The solo student pilot reported that during the landing roll, she used brakes and pulled back on the yoke, but the airplane was traveling too fast to turn off at the taxi intersection she normally used. She became confused as to where to turn off the runway, turned left toward the next taxiway intersection too fast, but the airplane exited the runway to the left and struck a taxiway sign.
The airplane sustained substantial damage to the engine mount.
The student pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
The airport's automated weather observation station reported that, about 3 minutes after the accident, the wind was from 230° at 4 knots. The student pilot landed the airplane on runway 28.
