What does California's Anti Gridlock Law prohibit?

California's Anti-Gridlock Law is designed to prevent congestion and ensure the smooth flow of traffic at intersections. This law specifically prohibits drivers from entering an intersection when they do not have enough space to clear it. The intent is to avoid blocking cross traffic, which can lead to gridlock situations, especially during peak traffic hours. By ensuring that vehicles only enter intersections when they can completely exit, the law helps maintain traffic flow and minimizes delays.

The other options address different aspects of driving laws, such as stopping on highways or cell phone use, but they do not pertain to the core purpose of the Anti-Gridlock Law. Making U-turns at traffic lights is also regulated by other driving rules but is not the focus of this particular law. Understanding this prohibition is important for drivers to promote safety and efficiency on the road.
