Log in to work
Actually... no.... This is a stupid mistranslation by the Highway Authority (Maatz), and what it really should say is "Entrance to work site." Unfortunately, our roads are full of mistranslations and misspellings like this one.
Well, maybe not unfortunately. It gives us bilingual people something about which we can laugh.
By the way, I am told that the sign is along Highway 75 in Northern Israel.
