Alcohol Check at Brussels Christmas Market: Stay Safe This Holiday Season
Free Breathalyzers Offer Holiday Revelers a Reality Check in Brussels
Brussels Christmas market-goers are getting a sobering dose of reality alongside their glühwein and waffles, thanks to a new initiative offering free blood alcohol content (BAC) testing. The service, provided by the tech company Fline, aims to promote responsible drinking and deter drunk driving during the festive season.
“High Alcohol: no driving, 1 h 25 before driving, 179 € penalties,” the machine displays after Aslan, a market visitor, used the device. He admitted to having two whiskies but emphasized he wasn’t planning to drive. “I tested out of curiosity,” he said, reflecting a sentiment shared by many who see the service as a useful tool in a social setting.
A Growing Trend in Public Safety
Fline, a Wavre-based company founded in 2022, is expanding the use of these devices across Europe, now operating in ten countries. The company believes proactive awareness is key to changing behavior. “With this device, we can make people think about the consequences before they even consider getting behind the wheel,” explains Marvin Pottier of Fline.
The company collaborates with sports clubs, bars, and even public authorities in Belgium, Switzerland, France, and Ireland, demonstrating a growing recognition of the need for accessible alcohol awareness tools.

“There should be more tests like this in public spaces, in bars, and nightclubs,” suggests Giovanni, a market visitor. Margaux, from Waterloo, agrees, adding, “The fact that it’s free encourages people to use it.” Rory, an Irish expat living in Brussels, playfully tested after enjoying a mulled wine, confirming he was still at zero and free to enjoy another drink.
Addressing a Critical Public Health Issue
According to the World Health Organization, road traffic crashes cause approximately 1.3 million deaths globally each year, with drink-driving being a significant contributing factor. In Belgium, despite ongoing campaigns, alcohol remains a factor in a substantial percentage of road accidents. The Belgian Institute for Road Safety (VIAS) reports that alcohol is involved in approximately 15% of fatal accidents.
The Brussels city government is not incurring any costs for the initiative. Fline secured a location rental, and the installation is sponsored by Stellantis. Over the duration of the Christmas market, Fline anticipates administering around 65,000 tests.

Local police confirm that alcohol and drug checkpoints are being intensified as part of the annual Bob campaign (November 28th to February 2nd), but report no significant increase in drunk driving incidents specifically linked to the Christmas market festivities. “We are not recording an increase linked to the period of Christmas celebrations,” a police spokesperson stated.
