The best measure to assess a stop sign is its visibility, which can be quantified by factors such as size, color contrast, and placement. Standard dimensions for a stop sign are typically 30 inches (76 cm) in diameter for regulatory signs. Additionally, measuring the height of the sign from the ground ensures it is easily seen by drivers. Reflective materials can also be evaluated to determine how well the sign stands out at night or in low-light conditions.
