Human Factors; Procedure
On landing rollout [Runway 28] I assumed control of the aircraft and we both heard Tower direct us to exit at Runway 20 (I could make it safely). I started to make the turn and immediately saw a light aircraft landing on Runway 20. I immediately corrected the aircraft track back on Runway 28 and immediately requested taxi clarification. It was a directive NOT to enter Runway 20 (in broken English). Both of us where shaking about the possible outcome if we had made that turn. I made the next turn off and held short of Runway 20 as directed by MMGL Tower. While looking back at the contributing factors; I am convinced this incident was due to stress directly related to [company issues].
After landing Runway 28 at MMGL; an Air Carrier flight crew believes they heard an ATC clearance to exit on Runway 20. In fact; it is a clearance not to enter Runway 20 as a light aircraft is landing.
