When approaching a vehicle with a flashing blue light and a special audible signal, drivers of public vehicles should:
They will continue the traffic, as they are traveling on the defined route.
Give way to ensure the unimpeded passage of the mentioned vehicle.✓Bonne réponse
Reduce the speed and give way to ensure the smooth passage of the mentioned vehicle.
Explication
A blue flashing beacon used together with the special audible signal claims priority for the responding vehicle, so public-transport drivers must clear its path. Continuing because of a scheduled route is unlawful, while an across-the-board duty to slow down belongs to the blue-and-red signal combination rather than blue alone.
