assess the traffic conditions yourself and make sure that any maneuver is safe and permitted.
A Small Gesture That Can Make Overtaking Easier
The next time a truck briefly flashes its headlights after you have overtaken it, there may be no reason to assume that the driver is irritated. In some situations, the flash is simply a practical way of indicating that your vehicle or vehicle combination has completely passed the truck.
It is a small gesture of communication between road users that can make it easier to judge the position of a long vehicle combination. Nevertheless, safe lane changes should always depend on your own observation of the road, mirrors, traffic conditions, and applicable traffic rules—not solely on another driver’s signal.
