Officers found cannabis in one car. While the number of drivers who test positive for alcohol is decreasing slightly, more and more drivers appear to be driving under the influence of drugs. “Compared to the past, we have noticed that it is happening more often,” says Charlotte Kempinck, head of Safety department at PZ Arro Ypres. “Giving exact figures is a bit more difficult. That is why we pay a lot of attention to drugs in traffic today. Anyone who drives into our facility and has to stop is obliged to take a breath test. If necessary, a drug test will also follow.”
