A driver under the influence crashed into the back of a police car in Lucerne.
Earlier this week, the police car stopped at a pedestrian crossing in Hochdorf when a following car failed to brake in time and crashed into the back.
A roadside drug test on the 42-year-old driver came back positive.
He was taken for further blood and urine tests, and his driving licence has been immediately suspended.
No one was injured.
