The U.S. Department of Transportation (DOT) is proposing a temporary change to its drug testing rules. Currently, rules require oral fluid tests in some situations, but because the necessary laboratories are not certified, these tests can't be performed yet. The new rule aims to temporarily allow directly observed urine tests instead until oral fluid testing becomes available. This interim rule will only be in place until the required facilities and procedures for oral fluid testing are established.
Simple Explanation
The U.S. Department of Transportation wants to change the rules for drug testing trucks and buses drivers because they can’t use the spit test yet, so for now, they’ll watch the pee test closely to make sure it’s done right. This change is just temporary until they have everything ready for the spit test.
