We landed safely at OTH and turned right to exit the runway.  Tower informed us there were yellow chevrons on the pavement; meaning we were not authorized to taxi off of Runway 4 at that location. Tower then gave us taxi clearance to our gate.The chevrons; which lead up to the intersecting runway; were not easy to see.  There is pavement leading up to runway 13 that looks like a taxiway available for exit; but it actually leads up to the start of runway 13.I will confirm a turn off of the current runway onto an intersecting runway with ATC before the Captain initiates a turn.  I will brief this threat in the future; prior to landing in OTH. The intersection past A is not a taxiway; it is pavement leading up to a runway.
Poorly painted yellow chevrons are painted on the overrun. Not listed on Jeppesen plate as unusable. Shows up as gray on Jeppesen plate and looks like a taxiway. Closer examination shows that it ends at A - HS1 refers to taxiing on A.Should have rolled to the end of the runway and exited at the end instead of on the crossing runway. Jeppesen plate should note that runway 13/31 is not usable for taxi/takeoff or any operations past taxiway A.
After landing at OTH; an air crew turned off the runway at an unusable intersecting runway. Poorly painted yellow chevrons are painted on the overrun. Not listed on Jeppesen plate as unusable.
