* Loss of control: The frame is what holds all the other components together. A break can affect steering, braking, and suspension, making the car difficult or impossible to control.
* Rollover: A weakened frame is much more susceptible to rolling over, especially in turns or during accidents.
* Severe injury or death: In a collision, a broken frame offers little protection to the occupants. The car is likely to crush more easily.
Driving a car with a broken frame is incredibly unsafe and illegal. The vehicle should be towed to a repair shop for assessment and repair (or potentially scrapping, depending on the severity of the damage).
