That's a head-smacker. Some guy somewhere must have actually painted that on the trailer - does that guy not think "Hey, this doesn't really make sense. Are you sure they didn't want somebody to translate this to Arabic?"

Or maybe he did and his boss told him to shut up and do as he's told. Or he thought - "Screw this, I wanna go home on time. I'm not gonna bother to find an Arabic translator now. I'll just paint exactly what it says, and they can't get me in much trouble for that."

Maybe he had a stencil and didn't speak english?

There's a certain schadenfreude to be had where the failed translation is also typo'd - but only once. These sorts of things are especially embarassing, as it not only shows no effort was used proofing, but nothing tripped a sanity check at all.
