Quick Answer: Turn on your hazard lights, steer to the right wall or shoulder if you have any momentum left, and shift to neutral. Stay buckled inside with the doors closed unless there’s smoke or fire. Call 911, not a tow company first. Tunnels have cameras and operators who can close lanes and send help. Exit only if the car is on fire or you can’t be seen.
Should I Stay in My Car or Get Out?
Stay in the car, belted in, unless you smell smoke, see flames, or the car is stopped in a lane where it could be hit before help arrives. In a tunnel, a stalled vehicle is hard to see until drivers are on top of it, and a person walking is far more vulnerable than a person in a steel cabin.
If you must get out, exit on the side away from traffic and walk to the nearest emergency walkway or refuge. Most road tunnels have a raised curb or walkway along the wall. Leave your phone and keys with you. Do not stand behind or between vehicles.
What Do I Do in the First 30 Seconds?
Hazard lights on first, then coast. If the engine died while moving, you still have momentum, so use it to reach the right wall, a shoulder, or an emergency pull-out.
- Hit the hazards. Leave headlights on too. Your taillights are what the car behind you sees.
- Brake firmly and steer early. With the engine off, power steering and power brakes lose assist. The wheel gets heavy and the pedal gets stiff. It still works. Push harder and don’t pump it.
- Shift to neutral if the engine won’t restart, so you can keep rolling.
- Try one restart in neutral or park. If it catches, drive out slowly and stop where a mechanic can look at it. If it doesn’t, stop cranking. You’re draining the battery your hazards depend on.
- Set the parking brake once you’ve stopped.
If traffic is stopped around you, the same rules apply. Hazards on, belted in, wait for help.
Who Do I Call When My Car Dies in a Tunnel?
Call 911 first. Tunnel operators monitor cameras around the clock and can close a lane, dispatch a service patrol, or send police to protect your car. A private tow truck can’t legally or safely reach you quickly inside a tunnel and may not be allowed to enter at all.
Cell service can drop out inside long tunnels. If you have no signal, look for the emergency call boxes mounted on the walls. They connect straight to the tunnel control room. You can also check your state DOT’s traffic app or dial 511 for road conditions once you’re out and safe.
Tell the dispatcher three things: which tunnel, which direction you were traveling, and which lane you’re in. If you passed a mile marker, cross-passage number, or exit sign before entering, say that too.
Once the tunnel is clear and your car is out, then call your roadside provider. If you’re covered, check how your plan handles it. Our guide on how many times you can use GEICO roadside assistance covers the limits some policies carry.
Why Do Cars Die in Tunnels, and Is It Dangerous?

ccur underground. The tunnel itself rarely causes the failure. The danger is the location: no shoulder, limited visibility, and fumes that build up when engines idle in a closed space.
The common culprits:
- Alternator failure. The battery runs the car until it’s drained, then everything dies at once. See alternator died while driving.
- Fuel pump failure. The engine sputters, loses power, then quits. Read about fuel pump failure on the highway.
- Out of gas. Easy to miss when you’re focused on traffic.
- Overheating. Stop-and-go traffic in a tunnel with poor airflow can push a marginal cooling system over the edge.
Carbon monoxide is the underrated risk. If you’re stuck for a long time with the engine running, don’t idle it. A running engine in a closed tunnel adds exhaust fast. If you feel dizzy or get a headache, tell the dispatcher and get to fresh air.
How Much Will It Cost to Get Towed Out of a Tunnel?
Expect a standard tow rate, sometimes less. In many tunnels the first tow is handled by a state or agency service patrol, and some are free or heavily discounted because the priority is clearing the lane. If a private operator is dispatched, you’ll pay normal rates for your area, with possible surcharges for difficult recovery or after-hours service.
Ask the dispatcher whether the tunnel has a free or contracted service. If you’re quoted a price, ask whether it’s flat or per mile before you agree. Compare your area’s rates in our city breakdowns, like towing cost in Boston or towing cost in Seattle with no insurance.

Common Questions
Q: Should I push my car out of a tunnel myself? A: Only if it’s a short distance, the car is in a live lane, and you have help and can do it safely. Never push alone in moving traffic. Call 911 and let the operators close the lane.
Q: What if I have no cell signal in the tunnel? A: Use the emergency call box on the tunnel wall. It connects to the control room. Keep your hazards on and stay in the car until you reach someone.
Q: Can I just leave the car and walk out? A: Only if there’s fire, smoke, or an immediate collision risk. Otherwise, a car is safer than a walkway next to moving traffic. If you must walk, use the marked emergency walkway.
Q: Will the tunnel operators tow me for free? A: Sometimes. Many tunnels have a service patrol that clears stalled vehicles at little or no cost, mainly to reopen the lane. Ask the dispatcher what applies to that tunnel.
Q: My car restarted. Can I just keep driving? A: Drive out of the tunnel slowly, then pull into a safe spot and have it checked. A car that dies once can die again. Don’t drive it on a highway until you know why it stalled.
