Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You didn't learn that reading with this kanji, so here's a mnemonic to help you:
Continue to think you're driving on this road. You hit something, then look behind you, seeing you hit a cow. Know the word for cow in Japanese? It's うし, which is also the reading for this word.
Please close the door behind you.
You must install the child carseat on the rear seat of the car.
If you turn around to look behind you and then do it again, you’ll see me.
