Essential First Aid Supplies

When assembling your Car-Specific 72-Hour Kit: What to Add and Why, a robust first aid section is non-negotiable.

Tools for Basic Vehicle Repairs

Incorporating vehicle repair tools in your Car-Specific 72-Hour Kit: What to Add and Why empowers you to tackle common mechanical issues and avoid being stranded for hours.

For food, opt for high-calorie, nutrient-dense options such as energy bars, trail mix, dehydrated meals, or freeze-dried entrees that require only hot water to prepare. Ready-to-eat canned goods with pull-tab lids, peanut butter packets, and canned tuna or chicken packets provide protein and endurance.

Personal Hygiene and Sanitation Items

Pack a roll of toilet paper or tissues, disposable bags for waste disposal, and sealable plastic bags for used items.

Feminine hygiene products and diapers, if relevant, are essential for certain travelers. Include dental care items like a travel toothbrush, toothpaste, and floss picks.

Include extra pairs of socks and undergarments, a warm hat, gloves, and a sturdy pair of closed-toe shoes or waterproof boots.

By layering appropriately and having emergency blankets on hand, your Car-Specific 72-Hour Kit: What to Add and Why becomes a versatile defense against unpredictable weather.

Signaling and Lighting Equipment

When stranded, attracting attention quickly can mean the difference between a brief delay and a prolonged emergency.

Flares—both traditional and LED types—offer bright, long-lasting signals.

A durable, waterproof flashlight with extra batteries and a headlamp provide hands-free illumination for nighttime repairs or signaling. Glow sticks serve as silent, non-flammable light sources.

Important Documents and Cash Stash

During a roadside emergency, having quick access to vital documents and funds can expedite help and reduce stress. Important documents and a small cash stash are often overlooked, yet they play a critical role in your Car-Specific 72-Hour Kit: What to Add and Why.

Include emergency contact numbers, a roadside assistance membership card, and a list of nearby hospitals or repair shops along your route.
