You are following a slow maintenance truck on a two-way road. A broken yellow stripe runs next to your lane; beside the opposing lane the paired stripe is solid. Which check is essential before deciding to pass?

Confirm the broken stripe is beside your lane and that you can see enough road to complete the pass safely. (correct): Correct. Both the side of the marking and the safety of the full maneuver matter.
Confirm only that the opposing lane looks empty at the moment you start moving left.: Not enough. A momentary gap is not a substitute for being able to see and complete the full pass safely.
A broken stripe beside your lane means the pass is allowed even if you cannot see beyond the rise ahead.: Incorrect. The broken stripe does not remove the need for a clear view and safe space.

This paired center marking gives passing permission to traffic on the broken-line side, not the solid-line side. That marking rule does not replace the driver’s separate judgment about sight distance, approaching traffic, and room to return.

You are approaching a freeway and decide to join a carpool lane. Two solid white stripes separate it from your lane. Where should you make the lane change?

Signal and cross the pair if the HOV lane is empty.: Incorrect. A clear lane and a signal do not authorize crossing this lane divider.
Remain in your lane until the separator reaches an authorized crossing place, then move over only if the change is safe and signs permit it. (correct): Correct. Wait for a permitted crossing place and make the move only when safe.
Drive on the stripes briefly and enter the exit lane at its taper.: Incorrect. Riding on the separator does not create a permitted lane change.

For ordinary HOV access, DMV and CHP guidance call for a designated crossing place or a single dashed white marking. Missing an exit does not remove that restriction; once a permitted crossing is available, the lane change still has to be safe.

You are driving eastbound on a divided boulevard and need to reverse direction. Its median shows four solid yellow stripes arranged as two pairs, with about 30 inches of pavement separating the pairs. A signed U-turn opening lies ahead. What should you do?

Make the U-turn now by crossing the painted median where you are.: Incorrect. A clear-looking spot in the painted barrier is not the designated opening.
Stay on the eastbound roadway until the signed opening, then turn into the westbound roadway when permitted and safe. (correct): Correct. Continue in the correct-direction roadway to the designated opening; complete the U-turn only when signs permit and the movement is safe.
Drive onto the painted separator and follow it to the signed opening.: Incorrect. The painted median is a barrier, not a route for driving along it.

The separation described is greater than two feet, which California DMV identifies as a barrier arrangement. Stay on the eastbound roadway until the designated opening lets you make the U-turn into the westbound roadway, if signs permit and the movement is safe. The painted separator is not a travel lane.

You are leaving an access road on the south side of an east-west two-way street. Your car faces north. You want to turn left and travel west. The road has one pair of solid yellow lines at its center. Which path is correct when a safe gap is available?

Cross the eastbound lane and the single center-line pair as part of the left turn, then enter the westbound lane. (correct): Correct. This path crosses the single center pair to reach the lane carrying traffic in the direction the driver intends to travel, after checking for a safe opening.
Turn into the eastbound lane first, then cross the center-line pair farther along to reach westbound traffic.: Incorrect. Entering an eastbound lane to travel west would put the vehicle in opposing-direction traffic; make the intended turn into the westbound lane.
Pull onto the center-line pair and wait there for westbound traffic to clear.: Incorrect. The painted center marking is not a place to wait or travel. Wait on the access road until the full turn can be made safely.

For the described left turn from an access road, the intended destination is the westbound lane beyond the center marking. California DMV guidance permits crossing one center pair as part of a safe left turn into or out of an access. The exception does not allow a driver to travel along the center marking or use the opposing lane to overtake.

# California lane-marking decisions to practice

A short supplementary set for adult noncommercial California Class C learners. These are original questions and explanations, not official DMV test questions.

## 1. Broken and solid yellow at the road center

On a two-way road with one broken and one solid yellow stripe, the side next to the broken stripe is the side from which a driver may cross to pass. The driver must still be able to see far enough and complete the maneuver safely. The solid side does not gain permission from the other side’s broken stripe.

**Check:** identify the stripe beside your lane, then judge the whole pass.

## 2. Two continuous white stripes between lanes

A double-solid-white lane divider marks a place where lane crossing is prohibited. For a normal carpool-lane entry or exit, wait until the roadway provides an authorized crossing place or a single dashed white divider. Make the change only when signs permit and traffic conditions are safe.

**Check:** an open adjacent lane or turn signal does not create a crossing point.

## 3. A wide painted yellow median

Two solid double-yellow pairs with at least two feet between the pairs form a painted barrier under DMV guidance. Stay in your proper roadway direction and use an opening that is designated for your turn or U-turn. Do not drive along the painted separator.

**Check:** a gap in traffic is not the same as an authorized opening.

## 4. Left turn from an access onto a two-way road

California DMV guidance allows a driver to cross one center pair as part of a safe left turn into or out of a driveway or private access. The turn must end in the lane traveling in the driver’s intended direction. This allowance does not let a driver travel along the center marking or overtake in the opposing lane.

**Check:** trace the path to the correct-direction lane before moving.
