Underwrite this in replacement hires avoided, using your own numbers. Take your current annual driver turnover count, put your real cost on each replacement - recruiting, licensing, training, and the weeks before a new driver runs a lane cleanly - and that is the recurring bill you are trying to shrink. If earlier intervention keeps even a modest share of the drivers who would have quit, the system covers itself; every retained driver after that is margin. The operational gains ride along: experienced drivers who stay hold OTDR up, generate fewer detention disputes, and cost you less emergency expedited freight.
The return compounds over the first year. Early months show intervention successes on the most obvious high-risk, high-impact drivers - the HAZMAT-certified operators and critical-lane performers you least want to lose. As the model retrains monthly on your actual turnover outcomes, it learns which retention levers work on your lanes and your driver demographics - fuel surcharge adjustments here, schedule flexibility there - and stops recommending the ones that don't. Recruitment spend falls as a trailing effect, not a promise: fewer departures simply means fewer seats to fill.
