Morphology
The sense 'to overturn/capsize' is directly compositional from 'turn' (to rotate/flip) combined with 'turtle' given here as 'to overturn or capsize', so a learner who knows both constituent senses can derive the overall meaning. Although the verb 'turtle' is relatively rare in general vocabulary, the motion/result composition is literal and therefore transparent to someone who already knows the constituent definitions.
Etymology
The verb turn turtle likely comes from the image of a boat or vehicle flipping over like a turtle that has been turned onto its back, with its belly up. So today it means 'to overturn' or 'to flip over'.
