Which safety feature is shared by both platform and ground controls?

• A. Emergency stop and interlocks
• B. GPS location tracking
• C. Automatic braking
• D. Overhead camera

Answer: (A)

Safety systems that work from both the operator platform and the ground control are designed so a halt can be triggered from either location and so operations can’t proceed unless all safety conditions are met. The emergency stop and interlocks fit this role perfectly: the emergency stop immediately cuts power and stops all motion no matter which control station issued the command, and interlocks prevent the machine from moving or being operated unless required safety conditions are satisfied (such as doors closed, outriggers deployed, or guards engaged). Having these features shared across both controls ensures a consistent, reliable safety response no matter where the control happens to be.

GPS location tracking, automatic braking, and overhead cameras are useful tools in various contexts, but they aren’t universal safety mechanisms shared by both control points in the way emergency stop and interlocks are.
