In an effort to raise HIV awareness among professional drivers—truck drivers, in particular—Cambodia’s Public Works Ministry and the National AIDS Authority at the Ministry of Health are teaming up to add questions about the virus to its written driving test, The Phnom Penh Post reports.

According to the article, the test will now feature a dozen questions about HIV in addition to those focused on driving techniques, the rules of the road and how to administer first aid to accident victims.

“This marks the first time questions about HIV/AIDS have been included in a driving test,” said Ung Chun Hour, the Public Works Ministry’s director general of transport. “It is important that drivers—particularly professional drivers—know about HIV/AIDS. Professional truck drivers live far from home and are more likely to use sex partners.”
