The Mojave is one of the most common places in the country to have car trouble — and one of the worst places to be unprepared for it. Scorching pavement, long distances between services, and summer heat that peaks well above 100°F mean that a blowout or overheated engine can turn into a survival situation faster than you'd expect.
Know what to do before it happens. The physics don't care that you're running late. — G.R.
Blown Tire
Don't panic and don't hit the brakes. Slamming the brakes after a blowout is the most dangerous thing you can do — it amplifies instability and can send the car into a spin.
What to do:
- Grip the wheel firmly with both hands and hold your course
- Ease off the gas gradually — let the car slow on its own momentum
- Steer gently toward the right shoulder — smooth, controlled input only
- Once slowed to a safe speed, signal and ease off the road as far as possible
- Stop fully off the pavement on level ground, well clear of traffic
A front blowout will yank the steering toward the blown side. Resist the pull — don't overcorrect. A rear blowout may cause the back end to fishtail. Hold the wheel steady and resist the urge to brake.
Once stopped:
- Turn on your hazard lights immediately
- Set out warning triangles or flares if you have them — first one 10 feet behind the car, second 100 feet back, third 100–300 feet depending on road type
- Raise the hood to signal distress
- Stay well away from the traffic side of the vehicle when changing the tire — exit from the passenger side when possible
- If you're on a highway shoulder with fast traffic and can't safely change the tire, stay in the car with your seatbelt on and call for help — a replaced tire isn't worth being hit by a passing vehicle
Before any Mojave trip: Check that your spare is inflated. Many drivers discover their spare is flat when they need it. Carry a portable 12V tire inflator and a plug kit.

Overheated Engine
The signs come before the crisis: temperature gauge climbing, steam rising from under the hood (it looks like smoke — it isn't), a warning light, or a sweet, chemical smell from the vents. Don't wait for the needle to pin.
Step-by-step:
- Turn the A/C off immediately — it puts load on the engine and makes overheating worse
- Turn the heater on full blast — counterintuitive, but it pulls heat from the engine into the cabin. Roll windows down if needed
- Pull over as soon as it's safe — find a flat spot off the road. Don't push it to a service station if the gauge is in the red
- Shut the engine off — let it sit for at least 15–30 minutes. Do not restart it to "check" how it's doing
- Do not open the radiator cap — the cooling system is pressurized. A hot radiator cap can spray scalding coolant and steam with enough force to cause serious burns. Wait until the engine is completely cool before touching it
- Once cool, check the coolant reservoir first — the translucent plastic tank near the radiator, not the cap itself. If it's low, add coolant or water slowly. If you can't identify a leak or the problem, call for a tow
If the gauge spikes and you can't pull over immediately: Shift to neutral and rev the engine lightly if you're in stop-and-go traffic — this speeds up the water pump and pulls more air through the radiator. It buys time.
Do not drive more than a short distance on an overheated engine. A few minutes of running hot can warp the cylinder head or crack the block — a repair that costs far more than a tow.

Stranded — Broke Down or Stuck
Stay with the vehicle. This is the rule.
Every desert safety authority — NPS Death Valley, NPS Mojave National Preserve, NPS Big Bend, AAA — says the same thing: a vehicle is dramatically easier for rescuers to locate than a person on foot. A car on a road is visible from the air and from miles away. A person walking through the desert is not.
When you stop:
- Turn on your hazard lights
- Raise the hood — the universal signal for a breakdown
- If you have brightly colored clothing, hang it from the antenna or door handle
- Place a large X on the ground using rocks, gear, or any dark material visible from above — the standard ground-to-air distress signal
- Leave a dated note on the dashboard: your name, the problem, your cell number, emergency contact, the time you wrote the note, and where you plan to go if you leave
Staying alive while you wait:
- Get out of a closed car in extreme heat — the greenhouse effect inside a parked car can be lethal. A car in the Mojave sun can reach 150°F+ inside within an hour
- Sit in the shade of the vehicle — on the shaded side, not inside. Use a propped-open door, a tarp, or a space blanket as a shade extension
- Avoid strenuous activity during peak heat — work, signal, and move only in the cooler early morning or after sundown
- Drink your water — rationing too aggressively while your body is overheating is a common and dangerous mistake. Shade and stillness reduce how much you need; drink steadily regardless
- The NPS standard is at least one gallon of water per person per day in desert heat — more if you're exerting yourself
To walk or not to walk: If you know with certainty that help is within a short, safe distance — and you have enough water to make it — walking is a calculated option. But the desert makes distances look shorter than they are, and a two-mile walk in 110°F heat requires more water than most people carry.
If you walk, do it after sundown when temperatures drop. Stay on the road. Take everything useful. Leave your note with the vehicle. Tell someone your direction before you leave.
Calling for help:
- Dial 911 — cell service in the Mojave is limited and unpredictable, but try
- Text if a call won't go through — texts sometimes send when voice calls won't
- Move to higher ground to get signal if you're in a low area — a short walk uphill may be all it takes
- If you carry a personal locator beacon (PLB) or satellite communicator, this is exactly what it's for

Before You Go — Vehicle Checklist
Most desert breakdowns are preventable. Check these before any trip into the Mojave.
In the trunk:
- Spare tire — inflated, and you know how to use it
- Jack and lug wrench — in the car, not missing
- Portable 12V tire inflator and tire plug kit
- Jumper cables or a portable lithium jump-starter pack
- Extra coolant — one small bottle is enough to matter
- Warning triangles or road flares — 3 minimum
- Basic tools: multi-tool, duct tape, zip ties
For you and your passengers:
- Water — at least one gallon per person, plus extra in case you're stuck overnight
- Extra water for the car — a gallon in a jug for the radiator if needed
- Snacks with some salt — helps in heat
- A paper map of the area — GPS fails, phones die
- Flashlight or headlamp with fresh batteries
- Sunscreen and a hat
- A fully charged phone — and a portable battery pack
Tell someone your plan — route, destination, vehicle description, and when you expect to be back. If you don't check in, they know to send help. In the Mojave, that's not paranoia. That's just how the math works.
