We use the ROO SHOO on the front of our vehicle. It is like a little silver whistle that gives off a high pitched sound as the wind blows through it. They are terrific and affordable. We bought ours at Supercheap. They not only save the wildlife, they can avoid a nasty accident and I feel safer with one on my vehicle especially when driving at night.

Really? How do they actually work?

were lucky we dont have many kangaroos here.

can you use your horn
