Centerline and barrier line

The center line separates traffic traveling in opposite directions. The type of line determines whether you are allowed to cross it to overtake.

Types of center lines

When does a solid line apply?

Solid line means you cannot overtake other vehicles by crossing the line. This applies even if you think visibility is good. The line is there because the road authorities have determined that the section is unsuitable for overtaking.

You may still cross a solid line to:

• Turn onto a property or side road on the left side
• Pass an obstacle blocking your lane (with great caution)

Combined line – who can cross?

A combined line has a solid and a dashed line next to each other. The rule is simple:

• If you are driving closest to the dashed line, you can cross.
• If you are driving closest to the solid line, you cannot cross.

Warning line vs. dashed center line

The warning line has longer dashes and shorter gaps than a regular dashed center line. It warns that a solid line is coming, or that visibility will soon be poor. You should not start overtaking on a warning line unless you are sure you can get back in time.

Common pitfalls

• Believing that a solid line can be crossed when it “looks safe” – it is always prohibited.
• Confusing a warning line with a normal dashed line.
• Forgetting that a combined line has different rules for each side.
