We answer roadside calls all day. Most of them would have been a five-minute self-fix if the driver had one of the items below in the trunk. Nothing fancy, nothing overpriced, just the stuff that works.
The picks come from patterns, not sponsorships. Dead batteries and flat tires make up the majority of what dispatch handles, and both are recoverable on your own if you have the right tool and a few minutes of daylight. A portable jump starter turns a two hour wait into a two minute fix. A twelve volt inflator gets a slow leak back to a shop before it strands you. Reflective triangles are the difference between being seen and being hit. A basic kit covers the rest.
A few notes before you buy. Charge a jump pack every three to four months, because lithium packs self discharge and a dead pack is useless in an emergency. Store the inflator and the kit in the trunk rather than the cabin so they are not loose projectiles in a crash. Check the sealant expiry on tire repair kits once a year. And know the limits: none of this fixes a seized engine, a snapped belt, or a sidewall blowout. When you hit that line, call and we will get a truck to you.

Turns a dead battery into a five-minute self-fix. No second car, no waiting for a friend with cables - clamp it on, start the engine, drive away.
Reseat a slow leak or top off a soft tire on the side of the road so you can get to a shop safely instead of waiting for a truck.
Fix a nail or screw in the tread yourself, in about ten minutes, without dismounting the tire.
Keeps you visible if you're stuck on the shoulder or in a lane. This is the single cheapest thing that meaningfully lowers your risk of getting hit.
One bag that covers the small emergencies - dead battery, minor injuries, low visibility, a stuck tire in snow. Toss it in the trunk and forget about it.
