Yes, you worked very hard to get your license, and it’s immeasurably precious to you, but that doesn’t mean you can lock it up in a safety deposit box or hang it on your living room wall beneath two inches of glass. You’ll need to keep your license on your person (that means you—we highly doubt you own a person, and if you do, we should talk) at all times. This way, you can show it to the nice policeman who pulls you over for going 80 in a 45, or to the not-so-nice gentleman whose Lexus you hit when doing the same.
