In Pakistan, often we do not care about traffic rules and road safety, and many people recognize traffic rules just about red, yellow and green light. When in reality, road safety is a serious concern in Pakistan and we all need to be well informed about traffic rules and road signs, which will certainly safeguard our drive.
If you run with full attention, you will see the white and yellow lines on the streets. The color difference is not marked as they were less than white paint so that they painted yellow instead of yellow, white, solid and broken roads. These lines are part of road signs, and need to be implemented for road safety.
Solid White Line
Solid white lines indicate that you should not change the lane and stay in the lane you are already.
Broken White Line
This means that you are allowed to change the lane, but safely and when needed.
One Solid Yellow Line
It means that overtaking is allowed if there is enough space, but you can not cross the yellow line.
