Road lines guide drivers. They tell you where to drive, when to change lanes, and when overtaking is unsafe.
What White Lines Mean
- Separate lanes moving in the same direction
- Help you stay in your lane
- Show where lane changing is allowed or not
What Yellow Lines Mean
- Often separate traffic moving in opposite directions
- Warn about no overtaking areas (especially with solid lines)
- Help prevent head-on crashes
Solid vs Broken Lines
- Broken line: you may cross it if it is safe
- Solid line: do not cross (or cross only when allowed by rules)
- Double solid lines: do not cross
Safety Tip
If you are not sure, treat the line as “do not cross” and drive carefully.
Key Points
- White lines usually separate lanes in the same direction
