Blinking Red Light: What Drivers Must Do
A flashing signal is still an instruction, not an invitation to improvise because the usual sequence is absent. In this California question, flashing red is handled like a stop sign. Separate two decisions: bringing the vehicle to a complete stop, then deciding whether the intended path is clear. The light does not give your approach automatic priority. The original exercise below tests that distinction, while the explanation compares a stop requirement with a caution warning and an imagined future change of light. Source
The short answer
Make a complete stop, then proceed only when it is safe under the applicable yielding rules.

Why this answer fits the situation
The correct response contains both parts of the instruction. Stopping alone does not establish that a pedestrian, bicycle or crossing vehicle is out of your path. Conversely, checking a clear-looking intersection without stopping omits the first part. Think of the familiar STOP sequence rather than waiting for a flashing light to become an ordinary steady signal. The California handbook identifies the flashing-red response; this page does not invent a new priority rule for every unusual intersection arrangement.
How to read the decision on the road
Before moving, identify which control actually faces your approach and observe the crossing. Do not copy the vehicle ahead merely because its driver has already gone. Its timing and intended movement may differ from yours. In the practice question, read the whole answer rather than selecting a phrase simply because it contains “stop”. The useful distinction is a complete stop followed by a safe decision, not a prediction of what the light might display next.
Why the other choices do not fit
Slow and continue
Slowing and continuing substitutes the response associated with a caution warning for the complete stop required here. A quick look or an empty intersection does not make the omitted stop part of the instruction disappear.
Wait for it to become solid
Waiting for a solid indication invents a change that the question does not promise. The light is already communicating a usable instruction. Respond to that actual flashing-red instruction rather than treating it as information about a future phase.
Proceed with priority
The question supplies no priority grant for your road. After the stop, the actual conflict still has to be assessed. Stopping must not be followed by an assumption that every other road user will give way to you.
