Nighttime Vacation Driving: ACV's Safety Tips for Preventing Driver Fatigue
The German automotive club ACV Automobil-Club Verkehr has published safety recommendations for drivers departing on vacation at night or in the early morning. According to research cited by the ACV, 17 hours without sleep can reduce driver performance to levels equivalent to 0.5 per mille blood alcohol content, while 22 hours without sleep can reduce performance to 1.0 per mille. In July 2026, summer vacation travel has been creating increasingly heavy traffic on German motorways for several weeks as peak departure season approaches. The ACV recommends getting rest before taking the wheel and, when possible, traveling with a second driver to take turns at the controls.
