Case Study: McKenzie Tank Lines achieves 20% reduction in critical events and nine months rollover-free with Omnitracs Critical Event Reporting

McKenzie Tank Lines Reduces Rollover Crashes with CER Service

McKenzie Tank Lines, a Tallahassee-based hauler of hazardous chemicals and petroleum with about 400 tractors and 1,000 trailers, faced high accident liability and inefficient, one-size-fits-all driver training—with rollovers costing at least $150,000 and potentially up to $1 million when injuries or spills occur. The company needed better visibility into risky driving to reduce liability, prevent environmental damage, and ensure safer deliveries.

By deploying Omnitracs’ Critical Event Reporting (CER) for near‑real‑time monitoring of hard braking and stability-control events, McKenzie could “manage by exception,” identify high‑risk drivers, and deliver targeted training. The program drove a 20% reduction in critical events, produced nine months without a rollover after implementation (vs. three rollovers the prior year), cut exposure to product loss and liability, and strengthened the company’s safety reputation.
