How Can You Pass the Tree

A car is on a narrow road with a tree in the middle of it. How can the car pass the tree?

The tree is in the middle of the road as measured by length, not in the middle of it by width. In other words, the tree is growing on the side of the road, but it is equidistant from either end of the road, and therefore in the middle.

This makes it quite easy to pass the tree as you just drive on the road, unless you’re texting and you run into said tree. If this is the case, stop texting.

Thanks to everyone’s input on this one!

I haven’t figured this out yet. Bad apple doesn’t really fit with the lowercase letters. They’re both vowels, but I don’t know if that’s relevant. The fourth one looks kind of like a hill, could it be apple hill?
