Traction Control Light: Why It's On and What to Do
Written by Muneeb Rana · Last updated 21 October 2026
Quick answer: A traction control light that flashes briefly while you drive is normal: it shows the system is cutting power or braking a wheel to stop it spinning. If the light stays on, the system has been switched off or has a fault, often a wheel-speed sensor shared with the ABS. Drive gently and have it checked.
TL;DR
- Colour: Amber/yellow.
- Flashing briefly is normal; staying on means a fault or the system is switched off.
- Fix the cause rather than just clearing the light, and log the repair.
The traction control light is one of the dashboard warnings drivers search for most. This guide covers what it looks like, what it means, how urgent it is and what to do, in plain English. Your owner's manual has the exact symbol and advice for your car.
What does the traction control light look like?
| Symbol | A car with wavy skid lines behind it |
| Colour | Amber/yellow |
| How urgent | Flashing briefly is normal; staying on means a fault or the system is switched off. |
Warning lights follow a rough traffic-light code: red means a serious problem or safety issue, so stop when it's safe; amber or yellow means something needs attention soon; green or blue is information only. See the full dashboard warning lights guide for every common symbol.
What the traction control light means
Some cars use separate symbols for traction control and electronic stability control (ESC). Your owner's manual shows which is which.
Common causes:
- The system is working on a slippery road (flashing)
- The traction control button was pressed (often a light with OFF)
- A faulty wheel-speed sensor
- A steering angle sensor fault
- An ABS fault, since the systems share hardware
What to do when the traction control light comes on
- If it's flashing on a slippery road, ease off the accelerator.
- If it's steady, check you haven't switched the system off.
- Restart the car to see if it clears.
- If it stays on, get the codes read, especially if the ABS light is also on.
- Log the repair.
Can you drive with the traction control light on?
Yes, carefully. Without traction or stability control, take extra care in rain, snow and on bends.
If you're not sure, treat it as the more serious case. A tow costs far less than a ruined engine, gearbox or set of brakes. If several warning lights come on at once, that often points to an electrical or charging problem; see the check engine light guide and the battery light page.
How to reset or clear it
Don't just clear the light. Most warning lights go out on their own once the fault is fixed, sometimes after a few drive cycles. Clearing a code with a scanner without fixing the cause only hides the problem until it returns, and it can make an emissions test fail because the car's readiness monitors reset.
Keep a record of warning lights and repairs
Write down the date, odometer reading, what the light looked like, the fault code if you had it read, and what fixed it. If the same light comes back, that history saves diagnosis time and money. In CarO you can log the repair and its cost in the car repair log, and set a follow-up with the service reminder tool. For a routine check that catches problems before a light comes on, use our car maintenance checklist. Related: ABS light and wheel alignment guide.

FAQ
What does the traction control light mean?
A traction control light that flashes briefly while you drive is normal: it shows the system is cutting power or braking a wheel to stop it spinning.
Is it safe to drive with the traction control light on?
Yes, carefully. Without traction or stability control, take extra care in rain, snow and on bends.
What colour is the traction control light?
Amber/yellow. Red warnings mean stop when safe, amber means get it checked soon, and green or blue lights are information only.
How do I turn off the traction control light?
Fix the underlying cause; the light usually goes out by itself, sometimes after a few drive cycles. Clearing the code without a repair only hides the problem.
How much does it cost to fix the traction control light?
It depends entirely on the cause, from nothing for a loose cap or released parking brake to a major repair. Get the fault diagnosed and ask for an itemized estimate before approving work.
