Vehicle Preparedness & Emergency Kits
Difficulty: Beginner
Time to Complete: 40 minutes to read
Overview
Your vehicle is arguably the most versatile emergency tool you own. In a crisis, it can be your shelter, your communication hub, your transport to safety, your power source, and your mobile supply cache. But only if it’s prepared. A vehicle that won’t start in an emergency is worse than useless — it gives you false confidence. This guide covers how to prepare your vehicle for emergencies, what to keep in it at all times, vehicle-specific survival techniques, and how to maintain readiness when you depend on your car in a crisis.
Why This Matters
In every major disaster in living memory, the difference between those who escaped danger and those who were trapped came down to transportation. After Hurricane Katrina, those who could drive left. Those whose cars wouldn’t start, or who didn’t have cars, were stranded for days. During the 2021 Texas freeze, people died in their cars because they kept the engine running for heat (carbon monoxide) or because they ran out of fuel with nowhere to go.
Your car is a steel box with a heater, lights, a radio, and the ability to travel. In an emergency, those capabilities are invaluable. But a car only works if it’s maintained, fuelled, and equipped before the crisis hits.
Vehicle Maintenance: The Foundation
All the kit in the world won’t help if your car doesn’t start. Basic maintenance is your first and most critical preparedness action.
Minimum Maintenance Schedule
| Task | Frequency | Why It Matters | Approximate Cost |
|---|---|---|---|
| Engine oil change | Every 10,000 km or annually | Engine failure = no transport | £50–100 |
| Tyre inspection and rotation | Every 10,000 km | Blowout on a motorway = stranded | £0 (if you check yourself) |
| Tyre pressure check | Monthly | Under-inflated tyres = poor fuel economy, increased blowout risk | Free |
| Battery test | Every 6 months | Dead battery = car won’t start (the #1 cause of breakdowns) | Free (at most garages) |
| Battery terminal cleaning | Annually | Corrosion = poor electrical connection = no start | Free |
| Coolant level and condition | Every 6 months | Overheating = engine damage | £0–20 |
| Brake fluid check | Every oil change | Brake failure = catastrophic | Free |
| Windscreen wiper replacement | Annually (or when streaking) | No visibility in rain = cannot drive safely | £15–30 |
| All fluid levels | Monthly (on your own) | Prevents unexpected failures | Free |
| Belts and hoses inspection | Every oil change | Snapped belt = immediate breakdown | Free to inspect |
The fuel rule: Never let your tank drop below half full. In an emergency, you need every litre. Fuel stations may be without power (pumps are electric) for days. A full tank also gives you a heat source if trapped.
The Fuel Problem
- Petrol station pumps require electricity — grid = power cut at petrol stations
- Credit card systems may be down — carry cash for fuel
- Queues will be massive — leave early
- Fuel storage: Legal limit of 30 litres without notification in the UK — keep approved jerry cans in your garage (not your car)
- Fuel stabiliser: For long-term stored fuel in jerry cans

Survival If Trapped in Your Vehicle
There are several emergency scenarios where you’re trapped: snow, flood, civil unrest, road closure, mechanical failure in a dangerous location.
Winter: Trapped in Snow
DO:
Stay with your vehicle — it’s your shelter and rescuers can see it- Run the engine for heat only 10 minutes per hour
- Slightly open a window on the downwind side for ventilation (prevents CO buildup)
- Clear the exhaust pipe of snow before starting the engine (CO backup = fatal)
- Move your body: arms, legs, stamp feet, clench and release muscles — generates heat
- Put on all available clothing — layer up
- Use floor mats, paper, or cardboard as insulation if available
- Keep your phone on low-power mode; save battery for emergencies
- Signal for help: tie a bright cloth to the antenna, flash hazard lights, use your torch
DO NOT:
Run the engine continuously (carbon monoxide risk)- Run the engine at all if the exhaust is blocked by snow (immediate CO risk)
- Leave the vehicle to seek help unless you can SEE a known safe destination and it’s close
- Eat snow (lowers core body temperature — melt it first)
Carbon monoxide awareness:
- CO is odourless, colourless, tasteless. You won’t know it’s there until you’re symptomatic.
