Vehicles possessing both a free pass and a Universiade vehicle certificate or a temporary Universiade plate are allowed to pass the toll station on the expressway without being charged, the Shenzhen transportation authorities said Thursday.

Toll stations on expressways have opened a special passageway, the left or second to the left entranceway, for vehicles served for Universiade.

Authorities also warned of possible punishment of exposing images of those who seek illegal free pass without required certificates.
