When is a driver required to use turn signals?

A driver is required to use turn signals when making any turn or lane change to communicate their intended actions to other road users. This signaling is crucial for maintaining safety on the road as it informs nearby drivers and pedestrians of the driver's intentions, thereby helping to prevent accidents.

Turn signals not only indicate a driver's intention to change lanes or turn but also allow others to anticipate these movements and react appropriately. This requirement applies regardless of the time of day, road conditions, or whether the driver is in a rural or urban setting. Using turn signals is fundamental to good driving practices and is a legal requirement in most jurisdictions, including Wisconsin.

Signaling before turns or lane changes contributes to the overall flow of traffic and enhances safety for everyone on the road.
