German Autobahn safety rules detail fines for tailgating and 20‑second lane‑change rule

tailgating fines 20‑second rule German autobahn road safety regulations Flensburg penalty points

In Germany, tailgating on the autobahn is identified by the ADAC as a major safety problem, accounting for roughly 12.9 % to 17.2 % of all highway accidents in 2023. The road traffic regulations require drivers to keep a safe distance, with trucks over 3.5 tonnes mandated to maintain at least 50 m when travelling above 50 km/h. The common “half‑tacho rule” advises a gap of half the vehicle’s speed in metres.

The “20‑second rule” supplements the right‑hand traffic obligation (Rechtsfahrgebot, § 2 StVO) by stating that if the right lane will be free for more than 20 seconds before the next overtaking, drivers must shift to that lane. Failure to comply can lead to a fine of €80 and one penalty point in Flensburg. The rule is not codified in the StVO but originates from case law and is promoted by the ADAC.
