For update see the pictures below that show the new signs and Ukrainian messages to the Russian invaders:

      The State Road Agency of Ukraine (Ukravtodor) calls on travel organizations, territorial communities and local governments to dismantle road signs throughout the country in order to disorientate Russian troops on the ground.

      “Ukravtodor calls on all travel organizations, territorial communities, local governments to immediately begin dismantling road signs nearby,” the report says.

      Ukravtodor stressed that the number one priority for such dismantling is signposts and names of settlements.

      “The enemy has a miserable connection, they do not navigate the terrain. Let’s help them go straight to hell,” the agency stressed.
