Australia uses what are called road trains, which essentially is 3 full sized semi-trailer loads pulled by a massive single cab travelling 90km/h. A good place to find them are the highways between Adelaide and Perth or Adelaide and Darwin. At night, their stopping distance is greater than their headlights can reach; if they see something, it is too late to stop and the choice is swerving and likely tipping or plowing on through. This is why they have bull bars on the front (you might know them as cow catchers), so when there is a herd of cows on the road staring you down the cab can plow straight through without slowing.

(or maybe tech has caught up in the last few decades and they detect obstructions from further away, but that would spoil the story)
