This guide provides fleet managers with a comprehensive, structured framework for evaluating and comparing AI dash cam providers through a fair, side-by-side trial. With 44,000 traffic fatalities in 2023 and the average cost of a fatal commercial accident reaching $3.6 million, selecting the right dash cam technology is a critical business decision. The guide walks through five key steps: defining success metrics, identifying unsafe driver behaviors, setting up a controlled test environment, running the trial, and analyzing results using provided templates. By controlling variables such as camera placement, lighting conditions, and hardware condition, fleets can make an objective, data-driven decision that could save lives and significantly reduce financial risk.
