Driver's License Test Prep
California Practice Emergencies

You must stop because of vehicle trouble, but your vehicle has no emergency flashers. What does the manual tell you to use instead?

  1. A.
    Your high beam headlights
  2. B.
    Your interior dome light
  3. C.
    Your turn signals Correct
The Why

The answer is "Your turn signals"

The manual says to use your turn signals when your vehicle has no emergency flashers during a breakdown stop. High beams are for seeing and being seen while driving. Choice A carries over the habit of flashing brights at oncoming traffic to get noticed, treating a moving-driver attention tool as a stationary breakdown warning.

Why the others miss

The traps in the wrong answers

A. Your high beam headlights

The manual does not list high beams for a stationary warning; it names turn signals as the substitute when flashers are unavailable. This answer carries over the nighttime habit of flashing brights at oncoming drivers to get their attention, treating a moving-vehicle signal as a stationary breakdown warning.

B. Your interior dome light

An interior dome light faces inward and is not visible enough from behind to warn approaching drivers. This answer reaches for the first switchable light inside the cabin, missing that the manual points to an outward-facing signal already built into the rear of the car.
