About one in seven drivers on California roadways may be under the influence of drugs, according to a new survey by the state’s Office of Traffic Safety.
The survey released Monday tested more than a thousand drivers on weekend nights in nine California cities.
Roughly 14 percent of those drivers tested positive for drugs that might impair driving. Half as many of the drivers surveyed by the OTS tested positive for alcohol.
Compared to national statistics, the number of drug-impaired drivers has increased throughout the years. It reinforces officials’ belief that driving under the influence of drugs – in addition to alcohol – is a serious and growing problem, said Christopher J. Murphy with the OTS.
