Narrative:

I had requested progressive instructions to taxi at sac. Runway 30 was active. I thought I was told to taxi on north, cross runway 12 and hold short of runway 30. The controller and I went back and forth 3 times to get this straight. After crossing the runway 12 end of the runway, I stopped, as the instructions no longer made any sense to what I was now seeing. The controller then told me to stop and said I had just crossed the active. He said he had told me to taxi on north, hold short of runway 30 at the runway 12 numbers. After some conversation of the events, I asked for progressive again to taxi. There were no other planes taxiing at the time, no planes were in the pattern. Contributing factors: I taxied without fully understanding the instructions. I allowed the frustration in the controller's voice to keep me from questioning further. I assumed he would keep an eye on me as I had requested progressive instructions and the airport traffic was zero (no traffic) at the time. Corrective actions: I allowed my previous experiences with progressive instruction to influence my judgement. In the future, I will not taxi until I am sure of the directions and have plotted them on the taxi diagram.

Narrative: I HAD REQUESTED PROGRESSIVE INSTRUCTIONS TO TAXI AT SAC. RWY 30 WAS ACTIVE. I THOUGHT I WAS TOLD TO TAXI ON N, CROSS RWY 12 AND HOLD SHORT OF RWY 30. THE CTLR AND I WENT BACK AND FORTH 3 TIMES TO GET THIS STRAIGHT. AFTER XING THE RWY 12 END OF THE RWY, I STOPPED, AS THE INSTRUCTIONS NO LONGER MADE ANY SENSE TO WHAT I WAS NOW SEEING. THE CTLR THEN TOLD ME TO STOP AND SAID I HAD JUST CROSSED THE ACTIVE. HE SAID HE HAD TOLD ME TO TAXI ON N, HOLD SHORT OF RWY 30 AT THE RWY 12 NUMBERS. AFTER SOME CONVERSATION OF THE EVENTS, I ASKED FOR PROGRESSIVE AGAIN TO TAXI. THERE WERE NO OTHER PLANES TAXIING AT THE TIME, NO PLANES WERE IN THE PATTERN. CONTRIBUTING FACTORS: I TAXIED WITHOUT FULLY UNDERSTANDING THE INSTRUCTIONS. I ALLOWED THE FRUSTRATION IN THE CTLR'S VOICE TO KEEP ME FROM QUESTIONING FURTHER. I ASSUMED HE WOULD KEEP AN EYE ON ME AS I HAD REQUESTED PROGRESSIVE INSTRUCTIONS AND THE ARPT TFC WAS ZERO (NO TFC) AT THE TIME. CORRECTIVE ACTIONS: I ALLOWED MY PREVIOUS EXPERIENCES WITH PROGRESSIVE INSTRUCTION TO INFLUENCE MY JUDGEMENT. IN THE FUTURE, I WILL NOT TAXI UNTIL I AM SURE OF THE DIRECTIONS AND HAVE PLOTTED THEM ON THE TAXI DIAGRAM.
