Many trucking companies measure turnover as their primary gauge of retention success. While it’s an important indicator, turnover alone doesn’t tell the full story of driver satisfaction or the overall health of your company culture.
Relying solely on turnover rates can hide deeper issues, such as engagement, communication, and growth opportunities, which can all influence why your drivers stay or leave.
If you want to build a truly sustainable retention strategy, it’s time to track metrics that go beyond basic numbers. Here are five key retention metrics that reveal the real drivers of long-term success.
Retention Rate
Retention rate may sound like the flip side of turnover, but it paints a more optimistic and actionable picture. Instead of counting who left, retention focuses on who stayed and for how long.
How to measure it: Divide the number of drivers who remain employed over a certain period (such as one year) by the number of drivers employed at the start of that period.
Why it matters: Tracking retention rate over time helps you understand which efforts, like pay adjustments, home time improvements, or communication initiatives, are keeping drivers engaged. For example, if your retention rate improves after introducing a driver mentor program, you’ll have measurable proof that the program is working.
Early Tenure Turnover
Turnover within the first 90 days is often the most expensive and disruptive kind. Early tenure turnover also shows how well your onboarding and orientation processes are working.
How to measure it: Track how many drivers leave within their first 30, 60, or 90 days compared to your total new hires during the same time frame.
Why it matters: If you’re seeing high early turnover, it might not be the job itself that’s the problem, but the transition into it. New drivers often leave because of unclear expectations, poor communication, or a lack of connection with dispatch. Improving onboarding communication, assigning mentors, or setting clear performance goals can make a measurable difference in this metric.
Average Tenure
Average tenure gives insight into how long your drivers stay with your company overall. It’s a simple but powerful measure of satisfaction and stability.
How to measure it: Add up the total length of employment for all drivers and divide by the total number of drivers. You can also break this down by department, region, or role type (for example, regional vs. OTR).
Why it matters: Companies with longer average tenure often have stronger communication, consistent scheduling, and leadership that listens. Tracking average tenure helps identify where long-term relationships are thriving, and where they may be breaking down. If one terminal or region consistently shows shorter tenure, that’s a sign to dig deeper into its management structure, workload, or overall culture.
Driver Engagement and Satisfaction Scores
While harder to quantify than turnover, engagement scores provide direct insight into how drivers feel about their work environment, leadership, and communication with dispatch. Regular driver satisfaction surveys and other opportunities for feedback can help you measure engagement trends over time.
How to measure it: Use brief, anonymous surveys that ask drivers to rate their satisfaction in areas such as pay transparency, home time, respect from management, communication, and recognition. Calculate an average score or index from these results.
Why it matters: Engagement and satisfaction scores reveal the “why” behind turnover and retention rates. They also give drivers a voice, showing that your company values their feedback. If your engagement scores start to dip, it’s an early signal to act before turnover increases.
Referral Rate
When drivers are recommending your company to their peers, it’s one of the clearest signs of a healthy, positive culture. Tracking referral rate helps measure trust, satisfaction, and pride in your company.
How to measure it: Track the percentage of new hires who were referred by current drivers over a given period.
Why it matters: A high referral rate often means drivers feel valued, respected, and confident enough to encourage others to join. If referrals drop, it may signal dissatisfaction or communication gaps. Consider implementing a referral incentive program, but just be sure to remember that incentives alone won’t raise this number unless drivers genuinely enjoy working for your carrier.
Putting It All Together
The most effective retention strategies come from looking at these metrics together, not in isolation. A company might have a solid overall retention rate but a worrying 90-day turnover trend, suggesting that onboarding needs improvement. Or a fleet may show long driver tenure but low engagement scores, signaling burnout or lack of advancement opportunities.
To make these metrics meaningful, be sure to track them consistently and discuss results across departments. Encourage dispatch, safety, and HR teams to use the data collaboratively. When patterns emerge, it’s essential to act quickly, whether that means improving communication tools, adjusting scheduling, or offering more training opportunities.
