Subject: Examples of Job Hopping by Commercial Drivers after Failing Drug Tests
Millions of American drivers hold commercial driver’s licenses (CDL), allowing them
to operate a variety of commercial vehicles, such as school buses, cargo vans, and
tractor trailers. While most commercial drivers do not test positive for drugs and
alcohol, Department of Transportation (DOT) data show that each year from 1994
through 2005, from 1.3 percent to 2.8 percent of truck drivers tested positive for the
presence of illegal drugs under random testing. However, as our recent investigation
shows, the current DOT drug testing process can easily be defeated with products,
such as synthetic urine, that are widely available for sale.1 To help prevent accidents
resulting from commercial drivers who use drugs and alcohol, federal law requires
commercial drivers to be tested for drug and alcohol use.2 Specifically, the testing is
required as part of the preemployment screening process, on a random basis while
employed, and following an accident involving a fatality. Commercial drivers who fail
a drug test, refuse to test, or otherwise violate the drug testing regulations are
required to complete a return-to-duty process before returning to the road. The
return-to-duty process is guided by a substance abuse professional and must include
education or treatment, return-to-duty testing, and follow-up testing.
However, among the commercial drivers who test positive for illegal drugs, an
unknown number continue to drive without completing the required return-to-duty
process. Those who do not go through the return-to-duty process and continue to

drive are called job-hoppers.3 A job-hopper tests positive for one carrier; is fired,
quits, or is not hired; and subsequently tests negative on a preemployment test for
another carrier. DOT regulations require that employers—with the applicants’
consent—request the applicants’ drug testing records from previous employers.4
Because they avoid the return-to-duty process and can choose to not disclose their
prior failed drug tests, these commercial drivers could continue to drive and use
drugs. In addition to abstaining from drug use for a short period in order to pass the
second test, a wide variety of available commercial products can mask drug use and
may allow commercial drivers to pass drug tests even as they continue to use illegal
drugs.5
Because of the significant danger of commercial drivers circumventing the return-toduty requirements and driving shortly after a failed drug test, you asked us to identify
illustrative cases of job-hopping commercial drivers based on data that you provided
to us from a third-party administrator.6 Specifically, you asked us, to the extent
possible, to determine (1) the current employment status for selected employees who
passed the drug test after recently failing the test; (2) whether the failed test was
known to the current employer prior to, or after, hiring the individual; and
(3) whether the prior positive test result was disclosed on the application for current
employment.
To address the objectives, we analyzed the drug test results data provided to the
House Committee on Transportation and Infrastructure from a third-party
administrator. We assessed these data for reliability and found them to be sufficiently
reliable for our purposes. The drug test data covered 698 drivers who, within the last
5 years, tested positive for one employer and negative for another employer. In our
analysis of the data, we narrowed the focus and identified 43 cases from the past 2
years where commercial drivers had tested positive for drugs with one employer
then, within 1 month, tested negative with another employer. To develop case studies
that would meet our objectives, we interviewed employers to determine (1) if the
commercial driver is currently employed at the company, (2) if the employer was
aware of the positive drug test prior to or after hiring the commercial driver, and (3)
if the prior positive test was disclosed on the application for current employment. In
addition, we interviewed selected commercial drivers to determine their current
employment status and the circumstances surrounding their drug tests. For these 43

There are little data on the number of drivers who complete the return-to-duty process. A director of
the Substance Abuse Program Administrators Association conservatively estimates that less than half
of CDL holders who test positive or refuse to test successfully complete the return-to-duty process
before returning to their jobs. See GAO, Motor Carrier Safety: Improvements to Drug Testing
Programs Could Better Identify Illegal Drug Users and Keep Them off the Road, GAO-08-600
(Washington, D.C.: May 15, 2008).

In November 2007, we reported that 75 percent of the 24 urine collection sites we tested failed to
restrict access to items that could be used to adulterate or dilute the specimen, meaning that running
water, soap, or air freshener was available in the restroom during the test. See GAO-08-225T.

