A roadside problem is easier to handle when the essentials are already in your car. We build a practical kit around three priorities: staying visible, handling simple vehicle issues, and getting help when a repair would put you at risk. The best kit is one you can find quickly, use confidently, and keep ready for the trips you actually take.
Pack a reflective warning triangle or another visibility aid, a reflective vest, and a flashlight with working batteries. Keep a charged phone and a backup power bank available, too. These items help you see what is happening, make yourself more visible, and call for assistance without immediately reaching for a tool.
If your car can be moved, pull into a safe location away from traffic before assessing the problem, and turn on your hazard lights. If you cannot reach a safe location, prioritize calling roadside assistance or emergency services rather than working on the vehicle. Never set out a warning triangle or attempt a repair if doing so would put you near moving traffic.
Add a small first-aid kit and personal supplies you might need while waiting. Water and weather-appropriate clothing matter more on long drives or routes with limited services. For a broader approach to emergency supplies, see Ready.gov’s kit guidance.
| Need | Items to consider | When they help |
|---|---|---|
| Visibility and light | Visibility aid, reflective vest, flashlight | A stop in low light or poor visibility |
| Basic checks | Tire-pressure gauge, owner’s manual | Checking a warning or confirming tire pressure |
| Common roadside problems | Portable inflator, jumper cables or jump starter | A low tire or a battery that will not start the car |
| Waiting safely | First-aid kit, phone charger or power bank, water | Getting help and remaining comfortable while you wait |
A tire-pressure gauge takes little room and is useful well before you have a roadside problem. Use your vehicle’s recommended tire pressure rather than the maximum pressure printed on the tire. A portable inflator may help with a tire that is simply low on air, but it cannot make a damaged tire safe to drive on. If a tire will not hold air, seek help. The National Highway Traffic Safety Administration’s tire guidance is a useful resource for routine tire care.
Jumper cables require another vehicle and the correct connection procedure. A portable jump starter offers another option, but it must be suitable for your vehicle and maintained according to its instructions. Read your owner’s manual before you need either one. If you are unsure about the procedure or see signs of battery damage, call for assistance instead.
If your vehicle has a spare tire, confirm that its jack, lug wrench, and any wheel-lock key are present and compatible. Locate the designated jack points in your manual. Do not attempt a tire change beside moving traffic or on unstable ground. Some vehicles have a tire repair kit instead of a spare, so find out what yours carries before a flat leaves you guessing.
For short local trips, we would start with visibility items, a flashlight, phone power, and the equipment supplied with your vehicle. Add an inflator or battery-starting equipment when you understand how to use it and have a secure place to store it. A packed trunk is not helpful if you cannot reach the essentials when you stop.
For longer drives or routes with limited services, consider extra water, clothing suited to the weather, and a backup way to power your phone. Review your route and likely conditions before leaving. Secure loose or heavy equipment so it cannot shift around the cabin; keep frequently needed items accessible and larger tools in an appropriate compartment.
Our Basic Tools to Keep in Your Car eBook guide offers a focused starting point for organizing these decisions. Pair a general guide with your vehicle’s manual: the manual tells you what equipment your car has and provides its model-specific procedures. Comfort items are separate from safety equipment. If you bring in-ear headphones for a long trip, use them only when it is safe and legal to do so, and keep your hearing clear when you need to monitor traffic or speak with a responder.
Set a recurring reminder to test your flashlight and power bank, inspect cables or a jump starter, and replace used or expired first-aid supplies. Check an inflator and any spare tire according to their instructions. Before a longer trip, confirm that your phone-charging cable works and that you can reach the items you would need first.
Replace supplies promptly after using them. Revisit the kit when you change vehicles, seasons, or driving routines. A compact kit that matches your car and remains ready is more useful than a larger collection of tools you have never practiced using.
Start with visibility, light, communication, and the equipment supplied with your vehicle. A tire-pressure gauge, inflator, or suitable battery-starting equipment can be useful if you know how to use it safely.
No. Check whether your vehicle has a spare, a tire repair kit, or neither, and follow its manual. Carry compatible battery-starting equipment only if you know how to use it safely.
Check it on a recurring schedule and before longer trips. Test powered items, inspect the spare if equipped, replace used or expired supplies, and update seasonal essentials.
