California lane markings show how traffic is organized and where certain movements are allowed. Start with color, then look at the line pattern and any signs. A marking may allow a movement, but you still need to check that it is legal and safe.
The summaries below follow the current California Driver’s Handbook section on navigating the roads. Check the handbook for the full rule and any exceptions.

| Marking | Meaning |
|---|---|
| Broken yellow line | Passing may be allowed when the broken line is next to your lane, passing is legal, and it is safe. |
| Single solid yellow line | Marks the center of a two-way road. Do not pass when there is one lane in your direction and the solid line is on your side. |
| Double solid yellow lines | Do not pass over them or drive to their left, subject to the handbook’s limited exceptions. |
| Broken white line | Separates lanes moving in the same direction; change lanes only when legal and safe. |
| Single solid white line | Marks lanes moving in the same direction. Follow lane-control signs and markings before changing lanes. |
| Double solid white lines | Mark a lane barrier. Do not change lanes across them; wait for a single broken white line. |
| Center left-turn lane | Use to prepare for and make a left turn or permitted U-turn; it is not a regular travel or passing lane. |
| Large broken lane-ending lines | Indicate a lane may be ending; look for signs and prepare to merge or exit. |
CHECK WHAT YOU KNOW
Think You Know the Lane-Marking Rules?
Knowing yellow from white is a good start. The harder question is whether you can recognize the other California rules you still need to review.

Yellow lines separate opposing traffic
Yellow lines normally mark the center of a road carrying traffic in opposite directions. The pattern and the line next to your lane matter.
Broken yellow line
You may pass when the broken yellow line is next to your lane, passing is otherwise legal, and you have enough visibility and space to complete the maneuver safely. The broken line does not mean the road ahead is clear.
Single solid yellow line
A single solid yellow line marks the center of a two-way road. The California Driver’s Handbook says not to pass a vehicle ahead when there is only one lane of traffic going your direction and a solid yellow line is on your side. Check the road layout and signs rather than treating every yellow marking as the same rule.
Double solid yellow lines
Do not pass over double solid yellow lines or drive to their left. The handbook lists limited exceptions, including when directed around a road closure and when crossing a single set to turn left into or out of a driveway or private road, or to make a permitted U-turn. Those exceptions allow specific turns; they do not allow passing.
Two sets of double solid yellow lines spaced two or more feet apart form a barrier. Do not drive on or over it, turn across it, or make a U-turn across it except at a designated opening.
White lines separate same-direction traffic
White lines mark lanes moving in the same direction. You will see them on one-way streets, multilane roads, and freeways.
Broken white line
A broken white line separates lanes traveling in the same direction. You may change lanes when the movement is legal and safe. Signal, check mirrors and blind spots, and make sure there is enough space before moving.
Single solid white line
A single solid white line also marks lanes moving in the same direction. Do not confuse it with a double solid white line, which marks a lane barrier. Follow signs and lane-control instructions, and make a lane change only where permitted and safe.
Double solid white lines
Double solid white lines mark a barrier between lanes, including between some regular-use and preferential-use lanes such as HOV lanes. Do not change lanes across them. Wait until the lines become a single broken white line or reach a designated opening.
Center left-turn lanes
A center left-turn lane is in the middle of a two-way street. The inner line is broken and the outer line is solid. Use it to prepare for and make a left turn or permitted U-turn; it is not a travel or passing lane. You may drive in it for no more than 200 feet. Enter within 200 feet of your turn, check for other vehicles using the lane, and turn only when safe.
For the steps and exceptions, see California turn and U-turn rules.
Lane endings, arrows, and stop lines
Large broken lines may show that a freeway or street lane is ending. Look for signs that tell you whether to merge or exit, and make a safe decision early. If you miss an exit, continue safely and reroute instead of making a sudden move.
Painted arrows show which movements are assigned to a lane. Follow the arrow and posted signs; do not make a last-second turn from a lane marked for another movement. For related California rules, see the guides to traffic lights and signals and road signs.
A wide white limit line shows where to stop when a sign or signal requires it. A row of white triangles is a yield line; the triangles point toward approaching traffic. These markings tell you where to stop or yield, rather than which lane to use.
Quick practice
Can you pass next to a broken yellow line?
Only when passing is legal and there is enough room and visibility to do it safely.
What if a solid yellow line is next to your lane?
On a two-way road with one lane in your direction, do not pass when the solid yellow line is on your side.
Can you change lanes across double solid white lines?
No. Wait until the lane markings allow the movement.
How far may you travel in a center left-turn lane?
No more than 200 feet, and only to prepare for and make a left turn or permitted U-turn.

Remember: identify the color, identify the pattern, and check which marking is next to your vehicle. Then follow the applicable rule, posted signs, and safe-driving conditions.
CALIFORNIA DMV STUDY SYSTEM
Need More Than One Topic Review?
Lane markings are only one part of the California knowledge test. If practice questions reveal gaps in right-of-way, signs, parking, lane use, traffic signals, or other California rules, a broader study system may be more efficient than reviewing topics one at a time.
The California Driver Study System includes:
- 250 practice questions.
- 5 full-length practice tests.
- 250 digital flashcards.
- Rule explanations and focused review.
- A structured study system to help organize your preparation.
