The image shows a close-up of a handheld device, specifically a breathalyzer, which is used to measure the concentration of alcohol in the breath. The screen of the device displays a reading of 0.21, indicating that the person being tested has consumed alcohol. The background includes a blurred hand holding the breathalyzer and some text on the screen, likely displaying the alcohol content in milligrams per liter (mg/L). The breathalyzer is a common tool used by law enforcement to determine if a driver has been drinking while driving.
