What to Do After a Car Breakdown: A Step-by-Step Checklist

Adrenaline narrows attention. When you're on the shoulder with hazards on, your judgment is compromised, especially at night or in bad weather. This is exactly why a pre-built checklist matters: not because the steps are clever, but because nobody remembers them under stress.

Step 1, Get off the road safely

• Move the vehicle as far onto the shoulder as possible. If you can reach an exit ramp or a wide pull-out, prefer that over a narrow shoulder.
• Turn on hazard lights immediately, even before you fully stop.
• Turn the steering wheel away from traffic and engage the parking brake.

Step 2, Make yourself visible

• If you have reflective triangles, place them at 50, 100, and 200 feet behind the car. The 200-foot triangle gives drivers at 65 mph about 2 seconds of warning.
• Open the hood as a distress signal only on slow roads or rural shoulders. On a highway, an open hood can hide you from approaching drivers.
• At night, a flashing flashlight or a road flare significantly improves visibility.

What to do when your car breaks down on the highway

On a busy highway, the safest position is inside the vehicle with your seatbelt on. Cars getting hit on the shoulder by inattentive drivers is a leading cause of roadside fatalities, far more dangerous than waiting inside a steel cage.

Specifically:

• Stay buckled in. Yes, while parked.
• If you must exit (smell of smoke, fuel, or fire), exit on thepassenger side, away from traffic, and walk well clear of the vehicle to the far side of any guardrail.
• Don't stand between vehicles or behind the breakdown vehicle — that's the highest-risk position.

Step 3, Call for the right help

The decision is binary:

• Call 911 if there's any injury, smoke or fire, blocked travel lanes, hostile situation, or you're in active traffic and can't pull off safely. Police clear lanes faster than tow operators do.
• Call roadside assistance / a tow company for a non-emergency mechanical issue on a safe shoulder.

Use our towing cost calculator to estimate the bill before dispatch quotes you, and contact AM Towing for 24/7 dispatch in our service area.

Common breakdown scenarios, exact steps

Flat tire

1. Pull onto a flat, hard surface well off the road.
2. Hazards on, parking brake engaged.
3. Loosen the lug nuts a quarter turn before jacking the car up.
4. Jack at the manufacturer's lift point, swap the flat for the spare, hand-tighten lug nuts.
5. Lower the vehicle and torque the lug nuts in a star pattern.
6. Check spare PSI — most compact spares are limited to 50 mph for short distances.

Dead battery

1. Turn off ignition and all accessories.
2. Park a working vehicle close to yours, nose-to-nose, no contact.
3. Connect red clamp to dead battery's positive (+) terminal.
4. Connect the other red clamp to the working battery's positive (+).
5. Connect black clamp to the working battery's negative (–).
6. Connect the final black clamp to a clean, unpainted metal surface on the dead car (NOT the battery).
7. Start working car, run for 2–3 minutes.
8. Start your car. Drive at least 20 minutes to fully recharge, idling isn't enough, especially in cold weather.

Out of fuel

1. Coast as far onto the shoulder as you safely can.
2. Hazards on, parking brake engaged.
3. Stay in the vehicle on a highway.
4. Call roadside assistance for fuel delivery, or a friend who can bring a marked fuel can.
5. After refueling, turn the key to "on" for 5 seconds before starting to prime the fuel pump.
6. Refill at the next station, running fuel pumps dry can damage them over time.

The interactive version

For an interactive checklist where you can tap each step as you complete it, use our roadside emergency checklist. Pick your situation (breakdown, accident, flat tire, dead battery, out of fuel) and the right list shows up. Print one for the glove box too, your phone might be dead when you actually need it.

If there was a collision, not just a breakdown

Add two more steps to the standard breakdown sequence:

• Build a damage report with the damage checklist generator within 24 hours.
• Run the insurance claim readiness checker before you file, it tells you exactly what's missing.
