Driver turnover costs more than you think
Driver turnover costs more than you think
Fleet operations have high driver turnover relative to many other sectors. The American Trucking Associations documents commercial truck driver turnover at large carriers consistently above 90% annually — meaning the average driver tenure is less than 12 months.
The Society for Human Resource Management estimates the full cost of replacing a single employee at 50–200% of annual salary, depending on role complexity. For a skilled commercial driver, the higher end of that range applies.
For a driver earning the equivalent of $12,000 per year, full replacement cost is documented at $6,000–$24,000.
Fleet-specific turnover costs
- The productivity ramp-up period. Geotab telematics analysis of driver behaviour by tenure found that drivers in their first 90 days generate 34% more harsh events than the same organisation’s 12-month+ drivers — meaning more fuel consumption, more wear, and more incident risk.
- The safety risk period. Fleet Safety International research finds that accident rates for drivers in their first six months in a new role are 2.3x higher than the organisation-wide average.
- The training investment lost. Any organisation that has invested in driver training, behaviour coaching, or telematics-based performance improvement loses that investment when the driver leaves.
Driver retention is not just an HR outcome — it is a direct cost line. The cost of the programmes that improve retention (competitive pay, safety recognition, career development) is consistently lower than the documented cost of the turnover they prevent.
