While THC is legal in various states, truck drivers aren’t allowed to use it. They are already subject to random blood and urine tests. However, now truckers could face having their saliva tested to detect marijuana consumption. 

Truck drivers may face saliva tests to detect THC 

The Department of Transportation (DOT) wants to implement saliva testing to deter THC use among truck drivers. This new testing method should roll out later in the year. 

It can detect marijuana use within 72 hours of consumption. According to Freight Pulse, because it provides a shorter detection window, it may provide some drivers with an opportunity to use marijuana without being subject to routine drug tests. 

But if a semi-truck operator receives a random request for a drug test they will be unaware if they need to provide a urine or oral fluid sample until they arrive at the collection facility. This could prevent truckers from altering their habits in an attempt to go undetected. 

While observed urine testing is the most effective method for marijuana testing, there are privacy concerns. Some people don’t enjoy being watched as they pee. However oral-fluid collections can be directly observed. 

It will also reduce the ability to tamper with the process as some truck drivers can pay for clean urine to pass off as their own. 

But testing more drivers this way could worsen the driver shortage. If more truckers are caught operating under the influence then more could be removed from service. 

Some critics argue that it may encourage drug use for off-duty drivers and may impair their abilities when they return to work.
