Note: The above does not apply to people engaged in official or emergency related matters provided that these drive with due regard to the safety of other road users. This includes traffic and police vehicles and emergency vehicles such as ambulances or fire engines). Emergency vehicles are on official business and often involved with emergency rescue where the life of others are in their hands. As such you must always give way immediately to any official vehicle sounding a warning device (e.g. a siren or a bell) to enable them to get to their final destination immediately.
