Let's Decode Road Markings

1

What do white lines between lanes indicate?

Traffic moves in opposite directions.
Crossing between lanes is prohibited.
The edge of the roadway.
Traffic moves in the same direction. ✓ Correct

Correct answer: D. Traffic moves in the same direction.

White lane markings separate lanes of traffic moving in the same direction.

2

Double solid yellow lines in the center of the road:

May not be crossed under any circumstances.
May not be crossed to pass. ✓ Correct
May be crossed to pass if no oncoming traffic.
Separate same-direction traffic.

Correct answer: B. May not be crossed to pass.

Double solid yellow lines are not to be crossed for passing, because they are used to separate traffic moving in opposite directions and to reduce the risk of head-on collisions.

3

Double solid yellow lines may be crossed:

Under no circumstances.
Only for a left turn or U-turn. ✓ Correct
Only for a right turn.
Only when no oncoming traffic is visible.

Correct answer: B. Only for a left turn or U-turn.

You may cross these lines to enter/exit a driveway, a private road, or to make a legal U-turn. These lines primarily prohibit crossing into opposing traffic to pass other vehicles.

4

Under what circumstances are you permitted to cross a broken line?

When it is safe to do so and not prohibited by signs. ✓ Correct
Only if you are passing another vehicle.
Only when the line is white.
Only if the line is on your right side.

Correct answer: A. When it is safe to do so and not prohibited by signs.

A broken line indicates that crossing is generally permitted, provided that the maneuver can be done safely and there are no regulatory signs (such as "No Turn" or "Right Turn Only" signs) that forbid the action.

5

Drivers may pass when there is a solid yellow line next to a broken yellow line only if:

Traveling next to the solid line.
Traveling in either direction.
Driving a large vehicle.
Traveling next to the broken line. ✓ Correct

Correct answer: D. Traveling next to the broken line.

You may cross to pass if the broken line is on your side. This marking indicates that visibility is sufficient for passing from your direction while restricting it for oncoming traffic.

6

Crossing two sets of double solid yellow lines to overtake a vehicle may be allowed:

Under no circumstances. ✓ Correct
If the vehicle is travelling at 15mph.
If the vehicle is flashing hazard lights.
If the vehicle has a tire blowout.

Correct answer: A. Under no circumstances.

The law treats these parallel lines as a solid barrier. Passing is strictly forbidden. These markings indicate a permanent physical barrier meant to separate traffic flow. Attempting to pass here is a significant traffic violation and highly dangerous.

7

When are you allowed to cross two sets of solid double yellow lines that are spaced apart?

Only at designated openings where turns are permitted. ✓ Correct
Whenever you need to make a U-turn.
Only when no traffic is coming.

Correct answer: A. Only at designated openings where turns are permitted.

Spaced double yellow lines are legally a barrier. Crossing is forbidden except at designated openings. You cannot drive over or on this "island" for any reason.

8

A single broken white center line on a two-lane road indicates:

Same-direction traffic, lane changes discouraged.
Same-direction traffic, passing permitted when safe. ✓ Correct
Opposite-direction traffic, passing permitted when safe.
The edge of the roadway.

Correct answer: B. Same-direction traffic, passing permitted when safe.

White lines indicate traffic moving in the same direction. Passing is not prohibited when the line is broken.

9

Double solid white lines on the road indicate:

The left lane carries opposite-direction traffic.
Crossing to change lanes is prohibited. ✓ Correct
Crossing is discouraged but allowed if necessary.
Crossing to change lanes is permitted when safe.

Correct answer: B. Crossing to change lanes is prohibited.

Double solid white lines are treated as a barrier. They separate lanes moving in the same direction, and you must not cross them.

10

The road shoulder is for:

Emergency stops or disabled vehicles. ✓ Correct
Driving if moving much slower than traffic.
Passing slower vehicles.

Correct answer: A. Emergency stops or disabled vehicles.

The road shoulder is for emergency stopping or disabled vehicles.

11

This sign means:

You must turn right at the next intersection.
Keep to the right of a divider or obstruction. ✓ Correct
Pass other vehicles only on the right.
The right lane ends ahead — merge left.

Correct answer: B. Keep to the right of a divider or obstruction.

This sign instructs drivers to stay to the right of a median, traffic island, or road obstruction. It is common at the start of divided highways or near bridge supports.

12

What does this sign warn about?

