Chechen leader Ramzan Kadyrov donned a traffic policeman's cap to personally inspect cars with banned tinted glass windows, local television reported.
An eight-minute video of the inspection, shot by Chechen television and aired in the republic, was posted online by blogger Andrei Malgin on Monday. The undated video shows Kadyrov wielding a loudspeaker and checking drivers' documents. He speaks mostly in Chechen.
Kadyrov holds the rank of a police general, though not of the traffic police.
Chechen authorities have been campaigning against tinted car windows since 2009, saying such vehicles are favored by Islamist insurgents.
