What Does a Flashing Red Signal Light Mean?

A flashing red signal light means you must come to a complete stop before proceeding when it is safe to do so. It serves the same purpose as a stop sign and requires drivers to yield to other vehicles and pedestrians before continuing.

According to the California Driver Handbook, drivers should:

• Stop completely at the stop line, crosswalk, or intersection.
• Look left, right, and ahead to ensure the way is clear.
• Proceed only when safe, yielding to vehicles with the right-of-way.

Flashing red lights are commonly used at intersections, railroad crossings, and in areas where additional caution is needed.

California Vehicle Code on Flashing Red Signal Lights

The California Vehicle Code (CVC) Section 21457 states that a flashing red light should be treated like a stop sign. Drivers must:

• Come to a full stop before entering the intersection.
• Yield the right-of-way to pedestrians and other vehicles already in or approaching the intersection.
• Proceed only when it is safe and legal to do so.

Failing to comply with a flashing red signal can result in traffic citations, fines, and points on your driving record.

Where You Might Encounter a Flashing Red Signal Light

Flashing red lights are strategically placed in areas where drivers need to exercise additional caution. You might encounter them in the following locations:

1. Intersections with Heavy Cross Traffic

Some intersections use flashing red lights instead of regular signals to control traffic flow while allowing for cautious progression.

Tip: Treat the flashing red light like a stop sign and yield to vehicles with the right-of-way before moving forward.

2. Railroad Crossings

A flashing red signal at railroad crossings indicates that a train is approaching. In this situation, drivers must:

• Stop at least 15 feet from the nearest rail.
• Wait until the lights stop flashing and the crossing gates fully lift before proceeding.
• Never attempt to cross while the lights are flashing.

Ignoring flashing red lights at railroad crossings is not only dangerous but also illegal under CVC Section 22451, which mandates full stops at active crossings.

3. School Zones and Pedestrian Crossings

Flashing red lights are often used near schools to signal when children are crossing. Drivers must stop completely and wait for the crossing guard to signal before proceeding.

---

4. Traffic Control During Power Outages

When regular traffic signals fail due to power outages, intersections may default to flashing red lights. In such cases, all drivers must treat the intersection as a four-way stop.

Important: When approaching these intersections, proceed cautiously and be prepared for unpredictable traffic behavior.

• Rolling Stops: Failing to come to a full stop can result in traffic tickets and accidents.
• Failing to Yield: Not yielding to vehicles or pedestrians can lead to collisions.
