PIPER PA28 WARRIOR PVT PLT INADVERTENTLY CROSSED THE ACTIVE RWY DURING TAXI OUT DUE TO MISINTERP OF TAXI CLRNC.

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.
