Driver's License Test Prep
California Practice Sharing the Road

Along with emergency vehicles, which stopped vehicle triggers the Move Over and Slow Down law?

  1. A.
    A tow truck driving past you with amber warning lights on
  2. B.
    A parked passenger car with no warning lights displayed
  3. C.
    A stopped tow truck displaying flashing amber warning lights Correct
The Why

The answer is "A stopped tow truck displaying flashing amber warning lights"

The manual pairs stationary emergency vehicles with tow trucks displaying flashing amber warning lights, and adds stopped road work vehicles with emergency or amber warning lights, as the covered categories. Choice A tempts drivers who read amber warning lights as the whole trigger and forget the manual attaches the duty to a stationary tow truck, not one moving through traffic.

Why the others miss

The traps in the wrong answers

A. A tow truck driving past you with amber warning lights on

A tow truck moving past in traffic is not stationary, so it sits outside the rule's coverage of stopped emergency, tow, and road work vehicles. This answer reads amber warning lights alone as the trigger, missing that the manual attaches the duty to a stationary tow truck rather than one in motion.

B. A parked passenger car with no warning lights displayed

A parked passenger car with no warning lights is not one of the emergency, tow, or road work vehicle categories the law covers. This answer treats any vehicle stopped on the shoulder as a Move Over trigger, generalizing past the emergency, tow, and road work categories the rule names.
