The duty of reasonable care that States and municipalities have in maintaining roadways is extended to police officers and law enforcement agencies where the officer or agency has actual or constructive knowledge of a potentially dangerous condition. A duty to warn can arise when a municipality or a police agency creates a danger to the public or has knowledge of a dangerous situation but does not take precautionary measures to prevent injury or damages. In the absence of a statutory of special duty, police officers are not liable for their failure to provide aid to endangered individuals. This special duty can arise from actions like beginning to rescue someone. Police officers may owe a special duty following their arrival at the scene of an accident if they had knowledge of the impending danger, if the danger was obvious, if a traffic hazard existed at the time, if the officer was in direct and immediate control, and if the officer had ample opportunity to correct the situation but failed to do so.
