What to do if…
an ABS or traction-control warning light appears while you are driving in poor weather
Short answer
Keep the vehicle stopped while you assess the warning. If a red brake-system warning is on, braking feels abnormal, or the vehicle is in an unsafe location, call for help and arrange towing rather than resuming the trip.
Do not do these things
- Do not test the warning with hard braking, quick steering, or sudden acceleration on wet, icy, snowy, or low-visibility roads.
- Do not resume the trip merely to see whether the warning clears or to get home.
- Do not assume the vehicle is safe because it still moves or because a warning disappears after a restart.
- Do not stand on the traffic side of the vehicle or attempt a roadside repair in poor visibility.
- Do not rely on warning-light color alone; dashboard meanings vary by vehicle.
What to do now
- Make the stopped position as safe as possible. Turn on the hazard lights. If the vehicle is fully out of traffic and the location is safe, stay belted inside while you assess. If the vehicle could be struck or there is another immediate hazard, leave only if it is safe to do so and move away from the roadway.
- Call for the right help. Call 911 if the vehicle is blocking a traffic lane or there is an immediate danger. If the vehicle is safely out of traffic, contact roadside assistance or a towing service.
- Check the dashboard without driving. Note whether you see an ABS warning, a traction-control or stability-control warning, a red brake-system warning, or a message telling you to stop. Confirm that the parking brake is fully released. Use the vehicle owner’s manual to check the meaning of the symbols for your vehicle.
- Arrange towing if any high-risk sign is present. Do not drive if there is a red brake-system warning, a stop message, smoke, a burning smell, a soft or sinking brake pedal, weaker braking, grinding, or any concern that you cannot re-enter traffic safely.
- Do not resume the trip in poor conditions. If the stopped location becomes dangerous, call 911 and follow the dispatcher’s instructions. Move the vehicle only if it is safe and needed to leave immediate danger.
- Record the warning once you are safe. Take a photo of the dashboard and note the weather, road conditions, and whether the warning appeared before or after any change in braking feel. Share this with the repair shop.
What can wait
- You do not need to identify the exact sensor, module, or repair while you are roadside.
- You do not need to test whether the vehicle can complete the trip.
- You do not need to decide on repair costs or long-term transport plans now.
- A recall check or possible-defect report can wait until you are in a safe place.
Important reassurance
An ABS or traction-control warning does not automatically mean that all braking has failed. Some vehicles may retain conventional braking when an assistance system has a fault, but warning meanings vary and poor conditions reduce your margin for error. Staying stopped, avoiding a roadside test, and arranging help is a sensible response.
Scope note
These are first steps for the earliest safe pause. Later decisions, including whether the vehicle can be driven after inspection, may need help from a qualified repair professional and the vehicle manufacturer’s guidance.
Important note
This is general safety information, not mechanical, legal, financial, medical, therapeutic, or other professional advice. Dashboard symbols and safe next steps vary by vehicle and location.
