I went to the gas station tonight and waited while I saw a miracle machine.
I asked the operator of the gas station what kind of apparatus it was. It turns out that the system of automatic physical examination for taxi drivers.
The driver enters his data, then he is photographed. The pressure, the presence of alcohol in the exhaled air is checked. After that, the form of the medical examination is printed out and the driver can work.
This procedure is free.
PS. I tried my own strength.
