This practice test focuses on real-life road scenarios you might face during the DMV written or behind-the-wheel test.
You’ll be asked not just what a sign means, but how to respond — for example, when construction narrows the lane or when a “ROAD CLOSED AHEAD” sign appears.

Each question includes explanations and memory tips based on the California Driver Handbook 2026, helping you understand both the meaning and the action required.

Frequently Asked Questions about California DMV Road Signs Practice Test 1
1. What should you do if another lane will merge into yours ahead?
You should check your mirrors, adjust your speed, and merge safely, allowing traffic from the other lane to join without abrupt braking or swerving.
2. What action is required when you see a “No Turn on Red” sign at an intersection?
You must wait for the green light before turning; you cannot turn right (or left if the sign applies) on red, even if the intersection appears clear.
3. Why must you immediately stop and turn around when you drive past a “Wrong Way” sign?
The “Wrong Way” sign means you are traveling against traffic. Continuing could lead to a head-on collision. Pull over safely and turn around as soon as possible.
4. How should you respond when the sign says “Lane Ends Merge Left” in a work zone?
You should prepare to merge left safely: signal early, check mirrors, match the speed of the left lane traffic, and avoid cutting off other drivers.
5. In a steep mountain area, what does the sign “Yield to Uphill Traffic” indicate?
On narrow, steep roads, the sign means that downhill drivers must yield and allow uphill traffic to proceed, because stopping uphill loses more momentum.
6. What should you do when you spot a “Truck Downhill / 9% Grade” warning sign?
Slow down, shift to a lower gear if necessary, and be prepared for the steep descent ahead. Control your speed rather than brake hard on the slope.
