Utah CDL drug testing runs on the standard federal framework, but the Clearinghouse's direct impact on Utah DLD's ability to process your CDL is worth understanding clearly before it ever becomes relevant.

In This Guide

The DOT 5-Panel Drug Test

CategoryWhat It Detects
MarijuanaTHC metabolites
CocaineCocaine and benzoylecgonine
AmphetaminesAmphetamine, methamphetamine, MDMA, MDA
OpiatesCodeine, morphine, heroin (6-AM)
PhencyclidinePCP

This is the standard federal panel applied to CDL holders nationwide, not a Utah-specific test.

The Federal Random Testing Rate

The FMCSA minimum random drug testing rate remains 50% of a carrier's driver pool annually, with a 10% minimum random alcohol testing rate, a federal standard applying uniformly in Utah as in every other state.

The FMCSA Clearinghouse and Utah DLD

A "prohibited" Clearinghouse status stops Utah DLD from processing your CDL entirely. If the FMCSA Drug and Alcohol Clearinghouse reports a driver as prohibited from operating a CMV, Utah DLD cannot issue, renew, upgrade, or transfer that driver's CDL or CLP until the return-to-duty process is complete and the Clearinghouse clears the driver.

The Marijuana Question
