Narrative:

I landed on runway 23 at mbs. Because the runway is 8002 ft long and I intended to go to the FBO at the other end, I landed past the first taxiway and rolled out past the second taxiway. I was instructed to turn right onto taxiway B. This taxiway is just beyond runway 14/32 and goes off runway 23 at a 45 degree angle. The sign on runway 23 for taxiway B is just before runway 14/32 and, as I recall, points to the right at a 90 degree angle. I interpreted this to mean a right 90 degree turn at that point to taxiway B. When I made that turn, I realized I was on runway 32 instead of taxiway B. The controller advised that this 'would work' and that I should continue to the FBO. There is a sign part way down taxiway B for that taxiway, however, it is across runway 14/32 where it was not immediately evident to me. I would suggest that the sign for taxiway B that is on runway 23 have the arrow point at a 45 degree angle rather than a 90 degree angle. This may help to avoid confusion in the future.

Title: AFTER LNDG ON RWY 23 AT MBS ARPT, RPTR CLAIMS TXWY SIGN FOR TXWY B JUST BEFORE THE RWY 14-32 INTXN POINTS TO THE R AT A 90 DEG ANGLE WHICH IS CONFUSING.

Narrative: I LANDED ON RWY 23 AT MBS. BECAUSE THE RWY IS 8002 FT LONG AND I INTENDED TO GO TO THE FBO AT THE OTHER END, I LANDED PAST THE FIRST TXWY AND ROLLED OUT PAST THE SECOND TXWY. I WAS INSTRUCTED TO TURN R ONTO TXWY B. THIS TXWY IS JUST BEYOND RWY 14/32 AND GOES OFF RWY 23 AT A 45 DEG ANGLE. THE SIGN ON RWY 23 FOR TXWY B IS JUST BEFORE RWY 14/32 AND, AS I RECALL, POINTS TO THE R AT A 90 DEG ANGLE. I INTERPED THIS TO MEAN A R 90 DEG TURN AT THAT POINT TO TXWY B. WHEN I MADE THAT TURN, I REALIZED I WAS ON RWY 32 INSTEAD OF TXWY B. THE CTLR ADVISED THAT THIS 'WOULD WORK' AND THAT I SHOULD CONTINUE TO THE FBO. THERE IS A SIGN PART WAY DOWN TXWY B FOR THAT TXWY, HOWEVER, IT IS ACROSS RWY 14/32 WHERE IT WAS NOT IMMEDIATELY EVIDENT TO ME. I WOULD SUGGEST THAT THE SIGN FOR TXWY B THAT IS ON RWY 23 HAVE THE ARROW POINT AT A 45 DEG ANGLE RATHER THAN A 90 DEG ANGLE. THIS MAY HELP TO AVOID CONFUSION IN THE FUTURE.
