As summer vacations kick off in Bavaria and Baden-Württemberg, the ADAC warns of one of the worst traffic weekends of the year.

Heavy congestion is expected on major highways, particularly the A7 between Hamburg and Flensburg, and the A6 between Mannheim and Nuremberg.

Travelers should anticipate long delays, especially on the A1 due to construction work.

With all federal states on holiday, the roads will be crowded with vacationers and day-trippers alike.

The ADAC advises avoiding travel on Friday, Saturday, or Sunday, or at least starting later in the afternoon to minimize wait times.

For those taking the train or flying, expect full services and plan for extra time at stations and airports.
