Many driver incentive strategies are being deployed by fleets to improve fuel economy and driver retention. Drivers can receive pay bonuses, per-mile pay increases, or prizes for attaining predefined fleet-wide efficiency goals or out-achieving other drivers. Driver retention improves fuel economy increasing the effectiveness of almost all fuel efficiency technologies as the drivers are comfortable and trained in the specific equipment bought by that fleet. For fleets with low driver turnover, the value of driver training is improved since the drivers trained stay with the fleet.
