When the overtaking manoeuvre is finished, the overtaken vehicle must...
A)Continue driving the same way, with the high beam on.
B)Reduce speed, compulsorily.
C)Switch from high beam to low beam.Correct
The correct answer is to switch from high beam to low beam. When the vehicle that is overtaking has completed the manoeuvre and returns to its lane, it must switch from high beam to low beam to indicate that the manoeuvre has ended and to restore normal visibility. This is a courtesy and road safety rule that facilitates communication between drivers.
