During twilight or the hours of darkness, when must you have your side lights switched on as a minimum requirement?

Your chosen answer is correct. According to German traffic regulations, side lights must be switched on when a vehicle is parked on the hard shoulder outside built-up areas. This is crucial for visibility and safety, as it helps make the vehicle visible to other road users in low-light conditions.

Additionally, while driving on roads with adequate continuous lighting, it is not mandatory to use side lights. However, having them on is sometimes advisable for increased visibility.

Understanding these rules ensures that you comply with traffic regulations and enhance safety during twilight or nighttime driving.
