On Monday 2 November 2026 police checked a 23-year-old driver from Haan on the L11 between Nideggen and Brück after tips about reckless driving.[1] A road user had previously reported that a car had driven up very closely behind him several times on the A1 and repeatedly flashed its headlights.[1] On the L33 the driver had additionally carried out several dangerous overtaking manoeuvres, pulling back in so closely in front of the witness that the witness had to brake hard to avoid a collision.[1] Officers found the described car shortly afterwards on the L11 and subjected it to a control.[1] The 23-year-old driver rejected the accusations and said he had merely overtaken other vehicles.[2]

During the check officers observed signs of possible drug consumption, and a voluntarily conducted saliva test was positive for cannabis.[1] The man then had blood taken at a hospital, was not allowed to continue his journey, and officers seized his driving licence.[2] A criminal proceeding is now being conducted against the 23-year-old on suspicion of endangering road traffic as a result of consuming intoxicants.[1]
