There are posted signs that say “no overnight parking”.

Mid size Walmart parking lot near highway so expect road noise Street sweepers come through the parking lot around 5:30am but no one bothered me Few other cars stayed overnight Dispensary in the parking lot too if you're into that

Wouldn't recommend staying here, street sweepers woke us up at 7am by riding laps around all the parked cars while constantly honking for around 20 minutes.
