Final answer:
When reacting to a hazard, a driver can change the car's speed and/or change its direction.
Step-by-step explanation:
The statement is true. When reacting to a hazard, there are generally two options for a driver: changing the car's speed and changing its direction.
Changing the car's speed involves accelerating or decelerating, which can help the driver either avoid the hazard or reduce the impact if a collision is inevitable.
Changing the car's direction involves steering, which allows the driver to maneuver around the hazard or change lanes to avoid it.
