Case Study: KLLM improves driver safety and hiring quality with Psychemedics hair drug testing

KLLM cuts drug-test positives from 14%-15% to 6%-7% with Psychemedics

KLLM, a major refrigerated carrier, sought to create a safer, drug-free fleet of drivers. As a member of the Trucking Alliance, their challenge was to improve the quality of their hires and reduce safety incidents by deterring drug users from applying. To address this, they partnered with Psychemedics Corporation to implement the vendor's hair testing service into their pre-employment screening process.

Psychemedics' hair testing solution immediately identified a significant number of drug users, with initial positive rates of 14-20%. The results served as a powerful deterrent; once the test was communicated upfront to applicants, many drug users opted out of the process. This improved the quality of the hiring pipeline, reduced wasted recruiting costs, and helped KLLM avoid costly hiring mistakes. The positive test rate fell to 6-7% within a year, and the program had no negative long-term impact on staffing.
