Final answer:
A double solid yellow set of lines running parallel with the road signifies a no-passing zone, indicating that drivers are not allowed to pass other vehicles in this area.
Step-by-step explanation:
A double solid yellow set of lines running parallel with the road signifies a no-passing zone. It indicates that drivers are not allowed to pass other vehicles in this area. These lines are typically found in areas where there are limited visibility or high-risk conditions, such as curves or hills.
For example, on a two-lane road with a double solid yellow line, drivers should not attempt to pass slower vehicles in front of them. They must wait for a passing zone where the lines become broken or move to a lane where passing is allowed.
