California Vehicle Code § 22108 VC: Failure to Signal Before Turning or Changing Lanes

California Vehicle Code § 22108 VC is one of the most frequently cited traffic laws in California. While often seen as a minor infraction, a violation can have immediate financial, driving record, and even criminal consequences if not handled correctly.

Below is a comprehensive guide to understanding VC § 22108, the penalties it carries, and how it impacts your driving privilege.

Legal Definition of VC § 22108

The statutory language of California Vehicle Code § 22108 VC is brief but strict:

“Any signal of intention to turn right or left shall be given continuously during the last 100 feet traveled by the vehicle before turning.”

Key Legal Elements

The 100-Foot Rule: You must activate your signal at least 100 feet before making any turn or changing lanes. A brief "flick" of the blinker right as you execute the maneuver violates this statute.
Mandatory Application: The law applies to both right and left turns, as well as highway lane changes and merging maneuvers.
Criminal Crossover (Penal Code Connections): While a VC 22108 violation itself is an infraction (not a crime), willfully failing to appear in court or pay the ticket transitions the matter into a misdemeanor under California Vehicle Code § 40508 VC. This misdemeanor is prosecuted similarly to Penal Code offenses and is punishable by up to six months in county jail and/or a fine of up to $1,000.

Penalties and Financial Impact

Violating VC § 22108 is an infraction that carries both direct and indirect penalties.

Penalty Category	Consequence / Cost	Key Details
Base Fine	$238.00	The standard fine amount for this infraction.
DMV Points	1 Point	Added to your driving record; stays active for 3 years.
Insurance Premium Increase	$750.00 (est. over 3 years)	A single DMV point often causes auto insurance rates to climb.
Negligent Operator Risk	Potential Suspension	Accumulating 4 points in 12 months (or 6 in 24, 8 in 36) results in a license suspension.

Real-World Example

The Scenario:

Sarah is driving her sedan down a multi-lane boulevard in San Jose. She spots an opening in the right lane and immediately switches lanes, tapping her turn signal just as her wheels cross the white line. A California Highway Patrol (CHP) officer pulls her over and issues a ticket.

The Verdict:

Even though Sarah technically used her turn signal, she violated VC § 22108 because she did not signal continuously for the required 100 feet prior to initiating the lane change.

Common Defenses Against a VC § 22108 Citation

While a failure-to-signal ticket may seem difficult to fight, a driver is not automatically guilty simply because an officer issued a citation. There are several legal strategies commonly used to contest a charge under Vehicle Code § 22108 VC:

The 100-Foot Distance Was Impossible: If you were parked or sitting at an intersection and immediately had to make a turn upon accelerating, it may have been physically impossible to travel a full 100 feet before executing the turn.
Officer Misjudged the Distance: Traffic officers must estimate distances visually, often from a distance or while moving. If you can establish that you activated your signal well before the turn, but the officer miscalculated the 100-foot threshold from their vantage point, you have a strong defense.
Emergency Maneuver / Necessity: If you had to make a sudden turn or lane change to avoid an immediate hazard (such as a swerving car, debris in the road, or a pedestrian stepping off the curb), you may argue the defense of "necessity." In an emergency, safety takes precedence over the 100-foot signaling rule.
The Signal Was Functional But Obstructed: If your turn signal was actively blinking but temporary road conditions, glare, or another vehicle temporarily blocked the officer's line of sight, you did not violate the statute.

How to Conduct a Trial by Written Declaration

Request the Forms: You need Form TR-205 (Request for Trial by Written Declaration). You can usually find this on your county's Superior Court website or request it from the court clerk by the due date on your ticket.
Pay the Bail: You must include a check or money order for the "bail" amount listed on your courtesy notice. Note: This is a refundable deposit. If you are found "not guilty," the court mails this money back to you.
Draft Your Statement: This is the most critical part. Your statement should be factual, concise, and professional.
- Use the Form MC-031 (Attached Declaration) if you need more space than the TR-205 provides.
- Keep it unemotional. Avoid complaining about the officer; focus solely on the elements of the law.
Gather Evidence: Include diagrams (e.g., a sketch showing the intersection/turn), photographs of the location, or even a statement from a passenger (witness) signed under penalty of perjury.
Submit via Certified Mail: Send your TR-205, your written defense, your evidence, and your bail payment via Certified Mail with a Return Receipt. This provides legal proof that the court received your documents before the deadline.

Vehicle Code § 22107 VC (Unsafe Turn/No Signal): This law prohibits turning or moving left or right on a roadway until it can be done with "reasonable safety" and only after giving an appropriate signal if other traffic could be affected.
Vehicle Code § 21658 VC (Unsafe Lane Changes): Mandates that drivers stay within a single lane and only move from that lane when it is safe to do so.
Vehicle Code § 40508 VC (Failure to Appear): The statute that makes ignoring your signed traffic ticket a misdemeanor criminal offense.

Frequently Asked Questions (FAQs)

Do I have to signal if there are no other cars around?

Yes. Under California Vehicle Code § 22108 VC, the duty to signal for 100 feet is an absolute requirement before any turn, regardless of whether other vehicles are nearby. This differs slightly from VC § 22107 (unsafe turning), which specifically references when other traffic may be affected.

Can failing to signal lead to a DUI stop?

Yes. Police officers frequently use a failure to signal as "reasonable suspicion" to initiate a traffic stop. Once stopped, if the officer smells alcohol or notices signs of impairment, a minor traffic infraction can quickly escalate into a full DUI investigation and arrest.

How many points will a VC 22108 violation add to my California driving record?

A violation of VC § 22108 adds one point to your California DMV public driving record. This point remains on your record for 36 months (3 years) and can raise your auto insurance premiums.

Can I go to traffic school to mask a VC 22108 ticket?

Yes. If you meet the general eligibility requirements (e.g., you have not attended traffic school for another citation in the past 18 months), you can complete traffic school. Doing so hides the DMV point from your public record, preventing your insurance company from raising your rates.

What happens if I ignore my VC 22108 citation?

Ignoring the ticket constitutes a separate misdemeanor charge under Vehicle Code § 40508 VC. A California court can issue a bench warrant for your arrest, suspend your driver's license, or add severe financial penalties.

Is a hand signal legally acceptable under California law?

Yes. California law permits hand and arm signals in place of signal lamps, provided they are executed correctly and clearly visible to other drivers. To signal a left turn, extend your hand and arm horizontally; for a right turn, extend your hand and arm upward; and to signal stopping or decreasing speed, extend your hand and arm downward.
