Private companies employing drivers were yesterday urged to closely monitor their staff to ensure they are not taking to the Kingdom’s roads under the influence of drugs.

Pov Maly, a Ministry of Public Works and Transport official, said drivers in industries such as construction were rarely caught, because they tended to be on remote roads where traffic laws weren’t heavily enforced.

“I want [govern-ment] officials to work with company owners to check drivers,” he said at a road safety seminar in Phnom Penh. To make traffic laws clearer, the ministry will publish 10,000 booklets about road safety.
