Most car emergencies are mild but get worse fast if you're unprepared - a flat tire becomes a 4-hour wait, a no-start becomes a tow bill, a fender bender becomes hypothermia in winter. This 18-item kit fits in a single trunk box and handles 95% of roadside scenarios.
⚠ ImportantRefresh the kit twice a year (spring and fall). Water bottles leak, batteries die, food expires, first-aid supplies get used and not replaced.

❓ Frequently Asked Questions
What's the most important thing to have in a car emergency kit?
Jumper cables or jump pack, plus a charged phone. 70% of roadside emergencies are dead-battery or low-tire issues.
How often should I check my emergency kit?
Twice a year - spring and fall. Water leaks, food expires, batteries die.
Where should I store the kit?
In the trunk in a clear plastic box. Some items (water, food) belong in the cabin in extreme cold so they don't freeze.
Are pre-built kits worth buying?
They're a fine starting point. Most need supplementing - first aid quantity is usually thin and they rarely include a jump pack.
Do I need flares or are reflective triangles enough?
Reflective LED triangles are better in almost every way - reusable, no fire risk, visible farther.
Should I keep tools beyond a multi-tool?
A basic socket set helps if you might do a tire change at night. Otherwise, multi-tool covers 90% of needs.
