What does a solid white line on the road indicate?

A solid white line on the road signifies that you should not change lanes or cross it. This type of line is often used to indicate that lane changes could be dangerous or that the lane is specifically designated for certain types of traffic. It serves as a guide to keep vehicles in their respective lanes and to maintain safe driving conditions.

In contrast to dashed lines, which indicate that lane changes are permitted, a solid white line reinforces the importance of staying in your lane. This is particularly crucial in areas where visibility might be limited or where there are conditions that could lead to accidents if drivers were to change lanes. Understanding the implications of road markings, such as solid white lines, is essential for maintaining road safety and adhering to traffic laws.
