- Passing is allowed in both directions
- Passing is prohibited in both directions (Correct answer)
- The road is one-way

Double solid yellow center lines mean no passing is permitted in either direction.
Question 2: A triangular sign with the point facing downward and the word 'YIELD' means:
- Stop completely before proceeding
- Give the right-of-way to crossing traffic (Correct answer)
- Merge into traffic when safe
- Slow to 15 mph
Correct answer: Give the right-of-way to crossing traffic
A yield sign requires you to slow down and give the right-of-way to vehicles and pedestrians in the intersection.

- Yield before turning in the indicated direction
- You may turn in the arrow's direction without yielding to oncoming traffic (Correct answer)
- Pedestrians have the right-of-way
- Speed up to clear the intersection
Correct answer: You may turn in the arrow's direction without yielding to oncoming traffic
A steady green arrow is a protected turn signal, meaning conflicting traffic is stopped and you may proceed without yielding.
