At the beginning of the video, your car is parked. Do you have an obligation to signal using your direction indicators before you drive?
“When a driver intends to start from one side of the road [...] the driver shall give a signal using the direction indicators in order to signal their intention [...] Signals shall be given in good time before the intended manoeuvre is executed and shall be clearly visible and unambiguous. The giving of the signal shall end as soon as the manoeuvre is completed.” (Road Traffic Ordinance)
Because you are pulling out to the left, you must use your left-hand direction indicators.
There is also a driving licence book online (2023).
