State Law: Good Samaritan
  • Good Samaritan law enacted
  • No Good Samaritan law enacted

Fear of police involvement is the most common reason for not calling 911 during a medical emergency. In recognition of this fact, many states have enacted laws that exempt from arrest and prosecution any victim or “Good Samaritan” who renders aid in a drug or alcohol-related emergency. Commonly referred to as ‘Good Samaritan,’ ‘911 Lifeline,’ or ‘Medical Amnesty/Immunity,’ these laws seek to offer limited, situational immunity as an incentive for taking life-saving measures. The above map identifies Good Samaritan laws that are specific to alcohol or alcohol/drugs. It does not include Good Samaritan statutes that are exclusive to drugs.

**Drunkenness is not considered a crime in some states; therefore, the figures may vary widely from state to state

Limited, incomplete, or no data were reported by the District of Columbia, Florida, Illinois, and New York in the 2016 Uniform Crime Report. Data should be used with caution and should not be compared to other states or previous year data.

Note: Because the number of agencies submitting arrest data varies from year to year, users are cautioned about making direct comparisons between 2016 arrest totals and those published in previous years’ editions of Crime in the United States. Further, arrest figures may vary widely from state to state because some Part II crimes of the Uniform Crime Report are not considered crimes in some states.
