A patrol crew of the Elze police station checked a car in Gartenstraße in Gronau (Leine) during the night from 13 to 14 November 2026.[1] The driver was a 26-year-old man whom officers suspected of having previously consumed intoxicants.[1] An Elze patrol stopped the man in Gartenstrasse on the night to Saturday, 14 November.[2]

An on-site urine drug pre-test reacted positive for THC, a psychoactive substance from the cannabis plant.[1] Officers then took a blood sample from the driver and prohibited him from continuing to drive.[1] The Hildesheim police statement likewise says a blood sample was taken and the onward journey was stopped.[3]

Police opened administrative offence proceedings against the driver for driving under the influence of intoxicants under section 24a of the Road Traffic Act.[3] The statement says a first-time violation of this kind typically draws a 500-euro fine, two points in the driving fitness register and a one-month driving ban.[1] Hilde-News added that the decisive factor for the proceedings is the THC level in blood serum, citing the 3.5 nanograms per millilitre limit.[2]
