Truck drivers could soon face oral fluid testing for controlled substances under a new directive from the U.S. Department of Health and Human Services.

The revision has become necessary because several products have appeared on the market making it easier to fake urine samples, it added.

It is expected to take DOT quite some time to come up with a specific testing program for oral fluid specimens, if at all.

A report said unresolved scientific and legal issues were holding up the proposal, which has been under review since Congress passed the legislation in 2015.

In its latest move to bolster road safety, the U.S. Federal Motor Carrier Safety Administration has also doubled the random drug testing rate for commercial drivers to 50% of driver positions.

In this country, the Canadian Trucking Alliance has been pushing for a zero-tolerance policy on drugs and alcohol.

It has urged the federal government to introduce mandatory drug and alcohol testing for truckers, saying Ontario auditor general’s report on commercial vehicle enforcement supports its case.

In her annual report, Auditor General Bonnie Lysyk said the lack of drug and alcohol testing is a potential safety
