What is the Rule About White Lines and Yellow Lines on the Road?
When driving, you often see white lines and yellow lines painted on the road. But do you know the exact rules behind them? Whether you are already a driver or planning to buy a vehicle, understanding road markings is essential for your safety. Today, MotorGuide explains the rules for white and yellow lines and how they guide your driving.
Types of Road Lines
On Sri Lankan roads, white and yellow lines are generally classified as:
- Broken white lines
- Continuous (solid) white lines
- Broken yellow lines
- Continuous (solid) yellow lines
- Broken and continuous white lines together
- Double continuous yellow lines
Broken White Lines
Broken white lines mean you are allowed to change lanes, overtake, or make a U-turn. However, always ensure it is safe before doing so.
Solid White Lines
A solid white line indicates no overtaking or U-turns. You must continue straight in your lane. These lines often mark the right edge of the road or separate lanes of traffic moving in the same direction. The only exception is in an emergency, where you may cross the solid line to avoid an accident.
Broken Yellow Lines
When you see a broken yellow line, you are allowed to overtake and make U-turns. But this is permitted only if the road is clear and safe to do so.
Solid Yellow Lines
A solid yellow line means you can overtake, but only on your side of the road. You are not allowed to cross over into the opposite lane.
Broken and Solid White Lines Together
If one side of the road has a solid white line and the other side has a broken white line, then:
- The side with the broken white line is permitted to overtake.
- The side with the solid white line is not allowed to overtake.
Double Continuous Yellow Lines
Double solid yellow lines are the strictest markings. They mean it is completely forbidden to:
- Overtake
- Make a U-turn
- Change lanes
Road markings are designed to ensure safety and discipline on the road. White and yellow lines are not just paint—they are legal guidelines you must follow. The next time you drive, pay close attention to these lines to protect yourself and others.
