What to do if…
an ABS or traction-control warning appears and you have pulled over safely in poor conditions

Short answer

Stay safe where you are and assume your ABS/traction/stability help may be reduced or unavailable. If any red brake warning appears or braking feels abnormal, do not continue—get professional help/recovery.

Do not do these things

  • Do not “test” the brakes with a hard stop or sharp turn on wet/icy ground.
  • Do not carry on at normal speed just because the car still moves—poor conditions reduce your margin for error.
  • Do not switch off safety systems out of frustration unless your vehicle handbook specifically tells you to for a very specific situation.
  • Do not crawl along in a live lane to inspect the car.
  • Do not place a warning triangle on a motorway or other high-speed road.

What to do now

  1. Make your stop as safe as possible. Hazards on. If it’s dark or visibility is poor, use your sidelights so you’re easier to see.
  2. If you’re on a motorway or high-speed road, follow breakdown safety priorities first.
    • If you can, leave at the next exit or stop at a service area/emergency area rather than staying on the hard shoulder.
    • If it’s not safe to exit the vehicle or reach a place of safety, stay in the car with your seat belt on and hazards on, and call 999.
    • If you’re safe and need assistance, use an emergency roadside phone (where provided) or call National Highways on 0300 123 5000 and/or contact your breakdown provider.
  3. Check exactly what is lit up. Note whether it’s:
    • ABS/traction/stability (usually amber), and/or
    • a brake system warning (often red), plus any “STOP” message.
  4. Decide “do not drive” vs “move only to safety.”
    • Do not drive; arrange recovery if any of these apply: red brake warning, “STOP” message, brake pedal feels wrong (soft/sinks), braking is clearly weaker, loud grinding, burning smell/smoke, visible fluid leak, or you do not feel safe re-joining traffic in these conditions.
    • If it’s only ABS/traction/stability (amber) and braking feels normal, you may be able to move only to a safer place/garage at low speed and with extra caution.
  5. Do one calm restart (once). With the car fully stopped in a safe place, switch off, wait a few seconds, then restart. If the warning returns, treat it as ongoing.
  6. If you must move off, drive as if assistance systems are unavailable.
    • Increase following distance a lot; avoid sudden braking/steering/acceleration.
    • Brake smoothly and progressively. If you feel the car sliding or wheels locking, ease off slightly and reapply smoothly—prioritise slowing early over last-second braking.
  7. Capture details now while you’re calm. Take a quick photo of the warning lights/messages and note the conditions (rain/ice, standing water, slush). This helps a garage recover the right context.

What can wait

  • You do not need to diagnose the fault on the roadside.
  • You do not need to keep restarting to “clear it”; one restart is enough for a quick check.
  • You do not need to decide repairs or costs now—first priority is a safe location and safe next move.

Important reassurance

It’s normal to feel a jolt of panic when brake or stability lights appear—especially in poor weather. Many ABS/traction warnings mean the extra assistance may be unavailable, not that you have no brakes at all—but in rain/ice that difference matters, and slowing the situation down is the right call.

Scope note

These are first steps to stabilise the moment and avoid a risky decision in bad conditions. If the warning stays on or returns, the next step is usually professional inspection and/or recovery.

Important note

This is general safety information, not vehicle-specific mechanical advice. Dashboard symbols and severity differ by make/model; if anything suggests reduced braking or you’re in an unsafe roadside position, prioritise emergency help or professional recovery.
