The checkpoint is only for empty cars, but customs works very slowly, both on the Belarusian side and on the Lithuanian side, there are no insurance companies and you cannot buy insurance, there are no customs brokers on the Lithuanian side, because of this, you cannot make a declaration at the very crossing, for example, to a container when leaving the country.
Thanks to the Lithuanian customs and border guards for the instant pass, the border control on the Belarusian side was 5 minutes, but the customs had to wait 2 hours.
