> **Quick Answer:** Stay in your car with your seatbelt on, turn on your hazard lights immediately, and call 911. Most highway tunnels have emergency phones mounted on the walls every 150 to 200 feet. Do not get out and walk unless there is fire or visible smoke inside the vehicle. Tunnel operators monitor with cameras and will dispatch help fast.
## What Do I Do the Moment My Car Stops in a Tunnel?
Keep your seatbelt on and hit your hazard lights before you do anything else. Your first instinct will be to get out and look under the hood. Don't. The tunnel is a confined space with live traffic moving at speed, no shoulder in many sections, and poor visibility for other drivers. You are safer inside a stationary car than standing next to one.
Once hazards are on, call 911. Give them the tunnel name, the direction you were traveling (northbound, southbound, etc.), and any mile marker or light pole number you can see on the wall. Tunnel operators work directly with emergency dispatch and can halt traffic flow into the tube or deploy their own response teams within minutes.
If your car is still running and you can move it, edge it as far right as possible toward the wall. Even a few feet of extra clearance reduces the risk of a side-swipe significantly.
## Is It Safe to Get Out of My Car Inside a Tunnel?
Only get out if there is fire or thick smoke coming from your vehicle. Those are the two conditions that justify the risk of standing in a live traffic tunnel. A breakdown with no fire: stay put, seatbelt on, and wait.
If you must exit, get out on the passenger side (away from traffic), press yourself against the wall, and move toward the nearest emergency exit door. These are spaced roughly every 300 feet in modern highway tunnels, marked with green illuminated signs. They lead to pressurized evacuation corridors that are separated from the roadway.
Never stand behind your vehicle. Rear-end collisions into stopped tunnel vehicles are among the most dangerous tunnel incidents, because drivers do not expect a stopped car and reaction distances are short.
## How Do I Call for Help if I Have No Cell Signal?
Use the tunnel's hardwired emergency phone. These bright orange or yellow phones are bolted to the tunnel wall at regular intervals, usually every 150 to 200 feet. Pick it up. There is no dialing required. It connects directly to tunnel operations or emergency dispatch.
If you do have a cell signal, 911 is always the right first call. You can also try 511, the nationwide traffic information line available in most states, which can route you to the correct DOT operations center. The Lincoln Tunnel in New Jersey and the Eisenhower Tunnel on I-70 in Colorado, as two well-known examples, both have tunnel-specific emergency response teams that are separate from standard highway patrol.
Do not spend time calling a tow company yourself. Tow access inside an active tunnel requires tunnel authority clearance. The dispatcher will coordinate that for you.
## Will a Tow Truck Even Be Able to Get to Me in a Tunnel?
Yes, but the tunnel authority controls access and timing. Once emergency responders confirm your location, they will typically close one or both lanes and bring in a tow truck cleared to work in the tube. This process is usually faster than a standard highway breakdown because tunnel operators treat any stopped vehicle as a priority incident.

standard local tow. Tunnel response requires a licensed operator, sometimes a flatbed if it's a tight space, and the tow company may charge a premium for restricted-access jobs. If you have roadside assistance through AAA or your insurance carrier, report the breakdown to them after you have contacted 911, and let them know it's a tunnel situation. Coverage rules still apply, but the coordination goes through the tunnel authority first. For context on what a tow might run without coverage, see [how much does a tow truck cost with no insurance](/how-much-does-a-tow-truck-cost-with-no-insurance/).
## What If There's Smoke or Something Burning Inside the Tunnel?
Get out immediately and move to the nearest emergency exit. Tunnel fires escalate faster than open-air fires because there is no ventilation escape route and heat and smoke build rapidly in the enclosed space.
If you see or smell burning, do not try to restart the car, do not open the hood, and do not wait to see if it clears. Leave everything in the car. Use the emergency exit corridor and do not re-enter the tunnel for any reason.
Once you are in the evacuation corridor, move away from the incident and toward the exit end. Follow any directional signs. Emergency responders will come to you.

## Common Questions
**Q: Should I turn my car off if it breaks down in a tunnel?**
A: Yes. If the engine has failed or you can safely stop it, turn it off. This reduces fire risk from fuel leaks near hot components. Keep your hazards and interior lights on so you remain visible.
**Q: What if I break down in a tunnel and traffic is backed up behind me?**
A: Stay in the car with your seatbelt fastened. Do not get out to wave traffic around you. Call 911 immediately. Tunnel operators will see the backup on camera and respond. Your job is to be visible and stationary, not to direct traffic.
**Q: Can I push my car out of the tunnel?**
A: No. Pushing a car in a live traffic tunnel puts you and any helpers in serious danger. Wait for professional responders who will have the proper equipment and lane control to move the vehicle safely.
**Q: How long will I be stuck waiting in a tunnel breakdown?**
A: Most tunnel authorities treat stopped vehicles as priority calls and respond within 10 to 20 minutes. This is faster than a typical highway shoulder wait, which can stretch to 45 minutes or more. See [how long can you wait on the side of a highway for a tow](/how-long-can-you-wait-on-side-of-highway-for-tow/) for comparison on open-road waits.
**Q: What warning lights might have predicted this breakdown?**
A: A flashing check engine light combined with shaking, a battery warning light, or an oil pressure warning light are all signs a breakdown is coming soon. If you see any of these before entering a tunnel, pull over before you go in. Entering a tunnel with an active warning light is a gamble worth avoiding. The [engine oil pressure warning light](/engine-oil-pressure-warning-light-came-on-while-driving/) post explains exactly what that light means and how fast you need to act.
