A breakdown, flat tire or sudden storm can leave you stranded. A well-stocked car emergency kit helps you stay safe, signal for help and handle simple problems. You do not need every gadget, but a few essentials make a big difference.
This guide lists items worth considering and explains why. Adapt the list to your climate, driving habits and vehicle. Government emergency preparedness agencies publish their own recommended vehicle kit lists that are worth reviewing.
Safety and Visibility
- Reflective warning triangles or flares: Alert other drivers if you are stopped
- Reflective vest: Makes you more visible outside the car
- Flashlight with spare batteries, or rechargeable light: For night breakdowns
- Whistle: Signals for help
Power and Communication
- Jump starter or jumper cables: Portable jump starters let you start a car without another vehicle; keep them charged per manufacturer guidance
- Phone charger and cable: Keep your phone powered
- Written emergency contacts: In case your phone dies
Tire Tools
- Spare tire, jack and lug wrench: Check they are present and the spare is inflated; some cars have inflator kits instead of spares
- Tire pressure gauge: Check pressure regularly
- Portable inflator: Can top up low tires
- Tire sealant kit: Some cars include one
Learn how to use your vehicle’s tools before you need them; your owner’s manual explains.

Practicing Before You Need It
Find your jack points and spare in daylight at home, following the owner’s manual. Practice using your jump starter’s clamps and controls. Knowing your tools in calm conditions makes roadside problems easier.
A Note on Roadside Safety
If you break down, pull as far off the road as you safely can, turn on hazard lights and stay aware of traffic. In many situations it is safer to stay in the vehicle with seatbelts fastened or move well away from traffic. Call for help when needed.
Starting Small
You do not need to assemble a full kit in one day. Start with a flashlight, phone charger, first aid kit, warning triangles, water and confirmation that your spare and jack are present. Add items over time.
A Note on Electric Vehicles
Electric vehicles may not carry a spare tire and may have specific guidance for jump-starting or towing. Check your owner’s manual for EV-specific instructions and roadside assistance options.
Final Seasonal Check
- Jump starter charged
- Spare tire inflated
- First aid supplies in date

A Note on Roadside Assistance
Many insurers, automakers and clubs offer roadside assistance. Know whether you have it and keep the contact number in your phone and written in your kit.
