Compulsory direction signs
A round blue sign with a white arrow is a command: you must follow the direction of the arrow. Sign D1 stands at a roundabout and only says which way you drive, not who goes first. Sign D2 says on which side you must pass the sign, for example at a traffic island.
The signs
D1 · Roundabout: follow the mandatory directionWho has priority on a roundabout is set by the priority signs and shark's teeth at the entry, not by this sign; without them, traffic from the right goes first.
D2 · Pass on the side the arrow showsUsually placed on a traffic island — keep to the side it points to.
D4 · Mandatory direction: straight aheadA blue disc commands; a red-ringed disc forbids.
D5 · Mandatory direction: turn rightYou must turn as the arrow shows, whatever your navigation says.
C4 · One-way road (sign with a horizontal arrow)Traffic on this road runs only in the direction of the arrow; do not turn into it against the arrow.
D3 · Pass on either sideYou may pass the sign on either side, for example at a traffic island; choose the side that suits your direction.
D6 · Mandatory direction: straight ahead or rightYou must follow one of the arrows; turning left is not allowed here.
D7 · Mandatory direction: left or rightYou must turn left or right; going straight ahead is not allowed here.
What you do in practice
- At a roundabout the shark's teeth and priority signs at the entry decide who goes first, not sign D1.
- At D4 you go straight on, at D5 you turn right; at D6 and D7 you may choose between the two directions on the sign.
- A blue rectangular sign with an arrow (C4) is not a command but the sign for a one-way street.
The mistake many people make
Taking a round blue sign for advice. Round and blue means: compulsory.
