Roadside Emergency Kit – Every year, over 4 million drivers experience roadside emergencies, yet fewer than 20% have a properly stocked emergency kit in their vehicle. A well-prepared emergency kit can mean the difference between a minor inconvenience and a life-threatening situation when you’re stranded on the roadside—especially in extreme weather, remote locations, or during nighttime hours when help takes longer to arrive.
Quick Answer: A complete roadside emergency kit should include: basic tools (jumper cables, tire repair), safety items (reflective triangles, flashlight, first aid), emergency supplies (water, blankets, phone charger), and seasonal items (winter: ice scraper, blanket; summer: extra water, sunscreen). Total investment: $75-150 for comprehensive protection.
For vehicle safety standards and emergency preparedness guidelines, consult the National Highway Traffic Safety Administration (NHTSA) emergency preparedness resources.
