An operator of an authorized emergency vehicle is _________ relieved by the traffic code from safety regulations.

The operator of an authorized emergency vehicle is not relieved by the traffic code from safety regulations. While emergency vehicles may have certain privileges, such as the ability to exceed speed limits or go through red lights when responding to emergencies, they are still obligated to follow safety regulations to ensure the safety of everyone on the road, including other drivers, pedestrians, and themselves. This approach emphasizes the importance of responsible driving, even in emergency situations, to prevent accidents and protect the public.

Other options suggest various conditions under which emergency vehicle operators might be exempt from safety regulations or imply a blanket exemption, which is not the case. The traffic code recognizes that while these operators have specific duties, the need for safety does not diminish, thereby reinforcing the importance of adhering to safety regulations at all times.
