Random drug testing at work is legal for Utah private employers, as long as it happens inside a written policy that follows the Utah Drug and Alcohol Testing Act.
For CDL drivers it goes further: random testing is not optional, it is a federal requirement under 49 CFR 382.305. So a Utah employer can be running two random programs at once, under two different rulebooks.
This page covers both, from the employer's side and the employee's side.
This page explains the rules in plain language. It is not legal advice. Confirm the details of your program with your employment counsel.
Yes, within a written policy. The Act does not use the word "random." What it says is that testing under the employer's written policy "need not be limited to circumstances where there are indications of individual, job-related impairment" (Utah Code 34-38-7(3)).
That is the sentence that makes suspicionless testing, including random selection, available to a private employer. It comes with the requirement in 34-38-7(1) that the testing be "carried out within the terms of a written policy which has been distributed to employees and is available for review by prospective employees."
Random testing still has to fit one of the purposes in 34-38-7(2): impairment, accidents or theft, safety, or productivity, quality and security.
If you are looking at random drug testing laws by state, keep in mind this page covers Utah only. Other states write their own rules.
For public employers, the definition is different. Utah's chapter for local governments defines random testing as unannounced testing of an employee "selected for testing by using a method uninfluenced by any personal characteristics other than job category" (Title 34, Chapter 41). That chapter applies to counties, cities, school districts and similar bodies, not to private businesses.
The Act gives employees specific protections. If you are an employee, this is what the statute says you are entitled to.
A written policy you have seen. Testing must follow a written policy that has been distributed to employees (34-38-7(1)).
Testing on the clock. Testing of current employees must happen "during or immediately after the regular work period" and is "deemed work time for purposes of compensation and benefits" (34-38-5(1)).
No cost to you. The employer pays all costs of testing it requires, including transport if you are tested away from the workplace (34-38-5(2)).
Privacy. Collection must be done "with due regard to the privacy of the individual being tested" and under sanitary conditions (34-38-6(2) and (3)(a)).
A chance to report medications. The collection documentation must give you an opportunity to identify prescription or nonprescription drugs you use, and other relevant medical information (34-38-6(4)(b)).
A confirmation test. A screen alone is not a failed test. It must be confirmed by gas chromatography, GC-mass spectroscopy or a comparably reliable method before an employer acts on it (34-38-6(6)(b)).
Confidentiality. Test-related information is a confidential communication with limited permitted uses (34-38-13).
Management is tested too. When an employer tests, management must "submit to the testing themselves on a periodic basis" (34-38-3(1)).
A remedy for a wrong result. The Legislature did not intend to stop an employee from "seeking damages or job reinstatement" if the employer acts on an inaccurate result (34-38-1(2)). The limits on those claims are in 34-38-10.
One thing to know before declining a test: a refusal to provide a sample is a basis for discipline, up to termination, under 34-38-8.
For non-CDL staff, the Utah Act sets the conditions above but no selection rate and no selection method. Those come from your policy. A defensible non-DOT random program usually answers four questions in writing:
Write it into the policy before the first draw. See writing a workplace drug testing policy in Utah.
For drivers covered by Part 382, the rules are federal and fixed. From 49 CFR 382.305:
An employer can use a consortium or third-party administrator to run selections, and drivers can be part of a larger pool, but the employer must make sure the right rate is tested (382.305(j)(2)). A self-employed driver with no other covered employees must be in a random pool of two or more (382.103(b)).
More detail: DOT random drug testing requirements and how a DOT consortium works.
Yes, if it is done under a written policy distributed to employees (34-38-7). The Act allows testing not tied to signs of impairment.
For current employees, yes. Testing time is work time for compensation and benefits (34-38-5(1)).
50% for drugs and 10% for alcohol, unchanged for 2026 per DOT's January 8, 2026 announcement. The baseline is in 49 CFR 382.305(b).
