Final answer:
True. Directional control refers to a vehicle's ability to maintain a straight path or a chosen direction, which is essential for safety. Features like cruise control aid in keeping a steady speed, while friction between tires and the road is vital for turns.
Step-by-step explanation:
Directional control is indeed a vehicle's ability to hold a straight line or to continue in a particular direction. This is a critical aspect of vehicle dynamics and is essential for safe driving conditions. When a car is moving on a straight road at a constant speed in a single direction, it is exhibiting directional control. Functions such as cruise control are designed to assist in maintaining this steady motion when driving. Additionally, in the context of motion, directional control relates to the ability to follow a planned path, such as when following directions that involve movement to the east and then to the north.
Correct vehicle handling and directional control also involve the concept of friction between the tires and the road, which is crucial when a car turns on a curve. Without sufficient friction, the car would not be able to safely maintain its path of motion.
