For answer  A 

You are obliged to drive at a speed that does not exceed 30 km/h in the urban area, or 50 km/h outside the urban area, in particularly dangerous curves signalled as such or in which visibility is less than 50 metres. And if the agricultural or forestry tractor you are driving has a trailer attached you will reduce speed in time (before the curve), because the danger of the trailer skidding is very high. Driving through a curve is done with reduced and constant speed, and only after exiting the curve, when visibility is good, you may accelerate.

For answer  B 

When you reach the apex of the curve, meaning in its middle, it is NOT the right moment to accelerate. The right moment to accelerate is right after exiting the curve, when you also have the best visibility.

For answer  C 

It is not recommended to brake inside the curve, braking is done before the curve. If you brake inside the curve, the trailer will tend to move straight ahead and the phenomenon of the trailer oversteering appears.

The correct answer is: A
