What should a roadside kit absolutely include?

Across the reviewers we read, the non-negotiables are heavy-gauge jumper cables (or a jump pack), a reflective warning triangle and high-visibility vest, a flashlight with fresh batteries, a tow strap rated for your vehicle's weight, a basic first aid module, and a window breaker/seatbelt cutter. Air compressors and tire plug kits are strongly recommended adds, especially in regions without quick roadside assistance.
