For heavy-duty trucks, driving style is generally acknowledged to be the single greatest influence on vehicle fuel performance. Various studies have estimated that regular training in fuel-efficient driving techniques can yield fuel savings up to 15%- 20% per vkm. A British study found trained drivers were 6% more fuel-efficient than untrained drivers.
Relatively few drivers receive proper training on a regular basis. Constant reminders to drivers and regular feedback on performance are valuable tools for improving driver performance. Several emerging information technologies also may help drivers boost efficiency:
