What should a good roadside emergency kit include?

Most well-reviewed kits include jumper cables, a reflective warning triangle or flares, a basic first aid kit, gloves, a tow strap, and a flashlight or headlamp. Higher-priced kits add a portable air compressor or tire inflator, while winter-focused kits add a snow brush, ice scraper, or folding shovel. Match the contents to your climate and the length of your typical drives.
