Final answer:
Drivers should look ahead 12 to 15 seconds while driving, which helps in recognizing and responding to potential hazards, leading to safer driving practices.
Step-by-step explanation:
The correct answer to the question of how far ahead drivers should look while driving is B. 12 to 15 seconds. This range of time is recommended as it allows the driver enough time to recognize and respond to hazards on the road, including the changing positions of other vehicles.
For example, if you are driving and hear a Doppler shift in an ambulance siren, this knowledge can assist you in deciding when to pull over.
Similarly, understanding vehicle speeds, like how Bridget measures cars traveling between two poles, can also inform safe driving practices.
Furthermore, having the reaction time to notice when leading vehicles hit their brakes or to understand stopping distances in different conditions, as shown in Figure 2.34, is crucial for maintaining safety on the road. Knowing these details helps prevent accidents and ensures a safe driving experience for everyone on the road.
