French police have warned drivers to be cautious of deer appearing drunk after eating fermented fruit in the Saône-et-Loire region.
This phenomenon creates an immediate road-safety risk because intoxicated animals lose their natural instincts and behave unpredictably near moving traffic. Such erratic movements increase the likelihood of sudden collisions in rural areas.
The Gendarmerie de Saône-et-Loire issued the alert after observing wild deer acting unpredictably near Charnay-lès-Mâcon in the Burgundy region. The police force shared video footage of a deer running in circles and appearing disoriented.
A police spokesperson said the animals may have been snacking on fermented or decomposing vegetation, causing the animal to appear drunk. This intoxication occurs when sugars in fallen fruits or plants ferment, creating alcohol that the animals ingest.
Authorities said the Gendarmerie de Saône-et-Loire posted the video to illustrate how these animals act "totally unpredictably" after consuming fermented fruits or decaying plants. The behavior makes it difficult for drivers to anticipate where the animal will move.
Police said drivers should be vigilant in wooded areas and to slow down because of intoxicated deer. The warning specifically targets those traveling through the central-eastern part of France during this spring season.
Officials said the risk is highest in areas where decaying vegetation is plentiful. By reducing speed, drivers can better react to animals that may suddenly dart across the road without the typical hesitation or flight response seen in sober wildlife.
“The deer may have been snacking on fermented or decomposing vegetation, causing the animal to appear drunk.”
This incident highlights a seasonal biological hazard where natural fermentation in forest floor vegetation creates a public safety issue. When wildlife ingest ethanol from fermented fruit, their impaired motor skills and lack of fear can lead to unpredictable traffic accidents, shifting the burden of safety onto drivers to maintain lower speeds in rural corridors.
