Indiana Passes “Good Samaritan” Law to Protect Dogs in Hot Cars, by Nicole Pallotta, June 13, 2017:
On April 26, 2017, Governor Eric Holcomb signed House Bill 1085 into law, making Indiana the ninth state to pass a “good Samaritan” hot car law allowing a citizen to forcibly enter a motor vehicle under certain conditions to rescue a companion animal confined inside. Indiana’s new law, which goes into effect July 1, is stronger than many hot car laws in that it allows a regular citizen (as opposed to only law enforcement) to break into a car to rescue an animal, yet it is significantly weakened by not providing full immunity from civil and criminal liability, unlike the other eight laws that allow citizens to act. Instead, under Indiana’s law, a person who breaks into a vehicle to remove an animal in distress is required to pay for half of the repair costs directly caused by the forcible entry.
