The Whiz Guys offer the service of being a Consortium/Third Party Administrator (CTPA) for your company. This means they provide your company with an initial pre-employment/baseline alcohol screen followed by random alcohol testing services. The Whiz Guys follow the guidelines set forth by the FMCSA which requires 10% of employees have random testing yearly. They enter your employees into a pool and use scientific program (randomizer) to make selections for random testing. The Whiz Guys contact your DER to schedule the random alcohol test.

In cases that involve post-accident drug and alcohol testing, The Whiz Guys offer after hours and on-site services. Drivers are required to have an EBT by a BAT following a motor vehicle accident. If post-accident testing is needed, a BAT will conduct the test and a print out of positive or negative alcohol test with date and time will be provided immediately following the test.

The tasks you actually perform qualify you as a safety-sensitive employee, not your job title. Also, some employees, like managers and supervisors, may be qualified for these jobs but not currently performing them. Do they have to be tested as well? In most cases, yes...if that employee may be asked at a moment’s notice or in an emergency to perform a safety-sensitive job. Be sure to check industry specific regulations for further clarification.

NOTE: Employers (and C/TPAs) subject to more than one DOT Agency drug and alcohol testing rule may continue to combine covered employees into a single random selection pool. However, companies (and C/TPAs) doing so must test at or above the highest minimum annual random testing rates established by the DOT Agencies under whose jurisdiction they fall. For example, an employer having both FMCSA- and FRA-covered employees in one pool must test, as a minimum rate, 50% for drugs and 10% for alcohol. PHMSA- and USCG-regulated employees should not to be placed in DOT random alcohol testing pools. Contact the appropriate DOT Agency for additional clarification.

[Please note that USCG covered employees may be combined with DOT covered employees in drug testing pools even though the USCG is now part of the Department of Homeland Security.]
