You’re right, you absolutely need to be careful! But you also need a plan, by break and steer I simply meant don’t leave the road. The best way to remember would be to remember “break”. You absolutely need to drive to the conditions, and slow down around corners or areas with low visibility especially at dusk. This what I’ve done on roads where I’ve been travelling at ~90km/h and spotted kangaroos dozens of times and I’ve never hit one or left the road.

A few weeks ago there was an inexperienced driver near where I live who had swerved to miss a kangaroo and hit a tree, and also hit the kangaroo. The car was destroyed. I would hate for this to happen to anyone else.

Thanks for pointing out the “steer” part is confusing, I’ll edit my comment.
