The Indiana State Police (ISP) have a new tool to enforce alcohol-impaired driving this Labor Day weekend. The National Highway Traffic Safety Administration and Indiana Criminal Justice Institute recently purchased 777 portable breath test devices for use by ISP troopers. In every state, it is illegal to drive with a blood alcohol concentration (BAC) of .08 or higher. In Indiana, drivers under 21 with a BAC of .02 or higher are subject to fines and a license suspension for up to 1 year. Since 2017, more than 2,600 portable breath tests have been purchased for 150 law-enforcement agencies across Indiana. The Alco-Sensor FSTs also include passive sniffers that can sense alcohol in the air around a person or an open container.
