If your vehicle fails on I-26, I-40 or I-240, the first priority is to get it as far onto the right shoulder as you can, turn on the hazard lights, and decide whether it is safer to wait inside or behind a guardrail. Then call 911 if anyone is hurt or you are in danger, or use a free highway help service or your own roadside provider if the situation is not an emergency. Traffic on these roads is fast, shoulders can be narrow, and a stopped vehicle is one of the most exposed places a driver can be.
The first two minutes
- Do not stop in a lane if you can coast out of it. If the engine dies, use momentum to reach the shoulder or an exit ramp.
- Put the hazard lights on and steer to the right. Pull as far from the traffic lane as the surface allows. Turn the wheels away from traffic so a hit does not push the car into the lane.
- Set the parking brake and shift to park.
- Note your location. Mile markers, exit numbers and the direction of travel are far more useful to a dispatcher than a description of the scenery.
- Decide where to wait. Where there is a guardrail or a bank you can safely stand behind, well off the pavement and away from the car, that is usually better than sitting in a vehicle that could be struck from behind. If there is nowhere safe to stand, such as a steep drop, heavy ice or darkness, staying belted in with the hazards on is the common alternative. Use judgment for the spot you are in.
What North Carolina law says about stopping on a highway
North Carolina's rules on parking on highways, G.S. 20-161, say you may not leave a vehicle on the shoulder of a public highway unless approaching drivers can see it from 200 feet in both directions, and you may not park where you obstruct traffic. A vehicle that is truly disabled, to the point that it is impossible to avoid stopping, gets an exception for the main-traveled portion of the road. The same statute says that when a vehicle is left on a highway right-of-way for 24 hours or more, the investigating officer is treated as the owner's agent for arranging transport and storage. So do not leave a broken-down car on the shoulder for days: it can be removed and stored, and the owner pays for that.
The state's Move Over law, G.S. 20-157, protects the people who come to help you. When an emergency or public service vehicle is stopped within 12 feet of the roadway with warning lights on, approaching drivers must move out of the adjacent lane if they can do so safely, or slow down and be ready to stop. The definition of a public service vehicle includes one assisting motorists or law enforcement with wrecked or disabled vehicles, so a tow truck working a breakdown counts. The basic penalty is an infraction with a $250 fine, and it becomes a criminal offense if the violation causes more than $500 in property damage or injures a responder at the scene. The full wording is in G.S. 20-157 on the General Assembly's statute pages.
Who to call
| Situation | Call | Why |
|---|---|---|
| Injuries, fire, a blocked lane after a crash, or a threat to your safety | 911 | Emergency dispatch sends the right responders |
| Disabled vehicle, no emergency, in an area the Safety Service Patrol covers | *HP from a mobile phone | NCDOT's free Safety Service Patrol can help with flat tires, small amounts of fuel, jump-starts, debris and traffic control |
| Disabled vehicle, no emergency, outside the patrol area | Your roadside provider, insurer or a tow company | They can dispatch a truck to your mile marker |
| Abandoned vehicle you see on the side of the road | The law enforcement non-emergency line | Leave 911 and *HP open for emergencies |
The Safety Service Patrol, also known as the Incident Management Assistance Patrol, is a free NCDOT program. In August 2025 NCDOT announced that its I-26 coverage in the mountains had been extended to about 52 miles, from the South Carolina line to Madison County. Coverage is not statewide, and NCDOT does not promise service at every hour, so check NCDOT's Safety Service Patrol page for the current map. Coverage on I-40 and I-240 around Asheville may be different from I-26.
Using DriveNC and your phone
NCDOT's DriveNC.gov site shows closures, crashes and construction on the interstates. It helps to check before you set off on a mountain trip and while you wait for a truck, since it will show if the road ahead of you is backed up or closed. Keep your phone charged, and if a signal is weak, text your pin and mile marker to a person who can pass the details along.
Common mountain-interstate breakdowns
- Overheating on a long climb. Pull over, shut off the engine, and leave the hood closed for several minutes. Never open a hot radiator cap.
- Overheated brakes on a steep descent. Downshift early to let the engine do the slowing. A burning smell and a soft pedal mean you should stop at the next safe place and wait for the brakes to cool.
- Tire blowout. Hold the wheel steady, ease off the gas, brake gently, and steer to the shoulder. Avoid slamming the brakes.
- Running out of fuel. Fuel stops are spaced out on some stretches. A Safety Service Patrol truck can bring a small amount in covered areas.
For the common small-fix services, the guide to jump starts, lockouts and fuel delivery shows what a roadside technician can do on the spot.
The Blue Ridge Parkway is a different case, with its own rules and patchy phone signal; see what to do if you break down on the Parkway.
If you are towed from the shoulder
If a trooper or deputy arranges the tow because you are blocking traffic, the vehicle will typically go to the tow operator's storage lot. You will be asked to pay towing and storage to release it. The guide to tows after a crash explains how to find the vehicle and what rights you have to contest a police-ordered tow. If you request the tow yourself, the steps in how a tow call works apply, and you can choose the destination.
Frequently Asked Questions
Should I stay in my car or get out when I break down on the interstate?
It depends on the location. If you can stand safely behind a guardrail or well off the pavement, that is usually safer than sitting in a vehicle that can be hit. If there is no safe place to stand, staying inside with your seat belt on and the hazard lights flashing is the usual alternative.
What does *HP do in North Carolina?
In areas where NCDOT's Safety Service Patrol operates, dialing *HP from a mobile phone is the way to request help for a stranded motorist. The service is free and covers basics such as tire changes, small amounts of fuel and jump-starts. Keep *HP for stranded drivers and highway emergencies, and report an abandoned car through a non-emergency line instead.
Can I leave my car on the shoulder overnight?
You should not plan on it. State law says a vehicle left on a highway right-of-way for 24 hours or more may be handled by the investigating officer, including removal and storage at the owner's expense. Arrange a tow as soon as you can.
Do I have to move over for a tow truck on the shoulder?
If it is a vehicle assisting motorists with a disabled vehicle and it is displaying warning lights, the Move Over law applies. Move into a non-adjacent lane if it is safe, or slow down and be ready to stop.
What if I run out of fuel on the interstate?
Treat it like any other breakdown: get to the shoulder, turn on hazards, and call for help. In covered areas the Safety Service Patrol may bring a small amount of fuel; otherwise your roadside provider can deliver some.
