I pulled the actual Jargon from www.chp.ca.gov website, it is below:

Move Over/Slow Down (SB 159, Simitian) The new law removes the January 1, 2010, sunset
date on Sections 21809 VC and 25253 VC. Section 21809 VC requires a person driving a
vehicle on a freeway and approaching in a lane immediately adjacent to a stationary, authorized
emergency vehicle that displays emergency lights, or a stationary tow truck that displays flashing
amber warning lights, to safely make a lane change from that lane, or slow to a reasonable speed.
Section 25253 VC requires tow trucks used to tow disabled vehicles to be equipped with flashing
amber warning lamps and authorizes tow trucks to display flashing amber warning lamps while
providing service to a disabled vehicle. However, this section prohibits tow trucks from
displaying flashing amber warning lamps on a freeway except when an unusual traffic hazard or
extreme hazard exists.

Department of Transportation Vehicles (SB 240 Wright) Currently as section 21809 VC
(Move Over, Slow Down Law) requires a person who is driving a vehicle on a freeway and
approaching in a lane immediately adjacent to a stationary, authorized emergency vehicle that
displays emergency lights, or a stationary tow truck that displays flashing amber warning lights,
to safely make a lane change from that lane, or slow to a reasonable speed. This new law adds a
stationary, marked Caltrans vehicle displaying flashing amber warning lights to the “Move Over,
Slow Down Law.”

Be aware of your surroundings and be safe!
