Lime's alcohol test, which was introduced over the carnival season, is intended to test the reaction times of scooter renters in order to check their fitness to drive. The test will be used in the German carnival strongholds of Cologne and Düsseldorf.

People who repeatedly fail the test would be banned from Lime for several hours and would have to abandon the scooter. The app-controlled alcohol controls should apply for the period from Altweiber up to and including Violet Tuesday (February 8th to 13th)
