You are riding a motorcycle. What danger should you expect when passing an oncoming bus?
Explanation
Correct answer: A gust of wind first towards the right edge of the road and then towards the middle.
When passing a large vehicle such as a bus, a motorcyclist must take into account aerodynamic phenomena. Initially, the mass of air pushed by the front of the bus will force the light motorcycle to the right, and then, after passing the cab, a zone of lower pressure (the so-called aerodynamic shadow) will suddenly "pull" it towards the centre of the roadway.
