In three to five sentences identify two components of the control substances of vehicle and use them to explain why driving can be hazardous when the control subsystem is not functioning properly

Two components of the control subsystem of a vehicle are the steering system and the braking system.

When the steering system is not functioning properly, the driver may have difficulty maintaining control of the vehicle, leading to swerving or veering off course.
Similarly, if the braking system is not working correctly, the driver may not be able to stop the vehicle in time to avoid a collision or obstacle in the road.
Overall, a malfunction in either of these components can greatly increase the risk of accidents and make driving hazardous.
