I didn’t know this until today: According to California’s vehicle code, bicycles are not vehicles, at least when it comes to certain sections of the code.
That caused me to make a mistake in a previous blog when I said flashing lights are not technically legal on bicycles. I went back and fixed that comment, but it’s important to call it out here since it has major implications.
Here’s what VC Section 670 says: A “vehicle” is a device by which any person or property may be propelled, moved, or drawn upon a highway, excepting a device moved exclusively by human power or used exclusively upon stationary rails or tracks.
Flashing lights are only allowed on emergency vehicles, but since a bike is not a vehicle, they’re OK to use.
My only objection to flashing lights is front lights that emit a blinding white flash. You want to be seen, not be a visual distraction that blinds drivers.
