutes through town.
Choose the list you need
Prepared does not mean carrying a hardware store
A useful vehicle kit is small enough that you will actually keep it in the car and organized enough that you can find the flashlight or warning triangle in the dark. Build around likely roadside problems and your climate. Someone driving rural winter roads has a different risk profile from someone driving short urban trips in mild weather.
Store gear where you can reach it safely
Warning gear and a flashlight should not be buried under luggage. First-aid supplies should be easy to reach. Heavy items should be secured so they do not become projectiles in a hard stop. Check the vehicle owner’s manual before storing gear around batteries, inflators, spare tires, or other service areas.
