Narrative:

During an IOE training flight, tower advised us after landing, traffic behind was on 1 mi final, no delay to the end of runway. Observing that my trainee was not taxiing fast enough to clear runway 8 in time for landing traffic, I instructed him to turn on taxiway and hold short of runway 11. This taxiway was closer and we cleared in time. Tower advised us that we were now on both runways. This was confusing, as we appeared to be within the hold short lines. Both aircraft on runways 11 and 8 were instructed to go around. Tower then cleared us to taxi. I believe that while traffic spacing was a factor, I feel that the confusing airport markings were to blame. This would be an even easier mistake for a private pilot in a small aircraft that would even more easily fit between the lines.

Title: SMT IOE INSTRUCTOR PLT TURNED OFF RWY 8 ONTO TXWY G. THE CREW WAS CONFUSED BY THE HOLD SHORT MARKINGS.

Narrative: DURING AN IOE TRAINING FLT, TWR ADVISED US AFTER LNDG, TFC BEHIND WAS ON 1 MI FINAL, NO DELAY TO THE END OF RWY. OBSERVING THAT MY TRAINEE WAS NOT TAXIING FAST ENOUGH TO CLR RWY 8 IN TIME FOR LNDG TFC, I INSTRUCTED HIM TO TURN ON TXWY AND HOLD SHORT OF RWY 11. THIS TXWY WAS CLOSER AND WE CLRED IN TIME. TWR ADVISED US THAT WE WERE NOW ON BOTH RWYS. THIS WAS CONFUSING, AS WE APPEARED TO BE WITHIN THE HOLD SHORT LINES. BOTH ACFT ON RWYS 11 AND 8 WERE INSTRUCTED TO GO AROUND. TWR THEN CLRED US TO TAXI. I BELIEVE THAT WHILE TFC SPACING WAS A FACTOR, I FEEL THAT THE CONFUSING ARPT MARKINGS WERE TO BLAME. THIS WOULD BE AN EVEN EASIER MISTAKE FOR A PVT PLT IN A SMALL ACFT THAT WOULD EVEN MORE EASILY FIT BTWN THE LINES.
