While overtaking, should you be more alert and adjust how you drive to match shifting road conditions and scenarios, ensuring you can react swiftly?

Yes. Overtaking is one of the most dangerous manoeuvres on the road and calls for extra care. Under art. 24 para. 2 of the Road Traffic Act, a driver must make sure that conditions allow the manoeuvre to be carried out safely, and that means watching the changing road situation the whole time.
