Show the correct answer
Correct answer
A. Incorrect toe-in of the front wheels.
Explanation
In the photo, you are driving along a city street behind a dark car; on the right there are signs showing the lane layout and B-21 "no left turn". The cause of a car pulling to the left may be incorrect toe-in of the front wheels - answer A. Equal pressure in the tyres (B) is the correct state, and the handbrake module (C) has nothing to do with it.
Toe-in is the angle at which the front wheels are set in relation to each other, seen from above; in a car in good condition it is adjusted so that the wheels roll parallel to the direction of travel. When the toe-in goes out of adjustment after hitting a kerb or a pothole, the wheels "pull" in different directions, the car drifts to the side by itself, the steering wheel is crooked on a straight road, and the tyres wear unevenly and squeal on bends. Pulling can also be caused by a difference in tyre pressure or by a sticking brake on one wheel - so equal pressure is the opposite of the problem. The Road Traffic Act requires a vehicle to allow safe use of the steering controls, so you have the wheel alignment checked at a garage after every hard impact on a wheel and when the tyres wear unevenly.
