What happens to the car when the rear tire blows?

When a rear tire blows out, the loss of air pressure can lead to a significant change in the car's handling dynamics. The correct answer highlights that the car is likely to sway back and forth, which occurs because the blown tire can affect the vehicle's balance. This instability is particularly noticeable in rear-wheel drive vehicles, where the sudden loss of control in the rear can cause the car to steer or pivot uncontrollably.

Drivers may experience a noticeable change in the vehicle's tracking, leading to difficulties in maintaining a straight path. This sway can increase the risk of losing control, especially if the driver reacts abruptly. Understanding this behavior is crucial for drivers to safely manage a sudden tire blowout by maintaining a steady grip on the steering wheel, easing off the gas, and pulling over safely to the side of the road.

The other options describe effects that do not typically happen immediately during a blowout. A stable car would not accurately represent the situation, while the loud noise and unexpected acceleration are less direct consequences of a rear tire failure compared to the swaying that results from loss of traction.