Keep right to avoid oncoming traffic.
A divider is ahead. ✓ Correct
The divided highway is ending.
The road ahead becomes one-way.

Correct answer: B. A divider is ahead.

The wedge at the top signifies "Divided Highway Begins." A physical median is starting, separating traffic into two distinct one-way roadways ahead.

13

What does this sign warn about?

A divider is ahead.
All traffic shifts to the left lane ahead.
The divided highway ends and opposing traffic will no longer be separated. ✓ Correct
The road narrows ahead.

Correct answer: C. The divided highway ends and opposing traffic will no longer be separated.

The bottom wedge means the barrier is ending. Prepare for two-way traffic where oncoming vehicles are no longer separated by a median.

14

You may cross double yellow lines to pass only if:

One of the lines is broken.
The line on your side is solid.
The line on your side is broken. ✓ Correct

Correct answer: C. The line on your side is broken.

You may cross the line to pass only when one of the lines is broken and the broken line is on your side. Even then, you may pass only when it is safe.

15

When the broken line of a double yellow centerline is on your side:

Passing is not prohibited. ✓ Correct
Passing is prohibited.
Only U-turns are allowed there.
Passing is permitted from both directions.

Correct answer: A. Passing is not prohibited.

The solid-and-broken line pattern is used to prohibit passing in one direction and allow it in the other, because drivers on the permitted side have enough visibility to pass safely. The purpose of the broken line is to permit passing from that side. So, passing from the broken-line side is allowed if it is safe to do so.

16

When the lanes on a two-lane road are separated by double solid yellow lines, what does it mean?

You may pass the vehicle ahead on the left.
Passing is prohibited in both directions. ✓ Correct
You may pass the vehicle ahead on the right.

Correct answer: B. Passing is prohibited in both directions.

On a two-lane road with one lane in each direction, passing on the left would require entering the oncoming lane, which is prohibited by the double solid yellow lines. Passing on the right would usually mean driving on the shoulder, which is also prohibited.

17

On a road with no lane markings, the left lane may be used:

Only when passing or overtaking. ✓ Correct
Anytime, since there are no markings.
When the road fits two vehicles side by side.
To get a better view of the road ahead.

Correct answer: A. Only when passing or overtaking.

On a road with no lane markings, the left side should only be used when passing or overtaking another vehicle. Using the left lane freely, assuming width permits side-by-side travel, or seeking a better view are not valid reasons to occupy the left side, as it exposes you to oncoming traffic unnecessarily.

18

When the road is marked with a solid yellow line and a broken yellow line on your side you may pass:

Only in an emergency.
If you are on an expressway.
If traffic is clear. ✓ Correct
Only at an intersection.

Correct answer: C. If traffic is clear.

A broken line on your side is the signal that you are in a legal passing zone. However, the line only gives you the permission to pass; it does not guarantee it is safe. You must ensure that traffic is clear, you have enough "gap" to complete the maneuver, and you can return to your lane without cutting off the vehicle you are passing.

19

You may cross a double solid yellow line:

To pass a slow-moving truck.
To turn into a driveway. ✓ Correct
To pass a car if traffic permits.
Under no conditions.

Correct answer: B. To turn into a driveway.

This is the correct answer. You are legally permitted to cross double solid yellow lines to turn left into or out of a driveway, private road, or an alley. While you cannot use the lines to pass another car, you can use them to leave or enter the highway.

20

You may not cross a single broken white (or yellow) line:

When to do so would interfere with traffic. ✓ Correct
When turning left into a driveway.
When the car in front is disabled.
When passing to the right on a one-way street.

Correct answer: A. When to do so would interfere with traffic.

You can cross these lines to pass other vehicles or change lanes only if you can do so safely. If your maneuver forces another driver to brake, swerve, or adjust their speed, you have "interfered with traffic," making the crossing illegal regardless of the line type.

21

You may cross a single solid white line in the highway:

Whenever you want to
If traffic conditions require ✓ Correct
Only to turn into a driveway
Only to make a U-turn

Correct answer: B. If traffic conditions require

A single solid white line is used to discourage lane changes in areas where they might be dangerous (such as near intersections, tunnels, or highway interchanges). However, it is not legally "prohibited" like a double solid line. You may cross it if traffic conditions make it necessary—for example, to avoid a hazard, to exit the highway, or when a lane is merging.
