Car Breaks Down on Highway: 10-Step Safety Guide

Your Car Breaks Down on the Highway—What's Your First Move?

A car breaking down on the highway is stressful. But panic won't help you. The first 60 seconds set the tone for everything that follows.

Here's the truth: most highway breakdowns end safely when you follow a clear plan. You need to know the steps before it happens. Let's walk through exactly what to do.

Step 1: Turn On Your Hazard Lights Right Now

Your hazard lights are your first line of defense. They alert other drivers that something's wrong. Turn them on immediately when you feel your car losing power or notice warning signs.

Don't wait. Don't think about it. Just flip that switch. Other drivers need to see you're in trouble. This simple action cuts your risk of being hit from behind.

Keep those lights on until help arrives. They stay on even after you've pulled over. They keep working while you're inside your vehicle.

Step 2: Slow Down Gradually and Move to the Shoulder

Resist the urge to brake hard. Sudden braking causes accidents. Instead, ease off the gas pedal slowly. Let your car coast.

Check your mirrors. Signal early. Move to the right shoulder as gently as you can. If you're on a busy freeway, this takes patience. But it's worth it.

Get as far from traffic as possible. Aim for the widest part of the shoulder. Distance from moving cars equals safety.

Step 3: Stay Inside Your Vehicle With Doors Locked

This is non-negotiable: stay inside your car with the doors locked. This isn't paranoia. It's smart thinking.

Your vehicle is a protective barrier. Standing outside exposes you to speeding traffic. Locked doors protect you from unexpected approaches. Keep your seatbelt on too.

Turn off the engine. Turn on interior lights if it's dark. Make yourself visible to emergency responders. They'll know someone's inside.

Step 4: Call 911 or Your Roadside Assistance Provider

Once you're safely pulled over, make the call. If you're injured or feel unsafe, call 911 first. Police can block traffic and protect you.

If it's a simple breakdown, call your roadside assistance provider. That might be AAA, your insurance company, or a towing service. Have your membership number ready.

Tell them exactly where you are. Use mile markers if visible. Describe your vehicle color and make. Be clear about your situation—engine won't start, flat tire, smoke, whatever it is.

If you don't have roadside assistance, call a local towing company. Find towing services near you through trusted providers who operate in your area.

Step 5: Turn Off the Engine and Hazard Lights (After Waiting 5 Minutes)

After you've called for help and you're safely parked, wait about 5 minutes. Then turn off your engine. This prevents fuel leaks and reduces fire risk.

You can turn off hazard lights at this point if you want to save your battery. But leave them on if you're worried about visibility. Battery drain matters less than being seen.

Keep your phone charged. If your battery is low, turn off unnecessary apps. You need that phone for updates from roadside assistance.

Step 6: Set Up a Visible Warning—If It's Safe to Exit

Only exit your vehicle if it's absolutely safe. Check traffic in both directions. Make sure no cars are approaching.

If you have an emergency kit with reflective triangles or flares, place them 10 feet behind your car. This gives drivers extra warning. But don't risk your life doing this.

In most cases, staying inside your locked car is safer than getting out. Trust your gut. If traffic feels heavy or fast, stay put.

Step 7: Communicate With Oncoming Help and Stay Alert

When the tow truck arrives, stay calm. The driver will assess your situation. Answer questions about what happened before your car breaks down on the highway.

Ask for their identification. Real towing companies display licenses and insurance information. Learn how to choose a reliable tow truck company so you know what to expect.

Before they hook up your car, discuss the destination. Ask about pricing. Get an estimate. Check current towing costs in 2025 so you're not surprised by the bill.

Step 8: Know Your Rights During the Tow

You have consumer protections when your car breaks down on the highway. The tow operator must follow safe practices. They can't charge you surprise fees.

Never pay in cash before the tow is complete. Ask for an itemized invoice. Get a receipt. Take photos of your vehicle before and after towing.

Different states have different rules about what tow companies can charge. Review towing laws by state to understand your specific protections.

Step 9: Document Everything for Insurance and Records

Take photos of your vehicle on the shoulder. Capture the location, damage, and surrounding traffic. This helps with insurance claims later.

Get the tow truck driver's name, company name, and phone number. Write down the tow truck's license plate. Note the time and date.

Keep every receipt and invoice. These are proof of what happened. If damage occurs during towing, you'll need this documentation. Learn how to file a towing damage claim if something goes wrong.

Step 10: Arrange Transportation and Review Your Options

Once your car is towed, you need a way home. Ask the tow company if they offer rides. Some do. Others don't. Plan ahead.

Call a friend or family member. Use a rideshare app. Many people don't think about this step until they're stranded. That's a mistake.

Ask the towing company where they're taking your car. Get the shop address and phone number. Follow up with them about repairs and timelines.

How to Prevent Your Car From Breaking Down on the Highway

The best breakdown is the one that never happens. Regular maintenance prevents most roadside emergencies. Check your fluids monthly. Rotate your tires every 5,000 miles.

Keep your battery tested annually. Replace worn brake pads before they fail. Check hose and belt condition. These small steps save you from sitting on the shoulder.

Pack an emergency roadside kit with jumper cables, flashlights, first aid supplies, and a phone charger. This kit turns a bad day into a manageable one.

What to Do If Your Car Starts Smoking or Overheating

If you see smoke or smell burning, treat it as an emergency. Turn on hazard lights. Move to the shoulder immediately. Turn off the engine.

Stay inside your locked car. Call 911. Don't open the hood. Overheated engines are dangerous. Steam can cause serious burns.

Wait for professional help. Don't try to add coolant or water yourself. Let firefighters or tow operators handle it. Your safety matters more than your car.

When Should You Call a Tow Truck vs. Trying a DIY Fix?

On the highway, the answer is simple: call a tow truck. The highway is no place for DIY repairs. Even small fixes put you at risk.

Standing outside your car near traffic is dangerous. Other drivers get distracted. Accidents happen in seconds. Learn when to call a tow truck versus attempting DIY fixes for your specific situation.

The only exception: if you have a flat tire and feel comfortable changing it safely, you can try. But if traffic is heavy or visibility is poor, call for help instead.

Understanding Towing Costs When You're on the Highway

Highway towing costs more than local towing. Longer distances mean higher bills. Most highway tows run between $75 and $150 for the first 5 miles, then $3 to $5 per additional mile.

Specialized tows—flatbed trucks for luxury cars, for example—cost more. Emergency calls at night or on holidays carry surcharges. Ask for pricing before they hook up your car.

Check your insurance policy. Many insurance plans cover roadside assistance. AAA memberships include towing. Some credit cards offer roadside benefits. You might not pay anything.

If you don't have coverage, review complete 2025 towing cost pricing to understand what you'll owe. Get a written estimate. Don't be surprised at the register.

What Type of Tow Truck Will Arrive?

Different situations call for different tow trucks. A flatbed truck is safest for luxury or low-clearance vehicles. A wheel-lift truck works for standard cars and pickups.

Integrated tow trucks handle lighter loads. Rotators manage complex rescues. The towing company will send the right truck for your vehicle type and situation.

Learn about the different types of tow trucks so you understand what's arriving and why. This knowledge helps you ask smart questions and feel in control.
