A total of 2.7% of them were detected positive, a decrease of 3.1% compared to last year. The number of alcohol checks has also remained almost stable: 324,468 people were subjected to them this summer compared to 330,245 in 2017.
The only downside is the high percentage of positive drivers after an accident with death or injury: almost 10%, proof of the total incompatibility between alcohol and driving, the institute still points out.
The campaign was conducted from June 8 to September 3. Over these three months, nearly 82,000 motorists were checked in Wallonia. In Brussels, 22,673 tests were carried out, of which 2.8% (631) were positive. Flanders has the lowest number of positive results. They were 2.5% in this case this summer, out of 219,922 controls (221,771 and 2.9% in 2017).
