Final answer:
A solid yellow line on your side of the centerline means that passing is not allowed. This marking indicates that the lanes are moving in opposite directions and crossing the line could lead to head-on collisions.
Step-by-step explanation:
A solid yellow line on your side of the centerline means that passing is not allowed from your side of the road. This traffic marking is used to indicate that the lane on the other side of the centerline is moving in the opposite direction and that it would be unsafe to cross into oncoming traffic to pass a vehicle in front of you. If the solid yellow line is on the opposite side, drivers in that lane are not permitted to pass. However, if you're on a road with a solid yellow line and a broken yellow line together, you may pass only if the broken line is on your side.
