It's a reminder from OPP to keep your vehicle locked, and your keys on you.
The notice comes as OPP report 21 vehicles have been stolen so far in Huron County this year.
Of the vehicles report stolen, fourteen had the keys inside.
Three of those cases involved the vehicles left unattended with the engine running and the doors unlocked.
Police recommended locking your car or truck, rolling the windows up, parking in a well-lit area, and keeping valuable items out of view of would-be thieves.
