What must a car do in order to join traffic?
A)Signal the manoeuvre because others must give way.
B)Always follow the instructions of another person.
C)Make sure you can do so without danger to other road users.Correct
Bear in mind that when a vehicle joins traffic it normally does not have right of way, for example when starting to move, when leaving a parking space, when joining another road, etc.
For this reason, you must always make sure you can do so without danger to other road users.
In addition, the manoeuvre must be signalled using the vehicle's light indicators (turn signals) or, failing that, with the arm.
