You may cross a double solid yellow line:
- To pass a slow moving truck
- To turn into a driveway ✓
- To pass a car if traffic permits
- Under no conditions
Answer: B. To turn into a driveway
You may cross a double solid yellow line to turn into a driveway.
Why this is the answer
The manual says double solid lines mean you cannot pass or change lanes, and you cannot go across them except to make a left turn to enter or leave the highway, such as to or from a driveway. Passing a slow truck or another car is not one of the listed exceptions, and saying crossing is never allowed ignores the driveway exception.
Why the other answers are wrong
- A. To pass a slow moving truck — Passing a slow-moving truck is not allowed across a double solid line, because the manual bars passing and changing lanes there.
- C. To pass a car if traffic permits — Passing a car when traffic permits is still passing, which the double solid line rule does not allow.
- D. Under no conditions — Crossing is not banned under all conditions, since the manual allows it for a left turn to enter or leave the highway, such as a driveway.
Remember it
Think of double solid yellow as no passing and no lane changes, with a narrow opening for a left turn into a driveway.
