Name the control before recalling a slogan
Start with the facts the prompt actually supplies: signs, signal, road layout, positions and intended movements. Separate supplied facts from assumptions. If arrival order or an arrow is unclear, mark it missing instead of inventing a convenient reading.
The California handbook distinguishes controls. At an uncontrolled intersection without traffic signals or STOP/YIELD signs, earlier arrival matters; on simultaneous arrival, yield to the road user on your right. At an all-way stop, stop first before applying the stated order. At an uncontrolled T intersection, users on the through road have priority. These summaries apply within their conditions, not to every junction.
Keep the source section and date beside the study note. A detached memory aid can lose the condition that made the rule relevant. Your goal is to explain that condition, not only remember an answer letter.
Worked map: change one fact, reconsider the response
These are original simplified study scenarios, not official questions or directions for a real junction. Read the complete current handbook and follow qualified instruction.
| Prompt facts | Condition | Study response | Check next |
|---|---|---|---|
| Simultaneous vehicles; uncontrolled junction, no traffic signal or STOP/YIELD | Same arrival | Yield to vehicle on right | Other users or controls? |
| Approach stem of T; no STOP/YIELD | Through road | Yield to through-road users | Any actual signs? |
| Left turn; opposing vehicle close enough to be dangerous | Conflicting turn | Yield | Pedestrians and other conflicts? |
| Green, but exit space unavailable | Blocked intersection | Do not enter and block it | Space to clear and crossing users? |
Change the first scenario by adding a traffic signal. Do not reuse the old conclusion automatically: inspect the new control. Write “condition changed; re-evaluate” before choosing the relevant passage. Keep the original and changed versions side by side.
The handbook requires checking pedestrians and bicyclists and caution on green. Apparent priority is not permission to force a collision. Keep a conflict check even when an answer seems obvious.
Test reasoning separately from reading the question
For a visual prompt, describe signs and arrows in words before answering. A mistaken reading and a misunderstood rule need different follow-up. Record which one occurred so your next study session addresses the actual error.
Change only one fact per comparison: control, arrival or intended turn. If everything changes, you cannot tell whether the original condition was understood. If the image lacks a necessary detail, return to the source or ask an instructor rather than declaring an unsupported answer certain.
Practice while parked safely or away from the road, never while driving. The page cannot inspect a live junction, evaluate a safe gap or replace traffic controls, the official handbook and instruction.
CalAce is independent practice, not DMV authority
CalAce’s current listing includes practice questions/explanations, mock tests, missed/saved-question review, topic cards and visual signs/intersection quizzes. It lists Premium for the full bank, mock tests, mistake review, handbook cards, offline study and bilingual explanations. Not every free allowance is enumerated.
We publish CalAce. It is not affiliated with, endorsed by or sponsored by California DMV and cannot guarantee an exam pass. The CSV is a separate reasoning map, not an app import or official test question reproduction.
Use the parent missed-question log for a general revision queue. This page instead helps distinguish similar scenarios by the condition that changes the reasoning. Keep the current handbook link accessible whenever an app explanation needs checking.

Questions answered
Does the vehicle on the right always go first?
No. Controls, arrival and other conditions matter; use the applicable full handbook passage.
Can I enter a blocked junction on green?
The California handbook prohibits blocking an intersection without enough space to clear it.
Is this official test material?
No. The worksheet and scenarios are independent; the linked DMV handbook is the authority.
