> **Quick Answer:** Put the car in neutral and push it to the curb or a parking lot. Turn on your hazard lights immediately. Try restarting once you're clear of traffic. If it won't start after two or three attempts, stop cranking. Check for a dead battery, empty fuel tank, or failed fuel pump. If nothing obvious shows up, call for a tow.

## What To Do
1. **Hit your hazards first.** Do this before anything else. Drivers behind you need to see that something is wrong.
2. **Get the car out of the intersection.** If the car is in drive and dead, shift to neutral. You can push it from behind or, in some cases, let it coast to the curb if there's a slight downhill grade. Ask any passenger to steer while you push. Do not leave it sitting in the lane.
3. **Try to restart it.** Once you're safely out of traffic, turn the key or press the start button. If it cranks but won't fire, wait 30 seconds and try again. Do not crank more than three times. You'll drain the battery and potentially flood a fuel-injected engine.
4. **Read what the car is telling you.** Before your next restart attempt, check a few things:
- Does the dashboard light up normally when you turn the key to "on"? Dim or dead lights point to a battery or alternator issue.
- Is your fuel gauge showing empty or close to it? More common than people admit.
- Is there a check engine light, security light, or oil pressure warning?
5. **Listen when you crank.** A rapid clicking sound almost always means a dead or weak battery. Complete silence with no click can mean a failed starter or totally dead battery. An engine that cranks normally but won't fire points toward fuel delivery or spark. A car that cranks, almost catches, then dies suggests a failing fuel pump.
6. **Do not keep cranking if it's not starting.** Every attempt that fails draws more power from the battery. If it hasn't started in three tries, you're not going to fix it by grinding the starter. You're diagnosing now, not fixing.
7. **Call for a jump start or tow.** If the dashboard lit up dim, try a jump start first. If the gauges looked normal and the engine just wouldn't fire, you likely need a tow to a shop. [A clicking noise with no start is almost always a battery issue](/car-wont-start-clicking-noise-tow-needed/), but a silent failure that won't jump usually means something else failed. For fuel-pump failures specifically, the car often dies at low speeds or idle first, which is exactly what happened to you at that light.
8. **If you have kids in the car**, get them out of the vehicle and onto the sidewalk before you start pushing or calling anyone. [Keep them away from traffic and stay with them](/car-broke-down-with-kids-in-car-safety-steps/).

## Common Causes for This Specific Scenario
A car that dies at a red light and won't restart is usually one of these:
- **Dead or weak battery.** Especially if the car has been harder to start lately or the lights seemed dim.
- **Failed alternator.** The alternator stops charging while driving. The battery runs down slowly, then the car dies. [An alternator failure often gives you warning signs before it leaves you stranded](/alternator-failed-while-driving-what-happens-next/).
- **Empty fuel tank.** The gauge can lie, especially on older vehicles with a bad fuel level sensor.
- **Failed fuel pump.** Often cuts out under load or at idle. The engine will crank normally but not fire.
- **Overheating.** If the temperature gauge was climbing before it died, the engine may have shut down as a protection measure. Do not restart it until it cools. Check for steam or coolant smell.
- **Bad crankshaft position sensor.** The engine cranks fine but won't start. No spark, no fuel injection timing. Common on higher-mileage vehicles.

## Stay Safe
- Stay in your car with your seatbelt on if you cannot get fully off the road. A moving vehicle hitting yours is more survivable when you're buckled.
- If you're partially in an intersection and can't move the car, get out and stand on the sidewalk away from traffic.
- Turn on hazard lights even in daylight. Keep them on until the tow truck arrives.
- At night, stay visible. Stand behind a guardrail if there is one. Do not stand between your car and oncoming traffic.
- Do not accept help from strangers who pull up unsolicited, especially at night. [If you're in an area that feels unsafe, stay in the locked car and call for help](/car-broke-down-bad-neighborhood-night-what-to-do/).
