The tower had not yet opened; but I observed a fuel truck crossing the active Runway 21L at Taxiway D3. There was a GA aircraft on departure roll; abeam Taxiway D5. After the GA aircraft got airborne; the pilot said; 'Fuel truck; you need to look before you get on a runway; I was departing.' The worst part is; the vehicle should never have been there; as there are loop roads to avoid the runways available to the driver.I did not say anything; as we were not yet legally open. Reeducate the driver; or fire him.
PRC Tower Controller reported a fuel truck crossed the runway as an aircraft was departing before the Tower opened.
