A mid-sized trucking company with 120 CDL drivers faced significant downtime sending drivers to off-site clinics for DOT physicals. We implemented a quarterly on-site testing program at their terminal, conducting 120 physicals over three days with same-day medical certificate issuance. Result: 95% reduction in driver downtime, $18,000 annual savings in lost productivity, and 100% compliance rate maintained for 18 consecutive months.
