At first glance, it might seem unnecessary to signal when you are already positioned in a turn lane. However, in states such as California, failing to do so could lead to a citation.

The California DMV’s Driver’s Handbook outlines specific actions drivers must undertake prior to executing a left or right turn. These include moving into a designated turn lane, being vigilant for pedestrians and cyclists, and activating a turn signal approximately 100 feet before the turn—typically before stopping at the limit line.

Although not explicitly mentioned, the handbook’s description implies the necessity of signaling in a turn lane. This is further reinforced by California Code, VEH 22108, declaring: “Any signal of intention to turn right or left shall be given continuously during the last 100 feet traveled by the vehicle before turning.” There are no exceptions noted.

General Turn Signal Requirements Across the U.S.

California is not unique in its requirement to signal while in a turn lane; this is a widespread traffic regulation across the United States.

For instance, Florida Statute 316.155 mandates that drivers use their turn signals whenever turning, activating them 100 feet before the maneuver. Similarly, Massachusetts General Laws Chapter 90, Section 14B requires drivers to signal “before making any turning movement.” Nebraska Statute 60-6,161 also instructs that turn signals must be employed 100 feet ahead of any turn.

Though it may appear obvious to some drivers, this regulation is crucial for maintaining safety on the roads. A turn lane alone does not communicate your intentions to other drivers, even if it can be inferred. A turn signal enhances clarity regarding your plans, fostering better communication among all road users, including other motorists and pedestrians.

Moreover, ignoring this rule can lead to fines; for example, violating California Code 22108 may result in a $238 fine. To avoid penalties, it is advisable to adhere to standard turn signal practices, whether navigating through a designated turn lane or a roundabout.
