Light & visibility
A breakdown at night on a roadside is a visibility problem before it's anything else — being seen keeps you from being hit.
- Reflective triangle or road flares
- Reflective safety vest — wear before exiting
- Headlamp, hands-free
- Flashlight + extra batteries
- Glow sticks, 2–3
First aid
Vehicle injuries are common enough that a dedicated kit here, separate from your go-bag's, is worth the trunk space.
- Small first aid kit
- Burn cream or gel
Food & water
Being stuck for hours is more common than a crash — food and water make that wait manageable, not miserable.
- Bottled water, replace regularly
Shelter & comfort
A car can become your shelter faster than you'd expect — a breakdown in bad weather is still an exposure risk.
- Poncho or plastic sheeting
Communications
A dead phone turns a minor breakdown into a real emergency — redundant power and written info close that gap.
- Car phone charger
- Portable power bank, kept charged
- Written emergency contact card
Tools & safety
Most roadside problems are fixable in 15 minutes with the right tool — the ones that aren't are exactly when you need the fire extinguisher.
- Jumper cables or jump starter
- Tire pressure gauge
- Spare tire, verified aired up
- Lug wrench + jack, matched to vehicle
- Duct tape or multi-use tape
- Multi-tool or basic tool kit
- Ice scraper (seasonal)
- Small fire extinguisher, auto-rated
Documents — waterproof folder
In a real roadside emergency, you don't want to be searching your phone for insurance info while stressed.
- Emergency instructions card
- Roadside assistance contact info
Seasonal swap
❄️ WinterIce scraper, cold-rated blanket or sleeping bag, sand or kitty litter for traction, hand warmers. Never let the tank drop below half — fuel line freeze risk.
☀️ SummerExtra water (heat means faster dehydration), sunshade, check tire pressure more often — heat expands air.
Road-trip vs. daily-commute
Daily commute — minimalistFirst aid, phone charger, flashlight, water, energy bar, small tool kit. Fits in a glovebox or trunk corner.

- Flashlight
- Jumper cables or jump starter
- Basic multi-tool
- $20 cash, small bills
- Written parent/emergency contact card
- Tire pressure gauge
