Narrative:

We were given a taxi clearance taxi to runway 25. In order to get to the taxiway which will bring you to the end of runway 25, you need to cross runway 25 about 1/4 of the way from the end of the runway. We were told to 'taxi to runway 25.' we proceeded across the active runway 25, to get to the taxiway which would bring us to the approach end of 25. We were the only aircraft moving on the airport at the time. We were told by ground control that we had crossed the active without clearance to do so. This is the only airport we operate into where you need to cross the active to get to the active. I know with that type of a clearance, you are cleared to cross all taxiways and runway with the exception of the active. I guess I put too much faith in the controllers to tell us to hold short of runways or taxiways. As pilots, we really need to rechk taxi clearance if were unsure of the controllers instructions. We also cannot depend on them to tell us to 'hold short.' I also feel controllers need to be more standardized on their instructions. I feel at times. They expect us to know what their intentions are without fully explaining themselves.

Title: CAPT OF LTT ACR ACFT CROSSED THE ACTIVE RWY DURING TAXI FOR TKOF WITHOUT ATC CLRNC.

Narrative: WE WERE GIVEN A TAXI CLRNC TAXI TO RWY 25. IN ORDER TO GET TO THE TAXIWAY WHICH WILL BRING YOU TO THE END OF RWY 25, YOU NEED TO CROSS RWY 25 ABOUT 1/4 OF THE WAY FROM THE END OF THE RWY. WE WERE TOLD TO 'TAXI TO RWY 25.' WE PROCEEDED ACROSS THE ACTIVE RWY 25, TO GET TO THE TAXIWAY WHICH WOULD BRING US TO THE APCH END OF 25. WE WERE THE ONLY ACFT MOVING ON THE ARPT AT THE TIME. WE WERE TOLD BY GND CTL THAT WE HAD CROSSED THE ACTIVE WITHOUT CLRNC TO DO SO. THIS IS THE ONLY ARPT WE OPERATE INTO WHERE YOU NEED TO CROSS THE ACTIVE TO GET TO THE ACTIVE. I KNOW WITH THAT TYPE OF A CLRNC, YOU ARE CLRED TO CROSS ALL TAXIWAYS AND RWY WITH THE EXCEPTION OF THE ACTIVE. I GUESS I PUT TOO MUCH FAITH IN THE CTLRS TO TELL US TO HOLD SHORT OF RWYS OR TAXIWAYS. AS PLTS, WE REALLY NEED TO RECHK TAXI CLRNC IF WERE UNSURE OF THE CTLRS INSTRUCTIONS. WE ALSO CANNOT DEPEND ON THEM TO TELL US TO 'HOLD SHORT.' I ALSO FEEL CTLRS NEED TO BE MORE STANDARDIZED ON THEIR INSTRUCTIONS. I FEEL AT TIMES. THEY EXPECT US TO KNOW WHAT THEIR INTENTIONS ARE WITHOUT FULLY EXPLAINING THEMSELVES.