cases, we also reviewed relevant state department of motor vehicle reports, police
reports, and other public records.
In summary, for all 43 cases, we contacted and informed the employer that the
commercial driver had a previous positive drug test and made inquiries concerning
application and employment information regarding the commercial driver. Employers
for 37 of the 43 identified drivers responded to our inquiry.7 For all 37 of these cases,
the employers stated that the commercial driver did not disclose prior positive test
results. For 19 of the 37 cases, the driver was subsequently hired. The other 18 drivers
were not hired for several reasons, including instances where the previous employer
disclosed the positive drug test when asked by the prospective employer.
We performed our investigative work from March 2008 to June 2008 in accordance
with standards prescribed by the President’s Council on Integrity and Efficiency.
Examples of Commercial Drivers Who Job Hopped after Failing Drug Tests
Using the drug test results data provided by your staff through a third-party
administrator, we identified 43 cases where commercial drivers had tested positive
for illegal drugs, such as cocaine, marijuana, and amphetamines, with one employer
and within 1 month tested negative with another employer. For all 43 cases, we
contacted and informed the employer that the commercial driver had a previous
positive drug test and made inquiries concerning application and employment
information regarding the commercial driver. Employers for 37 of the 43 identified
drivers responded to our inquiry.
Of the 37 drivers for which we received employer responses, our investigations found
that 19 of them were subsequently hired even though the employer stated that a
positive drug test would have disqualified them. As part of their employment, these 19
drivers drove commercial vehicles, including trucks carrying hazardous materials for
periods of 1 month to over 1 year. In fact, several drivers were currently on the road
driving commercial vehicles at the time we contacted the employer. When we
informed employers about the positive tests, the companies quickly terminated the
commercial drivers. For the other 18 cases, the driver did not drive commercial
vehicles for the employer for several reasons, including because a previous employer
disclosed the positive drug test or the driver did not complete the orientation
process.
In addition, as part of our investigation, we were able to interview 12 of these 37
commercial drivers to determine their current employment status and the
circumstances surrounding their drug tests. In these discussions, we found that none
of these 12 drivers, after being notified of failing their drug test, had undergone an
evaluation by a Substance Abuse Professional (SAP) before applying for a new job.8
7

The employers for the other 6 cases did not respond to our inquiry or stated that they did not have
application information regarding the commercial driver.

8

One commercial driver did state that he subsequently complied with the requirement of a Substance
Abuse Professional evaluation. The commercial driver said that he went through this program because
the employer subsequently found out about the prior positive test for drugs.

Page 3

GAO-08-829R

In fact, only 7 of these commercial drivers indicated they were aware that such an
evaluation was required.
The following provides more detailed examples from several of the cases we
investigated.

9

•

Case 1: A Texas truck driver tested positive for marijuana on June 10, 2007.
The driver then applied for employment at a neighboring company
approximately 2 weeks later. His first preemployment test was inconclusive
because of an invalid sample. The truck driver subsequently tested negative
for drugs in a second preemployment test9. After passing the second
preemployment test, the driver was employed by the company hauling general
freight. A company official stated the company was unaware that the driver
had failed a previous drug test because the driver did not disclose it on his
employment application. The truck driver was fired after we notified the
company of the positive drug test.

•

Case 2: On October 29, 2007, an Oklahoma truck driver tested positive for
marijuana. The driver subsequently passed his preemployment drug test for
another company 9 days later10. The driver stated that he “took appropriate
measures to clean his system before applying at the second employer”. A
company official stated that the company was unaware of the prior drug test
and that the driver had been employed for a couple of months but was no
longer working for the company. The driver stated that he is not currently
driving commercial vehicles.

•

Case 3: On May 14, 2007, a Tennessee truck driver tested positive for cocaine.
The commercial driver passed a preemployment drug test for a second
company 8 days later11. Prior to his drug tests, the driver was charged with
possession of a controlled substance. According to the employer, the driver
was employed at the company for several months driving trucks containing
cargo and hazmat material. The employer indicated that the driver is no longer
employed at the company.

•

Case 4: A Georgia truck driver tested positive for marijuana on March 5, 2007.
About 3 weeks later, the driver passed the preemployment drug test for a
second company12. The driver was employed by the company for about 7
months driving a truck containing cargo and hazmat materials. According to a
company official, the company would not have hired the truck driver if
officials were aware of the prior drug test because it is the company’s policy
not to hire a driver who has failed a drug and alcohol test within the past 5

Date of negative drug test for Case 1 is July 3, 2007.

Date of negative drug test for Case 2 is November 7, 2007.

years. According to the employer, the driver is no longer employed at the
company.
•

Case 5: On July 12, 2006, a Michigan commercial driver tested positive for
cocaine. The driver passed the preemployment drug test for a second company
9 days later,13 but was not subsequently hired by company because, according
to a company official, he did not meet the company’s qualifications. Prior to
his drug tests, the commercial driver was responsible for a truck accident in
which he tested positive for cocaine. The commercial driver also pled guilty to
operating/allowing intoxicated person to operate a motor vehicle in 2007.

The table in enclosure I provides a description of the other 38 cases that we
investigated.
On May 30, 2008, we briefed the DOT officials on the results of our investigation. We
informed the officials that GAO notified the employers for all 43 cases of drivers with
prior positive drug tests.
