Core: Traffic-jam behaviour and breakdowns: clearing space and getting yourself to safety

In a traffic jam six behaviour rules apply at once (Book p.167): you do not change lanes, you keep your distance, you leave room for motorcyclists filtering between the rows, you switch off the engine when stationary for a long time, you stay in the car, and you follow traffic information via the radio or navigation. The hazard lights follow their own timing, separate from the length of the jam: they go on the moment you unexpectedly come upon the jam, and go off again once the vehicles behind have slowed down or noticed — not for the whole jam. On the rescue corridor, the book states only the general duty: if there is no hard shoulder, you clear space for emergency services. A fixed formation (for example 'left lane goes left, the rest goes right') is not part of this teaching material — you apply the general duty to whatever situation arises, without a memorised pattern. In a breakdown on the road, the order is: as far right as possible, preferably the verge; exit on the right; put on the safety vest; wait behind the crash barrier; and call roadside assistance with your location using the hectometre marker — the small sign with distance and road number along the hard shoulder.
