"They (checkpoints) may be set up everywhere – each county decides according to its capabilities and tactics," Ramunas Matonis, a spokesman for the Police Department, told.
"Currently, random checks are done, but all (passing cars) can be stopped at some point, depending on the traffic situation," he said.
Vehicles can be stopped for checks in and outside cities and towns, the spokesman said, adding that mobile checkpoints will operate at night, too.
