What is the difference between double white solid lines and single white solid lines?

[SanElliott]

The difference between double white solid lines and single white solid lines lies in the number of traffic lanes. Below are specific explanations of their differences: 1. Number of lanes: A single solid line or single dashed line indicates there is only one lane in the same direction, while double solid lines indicate there are two or more lanes in the same direction. 2. Purpose: The main purpose of a single solid line is to warn vehicles not to cross the line for overtaking. Roads with double yellow solid lines are generally wider. At the very least, they consist of two lanes on one side plus a white solid line separating the motor vehicle lane from the non-motor vehicle lane. The wider road makes it more difficult for drivers to distinguish lanes when turning or passing intersections. Using a single yellow line in such sections could easily lead to driving in the wrong lane, whereas double yellow lines make it much easier to differentiate.
