Step-by-step explanation:
The question pertains to the specific traffic laws related to the use of turn signals. Turn signals must be activated a minimum of specific feet before making a turn to alert other road users of your intention to change direction. While the actual distance can vary by jurisdiction, a common requirement is activating the turn signal at least 100 feet before turning in residential or urban areas. For highways or faster roads, this distance may increase. It's crucial to consult your local traffic laws for the exact requirements, which can be found in the driver's handbook or through the local department of motor vehicles.
