Correct answer
B. An improper wheel alignment.
Explanation
In the photo a white car is driving in the right-hand lane of a high-speed road with its brake lights on, pointing diagonally to the left, as if it were being pulled off its path. A vehicle "pulling" to the left while going straight on may be caused by incorrect wheel alignment (toe) - answer B. Power steering (A) does not pull the car to the side, and too low a pressure in the right front tyre (C) would pull it to the right, not to the left.
Toe is the angle at which the wheels are set in relation to the axis of the car; when it is out of adjustment, for example after hitting a kerb or a pothole, the wheels roll slightly "at an angle", the car turns to one side by itself and the tyres wear unevenly. This symptom can also be caused by uneven tyre pressure or damaged suspension. The Road Traffic Act requires the vehicle to be kept in such a condition that it does not endanger safety, and the Regulation on the technical conditions of vehicles requires the steering system to allow an easy and safe change of direction. If you have to correct your path all the time, check the tyre pressure, and then have the wheel alignment set.
Legal basis: Art. 66 para. 1 point 1 of the Road Traffic Act (Prawo o ruchu drogowym); § 9 para. 1b of the Regulation on the technical conditions of vehicles and the scope of their necessary equipment
