As a safe and experienced motor vehicle operator, you can avoid many accidents using direction signals, as well as to warn other drivers using direction signals. It is not possible for other drivers to anticipate your actions without proper communication. It can mean the intention of turning, changing the lane, or merging. According to regulations in some countries, when driving in the city, you must signal your intention of turning, not less than a hundred feet before turning.
So, the flashing of directional signals as an indication to other vehicles is required by law at all times.
