Final answer:
Double solid center yellow lines indicate that no vehicle is allowed to pass or overtake other vehicles in either direction on the road.
Step-by-step explanation:
If you see double solid center yellow lines on your way, it means that passing or overtaking other vehicles in either direction is prohibited. These lines are typically found on roads where there are higher risks associated with passing, such as on curves or hills where you cannot see far enough ahead to pass safely. You must follow the road as it bends and turns, ensuring you travel the two-dimensional, zigzagged paths dictated by the layout of the streets, similar to the movement of walkers and drivers in a densely populated city like New York as described in the reference material.