- Early symptoms: headache, dizziness, nausea, weakness, confusion
- If you experience ANY of these: stop the engine, open windows, get fresh air immediately
- CO poisoning kills within minutes at high concentrations
Summer: Trapped in Heat
DO:
- Stay hydrated — ration your water intake (sips, not gulps)
- Stay in the shade — park in shadow if possible before stopping
- Open windows for cross-ventilation if safe to do so
- Use wet cloth on your neck, wrists, and forehead (cools major blood vessels)
- Minimise physical exertion
- Run the AC only briefly to cool the interior, then turn off to save fuel
- Protect children and pets — they overheat much faster than adults
DO NOT:
- Leave children or pets in a parked car in hot weather — even for “just a minute”
- Drink alcohol or caffeinated drinks if they’re all you have (both dehydrate)
- Overexert trying to signal for help in the midday heat
Flooded: Water Rising Around Your Vehicle
This is one of the deadliest driving scenarios.
- If water is rising around your car, leave immediately — don’t wait
- Water as shallow as 30cm can float most vehicles
- If the car is already floating: unbuckle, roll down or break the window (side window, not windscreen), get out
- If the window won’t open: use the headrest prongs — pull out the headrest, insert one prong into the bottom edge of the side window (near the door), lever firmly — the window will shatter
- Get to the highest point you can reach and signal for help
- Never drive through floodwater — “If it’s flooded, forget it” should be your mantra
Vehicle as Power Source
Your car’s battery can charge devices and provide limited power in an emergency.
Charging Devices From Your Car
| Method | Output | Notes |
|---|---|---|
| 12V car charger (USB) | 5V / 2.4A (12W) | Standard — charges phones |
| 12V car charger (USB-C PD) | 5–20V / 3A (60W) | Fast-charges phones, tablets, some laptops |
| 12V → 230V inverter | 150–2,000W | Converts DC to AC for household devices |
Inverter guide:
- 150W inverter — charges laptops, small devices, LED lights — plugs into cigarette lighter
- 500W inverter — above + small TV, small appliances — requires direct battery connection
- 2,000W inverter — full household devices, power tools — requires professional installation
Warning: Running your engine to charge devices consumes approximately 3–5 litres of petrol per hour of idling. In an extended crisis, this burns through your fuel rapidly. Use the car-as-charger sparingly and only when necessary.
Drain risk: Don’t run the engine off the battery without the engine running. A car battery will be dead in 2–4 hours powering a laptop. Always have the engine running (or at minimum running for 10 minutes every 30 minutes) to avoid stranding yourself.
Vehicle Storage Considerations
If you have multiple vehicles or need to store a vehicle for emergency-only use:
- Fuel stabilised with fuel additives (keeps petrol viable for 12–24 months)
- Battery maintained with a trickle charger (or remove and store in a warm place)
- Tyres inflated slightly above normal (prevents flat-spotting)
- Elevated on stands if storing for months (prevents tyre deformation)
- Started and driven for at least 20 minutes every 2–4 weeks (charges battery, circulates oil, prevents seals from drying)
- Moisture control in storage area (silica gel packets inside prevent interior mould)
Alternative Transportation Preparedness
If your primary vehicle is unusable, what are your alternatives?
| Option | Range | Speed | Fuel Needed | Notes |
|---|---|---|---|---|
| Bicycle | 40–100 km/day | 15–25 km/h | None (calories) | Silent, reliable, no fuel needed — essential backup |
| Electric bicycle | 40–80 km per charge | 25 km/h (UK legal limit) | Battery charge | Fast, but requires electricity |
| Walking | 30–40 km/day | 5 km/h | None (calories) | Ultimate backup — always available |
| Motorcycle / moped | 200–400 km | 50–120 km/h | Petrol | Fuel-efficient, but less cargo space |
| Secondary vehicle | Variable | Variable | Fuel | Ideally different fuel type from primary (e.g., diesel car + petrol generator) |
Bicycle preparedness:
- At least one bicycle per household that can carry cargo
- Basic bicycle repair kit (spare inner tube, tyre levers, patch kit, pump, multi-tool)
- Bike lock
- Rear rack or pannier bags for carrying supplies
- Lights and reflective gear
- Keep tyres inflated and chain lubricated
EV-Specific Considerations
Electric vehicles require different emergency planning:
Challenges:
| Challenge | Impact | Mitigation |
|---|---|---|
| No fuel — only electricity | Useless if grid is down | Home solar/battery system, know charging station locations with backup power |
| Charging infrastructure depends on grid | Most public chargers don’t work during grid outages | Know which nearby chargers have solar or battery backup |
| Range anxiety in emergency | May not be able to reach destination | Plan routes with charging stops, keep battery above 50% |
| Can’t be siphoned | Can’t “borrow” range like petrol cars | N/A |
EV Advantages:
- Can power household devices — many EVs have V2L (Vehicle-to-Load) capability providing 230V output
- Silent running — important for low-profile movement
- No exhaust emissions — safe to run in enclosed spaces (for heating/cooling)
- Fewer moving parts — more reliable long-term, less maintenance
