In applying the horizontal angle of incidence, which principle is described?

• A. Slice the pie search around the vehicle
• B. Go around the corner around the window
• C. Suspect would have to rise to see you
• D. Do not bounce over the window

Answer: (A)

Approaching a vehicle with safety and awareness means sweeping all the angles around it in a systematic way. The horizontal angle of incidence is about how your line of sight changes as you move laterally around the vehicle so you don’t miss anything hidden in blind spots. By slicing the pie, you step around the vehicle in small angular steps, pausing to clear each sector—from front to sides to back—so you can see into windows, around mirrors, and into door gaps. This pattern gives you a complete, organized scan and keeps you prepared for any occupants who might be concealed. Other movements that don’t involve this deliberate angular sweep—like just circling to one side or peeking at a single window—don’t guarantee coverage of all possible hiding spots and can leave you exposed.
