Downtime Truism: If the Wheels Don't Turn, You Don't Earn

WORK TRUCK's June article on how Mike Antich sees the effects of vehicle downtime on vehicle earnings 

     One of the perks of my job is getting to know truck professionals from around

the world. An example is Hugh Sutherland, one of the foremost fleet experts in South Africa from whom I first heard the phrase: “If the wheels don’t turn, you don’t earn.” This pithy truism succinctly captures the essence of truck fleet management. Work trucks are earning assets. To maximize truck productivity, optimize specifications, operating procedures, replacement strategies, and, just as important, minimize unscheduled downtime. The cost of unscheduled vehicle downtime can vary, but I’ve read reports that document the average per vehicle downtime costs ranging from $448 to $760 (R6 700 to R11 400) a day.

A multi-pronged vehicle downtime mitigation program is key to maximizing vehicle uptime, such as a proactive PM program and a planned vehicle replacement schedule.

     Vehicle downtime is a universal phenomenon that impacts all fleets — both good and bad fleets. What is manageable is the frequency of downtime; however, there is no industry consensus on the definition of “downtime.” Is downtime for all repair events or only for unscheduled events? Similarly, metrics to track downtime vary by company. Downtime metrics can be the average downtime hours per day, days of downtime per event, vehicle downtime per month, total downtime hours, or a metric specific to an operation.

The two most common causes of unscheduled downtime are mechanical problems and accidents. Other causes of unscheduled downtime include:

   • Recalls that sideline a vehicle until the required modifications or repairs are made.

   • Expired tags/registration.

   • Registration renewal denied due to unpaid tolls, parking tickets, or moving                      violations.

   • Extreme weather damage to a vehicle.

   • Emergency road service for lockout, dead battery, or flat tire.


Some vehicle downtime is scheduled and predictable to comply with scheduled

PM. Likewise, driver downtime can result from company-required attendance to sales meetings, conferences, or additional training.

Measuring the Hard and Soft Costs of Downtime

When a breakdown happens on the road, there are towing costs, labour for emergency repairs, and delays in delivering a product or service to the customer.

However, there’s more to vehicle downtime costs than service, repairs, and part

replacement expenses. Other costs associated with vehicle downtime include:

  • Lost vehicle revenue opportunity per day.

  • Costs associated with the loss of a driver’s productive time.

  • Costs imposed as a penalty when a load or service is not delivered or performed on time.

In addition, unexpected vehicle downtime caused by mechanical issues or accidents will have ramifications on your fleet’s productivity. When a vehicle breaks down, or needs repair due to an accident, drivers must spend time dealing with it, and that is time away from customers. When you can’t meet your targets and deadlines because you have a fleet truck that is unavailable, your business will suffer. When drivers are not able to work due to a vehicle problem, they cannot produce revenue. Time in the shop, instead of on the road, means lost sales and less face time with customers, putting downward pressure on the bottom line. Until a driver is back on the road, downtime will cause a company to incur both hard and soft expenses that can siphon thousands of dollars from a fleet’s budget.

Strategies to Reduce Downtime

Downtime mitigation is key to controlling costs and helping to maximize fleet uptime. The best ways to minimize vehicle downtime is with a proactive PM maintenance program, training drivers to practice safe driving behaviours, and keeping vehicles in the best condition possible with planned component repairs and driver inspections. The vehicle operator is the first line of defence against unexpected breakdowns and repairs.

 Another important strategy to mitigate downtime is to have a planned vehicle replacement schedule to minimize the increased frequency of age-related vehicle downtime.

     Even trucks that provide years of reliable service are ultimately destined to be financial liabilities sooner or later. Long-in-the-tooth trucks typically need repairs that require longer turnaround times, resulting in longer driver downtime, and are more expensive to return to service. By continually bringing newer vehicles into the fleet, you can slowly phase out older, more trouble prone vehicles that will keep downtime and performance issues to a minimum.


     Remember, if you keep the wheels turning, you’ll keep on earning.
