What is a control point in vehicle measurement?

• A. A specific location on the vehicle used for accurate measuring.
• B. A point on the frame where welding must occur.
• C. A tool used to pull damaged panels back to shape.
• D. The vehicle's door hinge location.

Answer: (A)

A control point is a specific, fixed spot on the vehicle used as a reference for accurate measuring. These points provide stable coordinates so you can compare actual measurements to the manufacturer’s specifications and determine how far the frame or body is out of alignment. They’re chosen because they don’t shift during the repair process and are documented in repair diagrams for consistent measurement across the vehicle.

The other ideas describe repair actions rather than measurement references. A welding point on the frame is where repair work is done, not where measurements are anchored. A pulling tool is used to reshape panels, not to establish reference positions. The door hinge location is a feature of the vehicle, not a standardized measurement reference used in alignment checks.
