A growing number of traffic accidents on Czech roads is caused by drivers on drugs, police president Tomáš Tuhý said in a debate on Czech Television on Sunday. According to police statistics since 2010 50 people killed on Czech roads were victims of accidents involving drug abuse. The police president said traffic police had intensified check-ups in this respect, but were being hampered by a lack of funds. He said the aim was for every officer on the road to be equipped to detect drug abuse. In 2010 the police registered 527 cases of drivers on drugs, mainly on crystal methamphetamine; they registered the same number in the first quarter of this year. Last weekend an officer was killed by a driver on crystal methamphetamine.
