29. Siren

A siren is a loud warning device used to attract attention and warn people that an emergency or priority vehicle is approaching. Sirens are commonly fitted to vehicles such as ambulances, fire engines and police vehicles and may produce alternating or changing tones so they can be recognised quickly.

When an emergency vehicle approaches with its siren operating, road users should remain alert, identify where the vehicle is coming from and safely make room for it to pass. The exact priority rules and permitted use of sirens vary between countries.
