How should you react if you see this signal?
Don’t panic, but don’t be indifferent either. Here are the right steps to take:
– Slow down gradually, without braking suddenly so as not to surprise the drivers behind you. – Yield only if it is safe and doesn’t require you to break any rules. – If the vehicle is stopped, assess whether you can stop safely, with your hazard lights on, to offer assistance. – Call emergency services — 15, 17, or 18 — if the situation seems serious. This is often the best help you can provide. – Remain calm if you encounter a driver who seems agitated or unpredictable.
Roadside solidarity, yes — but with caution. Helping someone in difficulty is a noble human instinct. But this solidarity should never endanger your safety or that of other road users. Calling emergency services is often the most useful and safest course of action.
This informal signal persists because it fills a void: hazard lights indicate a stop, but don’t explain why. In this gap, drivers have created their own language.
Knowing this code means driving with a little more empathy—and sometimes, it makes all the difference.
