Is water dripping from the car AC normal?

Water dripping from an air conditioner is usually normal condensation functioning as intended, but it can sometimes indicate an issue depending on where it originates or if it follows an impact like hitting a road hazard. Knowing whether it is standard condensation or a leak prevents unnecessary anxiety and helps determine if a drain plug needs attention.

I noticed it dripping water after arriving home yesterday. I see there’s a drain plug, do I need to pull it to let it fully drain or is this functioning as it was intended?source ↗

Accidentally drove over a cinderblock today. This has been dripping under my 2022 Honda CRV since. I’m assuming it’s the AC line but would love it if someone could ease my anxiety.source ↗
