Temporary signs and sign hierarchy

The sign hierarchy

When several forms of regulation apply at the same time, there is a fixed order of priority. The one with the highest rank overrides the others.

Temporary signs in practice

Temporary signs for roadworks have a yellow background and replace the fixed signs in the work area. They are set up to direct traffic safely past.

• Reduced speed limit at roadworks applies even if the fixed sign shows higher speed.
• Temporary road markings (yellow lines) overrides white permanent markings.
• The signs are removed when the work is finished, and the fixed signs apply again.

Common traps

• I think that traffic lights always precede signs. Police and temporary signs have a higher rank.
• Forgetting that road markings have a lower priority than signs. If a sign says something other than marking, the sign applies.
• Ignores that roadworks and temporary signage can completely change the driving pattern.

When police direct

Police signs override all signs and signals. You must always follow the police’s instructions, even if the traffic light is green.
