If you have a legitimate reason for carrying a scale in your vehicle, its not a problem. I carry a scale in my truck for weighing refrigerant cans.

If your just cruising around with a triple beam balance on the dash, thats kinda stoopid because your *ADVERTISING* to the world that something isn't quite right.

Do yourself a favor and keep all of the weed and paraphenalia out of the car. Don't put yourself in a position where somebody has to *DO* something about it.
