Green line on the road

What does a green line on the road mean?

Green between two white centre lines means: you may usually drive 100 km/h here. How fast may you drive with a green line? Basically 100. But the signs along the road decide.

You can expect a lower speed:

• just before a junction or a dangerous spot: there is often a 70 sign;
• at roadworks: temporary signs show a lower speed;
• when a matrix sign above the road shows a lower speed.

Memory aid: green = 100, just like the green 100-euro note. But the sign always comes before the colour. So a 70 or 80 sign still applies, even if the green continues.

Green with a solid or broken line

May you overtake at a green line? That depends on the white lines, not on the green:

Broken white lines: you may overtake when it is safe.

Solid white lines: you may not overtake. See the solid line.

One broken and one solid: you may only overtake from the side with the broken line.

Where you do (and do not) find a green line on the road

You see a green line on roads outside built-up areas where 100 km/h applies. Usually that is an autoweg. Many autowegen have an N number, such as the N34. The N number itself says nothing about the speed.

You do not see a green line:

• on the motorway: the directions are already separated there;
• inside built-up areas;
• on ordinary roads outside built-up areas where 80 km/h applies.

Green line or autoweg sign?

Whether you are on an autoweg is shown by sign G3, not by the green line. So an autoweg without green is possible too. What an autoweg is and how fast you may drive there is explained under speed on the autoweg. Which sign comes first when several speeds are shown is explained under speed signs.

Recognising different roads by their lines

What do the coloured lines on the road mean? If there is no sign, the centre line helps you know the speed. This is how you know whether you may drive 80 or 100:

What do you see?	Type of road	Speed
Two white lines, nothing in between	Ordinary road outside built-up areas	80 km/h
Green line	Usually an autoweg	100 km/h
Purple line	Road in the province of Utrecht	60 km/h, on the signs. See the purple line
No centre line	Narrow road outside built-up areas	80 km/h, 60 only with a sign

CBR exam pitfalls for the green line

❌ Wrong: Green line comes before the sign? ✅ Right: No. The sign comes first.

❌ Wrong: Green means no overtaking? ✅ Right: No. The white lines decide.

❌ Wrong: No green, so no autoweg? ✅ Right: No. Sign G3 decides that.

❌ Wrong: N number, so 100? ✅ Right: No. The N number says nothing about the speed.
