Supply chain stalled by 72,000 truckers who failed strict drug tests

A dire truck driver shortage that’s wreaking havoc on the US economy is getting worse — and it’s being fueled partly by tough federal drug-testing restrictions that were imposed nationwide last year, industry officials told The Post.

More than 72,000 truck drivers have been taken off US roads since January 2020 because they have failed drug tests that are now required by the Drug & Alcohol Clearinghouse, a 22-month-old registry established to increase safety on US highways, according to government data.
