Three out of ten serious drink driving accidents in Denmark happen during the summer months. From 2020 to 2024, nearly a third of all people killed or seriously injured in such crashes were hurt in June, July, or August. The Danish Road Safety Council urges everyone to leave the car at home if drinking, especially new drivers, and to help prevent others from driving under the influence.

Over half of the breathalyzers tested by MHF Test Lab gave dangerously inaccurate readings, with some showing 0.0‰ even when the driver was over the legal limit. The test, done with Testfakta, highlights serious safety risks. Only fuel cell-based models like Dräger 4000 and Dignita AM-7000 showed reliable results, while cheaper semiconductor devices failed.

Intoxicated drivers caused 37% of fatal crashes in Finland (2014–2023), with two-thirds showing signs of substance dependence.
