What type of lines are used to separate lanes of traffic going in the same direction and designate special use lanes?

The type of lines that are used to separate lanes of traffic going in the same direction and designate special use lanes are double solid white lines. These lines indicate that lane changes are not permitted, ensuring that drivers stay within their designated lanes. This is particularly important for special use lanes, like those designated for carpooling or for buses, where maintaining lane integrity is critical for safety and efficient traffic flow.

In contrast, broken white lines are used to indicate that lane changes are allowed, while solid yellow lines separate traffic moving in opposite directions. Dotted yellow lines, typically found in areas where passing is permitted, also do not serve the same purpose as double solid white lines. The clarity provided by double solid white lines helps reinforce safe driving practices and traffic regulations.
