> **Quick Answer:** Pull over immediately and shut the engine off. Do not try to drive through it. If the temperature gauge is pegged or you see steam, you need a tow, not a cooldown. Driving an overheating engine through stop-and-go traffic, even for a few more blocks, can warp the cylinder head or crack the engine block. Call a tow truck now and let the engine cool before anyone opens the hood.
## What Do I Do Right Now If My Car Is Overheating in Traffic?
Get out of traffic as fast as safely possible and kill the engine. That is the only move that stops the damage clock. If you are boxed in and cannot pull over, turn off the AC, turn the heater and blower to maximum, and crack the windows. That pulls heat out of the engine bay into the cabin and buys you maybe two or three minutes to reach a shoulder, parking lot, or side street. The moment you can stop safely, do it.
Once stopped: leave the engine off, stay in the car if you are on a busy road, and do not open the hood for at least 15 minutes. Coolant in an overheated system is under pressure. Pulling the radiator cap or the overflow reservoir cap while it is hot can send scalding fluid straight at your face.
## How Do I Know If I Need a Tow or Can I Just Let It Cool Down?
If steam or smoke came from under the hood, you need a tow. Full stop. Steam means coolant is already boiling out of the system, which means you have lost enough coolant pressure that driving again risks serious engine damage. Check for these after the engine cools for 20 minutes: a low or empty coolant overflow reservoir, coolant puddle under the car, or a burning sweet smell. Any one of those means the car should go on a flatbed, not back on the road.
If the gauge climbed high but came back down, no steam appeared, and the coolant level looks normal, you may have a thermostat issue or a momentary blockage. You can try restarting after a full cooldown, watch the gauge closely, and limp carefully to a shop. But if the gauge climbs again within the first mile, pull over again and call a tow. You are not going to win that fight. See [Car Overheating Steam Coming Out: Tow or Drive?](/car-overheating-steam-coming-out-tow-or-drive/) for a more detailed breakdown of where the line is.
## What Does an Emergency Tow Cost When You Are Stuck in Traffic?
Most local tows run $75 to $150 for the first five miles, plus $3 to $7 per mile after that. Hook-up fees, after-hours dispatch, and urban congestion pricing can push a short city tow to $200 or more. If you need a flatbed specifically (recommended for overheating situations where the cause is unknown), add $25 to $50 over a wheel-lift rate in most markets.
Your insurance roadside add-on or a service like AAA can cut that cost to zero or close to it, depending on your plan limits. Check your insurer's app right now while you are waiting, before you call a private tow company.

## Is It Safe to Stay in My Car or Should I Get Out?
Stay in the car if you are on a high-speed road or in dense traffic. Getting out on a busy street is more dangerous than the breakdown itself. Turn on your hazard lights the moment you start pulling over, before you fully stop, so traffic has time to react.
If you are on a surface street with a wide sidewalk and foot traffic is nearby, getting out and stepping onto the curb is fine. If you are on an interstate or urban freeway, stay belted in the passenger side of the car and call for help. A car that

gets rear-ended absorbs the impact better than a person standing behind it. Place road flares or a reflective triangle at least 200 feet behind the vehicle if you have them and can do so without stepping into a travel lane. For guidance on exactly which warning device to use, [Emergency Triangle vs Flares: Which Is Safer on the Highway?](/emergency-triangle-vs-flares-which-is-safer-on-highway/) covers the tradeoffs clearly.
## Could I Have Prevented This and What Repair Am I Looking At?
Overheating in traffic is almost always caused by one of four things: low coolant due to a slow leak, a failed water pump, a clogged radiator, or a stuck thermostat. Stop-and-go traffic is harder on the cooling system than highway driving because you lose the ram-air effect through the radiator grille. If your cooling fan is also failing, city traffic will expose it fast.
Repair costs range widely. A stuck thermostat is a $150 to $350 fix at most shops, parts included. A water pump runs $300 to $750 depending on whether it is timing-belt-driven (which means the belt gets replaced at the same time). A clogged radiator flush is $100 to $200. A blown head gasket, which is what happens when you keep driving an overheating engine, starts around $1,500 and can exceed $3,000. The tow is always cheaper than the head gasket.

## Common Questions
**Q: Can I add water to the radiator to cool it down and drive to a shop?**
A: Only if you are completely out of coolant, the engine has fully cooled, and you are more than a few miles from help. Tap water works short-term but lacks the anti-corrosion and boiling-point additives in coolant. Do not pour anything into a hot radiator. If steam came out, skip this step and call a tow.
**Q: My temperature gauge went back to normal after I stopped. Can I drive now?**
A: Possibly, but carefully. Wait at least 20 minutes, check the coolant level in the overflow reservoir (not the radiator cap), and start the car. If the gauge stays in the normal range and you see no leaks or steam, you can try driving to a nearby shop, but watch the gauge every 30 seconds. If it climbs again, pull over immediately.
**Q: Will my insurance cover the tow if my car overheats in traffic?**
A: It depends on your policy. Roadside assistance add-ons through most major insurers cover towing due to mechanical breakdown, which includes overheating. Check your insurer's app or call their roadside line directly. Some plans cap the tow distance at 15 or 25 miles, so confirm that before dispatch.
**Q: How long does it take a tow truck to arrive in heavy traffic?**
A: In dense urban traffic, expect 30 to 60 minutes, sometimes longer during rush hour. Call as soon as you are safely stopped, not after you have waited to see if the car cools down enough to drive. Getting in the queue early saves you time.
**Q: What if my car won't start again after it overheated and cooled down?**
A: A no-start after overheating usually means the engine hydrolocked from coolant leaking into a cylinder, or the heat warped something enough to kill compression. Do not crank it repeatedly. Call a tow and tell the shop the car overheated before it stopped starting. [Car Won't Start After Overheating: Do I Need a Tow?](/car-wont-start-after-overheating-do-i-need-tow/) walks through exactly what is likely happening.
