With respect to turns, what is true about a car's rear wheels?

The correct choice highlights that a car's rear wheels have a smaller turning radius than the front wheels. This is due to the design and mechanics of vehicle turning. When a vehicle makes a turn, the front wheels lead the direction of the turn, pivoting around a point that is located near the front axle.

The rear wheels, on the other hand, follow a curved path that is adjusted based on the angle of the front wheels. Since the rear wheels are positioned further back from the front, they effectively travel along a different radius, which is narrower than that of the front wheels. This characteristic is particularly important in maneuvering, as it allows the car to navigate tighter spaces and make sharper turns than if all wheels were constrained to the same radius.

As for the other statements, the first suggests that the rear wheels have a longer turning radius, which contradicts the fundamental mechanics of turning. The third statement implies that the rear wheels play no role in the vehicle's turning, which is incorrect since they do follow the turn but at a different radius. The last statement claims that the rear wheels turn at the same radius as the front wheels, which is also inaccurate for the reasons explained above. Understanding this aspect of vehicle dynamics is crucial for driving instructors
