Which statement about side vision is true?

• A. It allows you to see somewhat what is happening on either side of your vehicle.
• B. It helps you judge distances to other cars.
• C. It improves your reaction time to hazards in front.
• D. It signals when to stop.

Answer: (A)

Side vision, or peripheral vision, is the ability to notice movement and objects to the sides of your vehicle without turning your eyes toward them. That’s why the statement is true: you can see somewhat what’s happening on either side of your car, which helps you stay aware of lane changes, pedestrians near the curb, or bikes entering your blind spots.

But peripheral vision isn’t precise for judging exact distances to other cars—that relies on central vision and depth cues you actively estimate. It also isn’t the main tool for spotting hazards straight ahead, which requires looking forward with focused vision. And while overall awareness and safe braking determine when you stop, side vision alone doesn’t directly tell you when to stop.
