There are times when I am running out the door, but I remember that I may have forgotten to lock one of my doors. Nearly 3/4 of the time, I did lock it but I have to waste time going back and checking. I can see the lock from where I leave from, but I can't make out the details of if it is turned or not. Is there any hack for checking if a door is locked just by looking?
This is the type of lock that I have (its a deadbolt I believe)
