Electric Scooter Safety Instructional Poster Flat Vector Guide

Build the visual language around flat vector, choosing traffic blue, safety yellow, white, charcoal, and signal red for a distinct mood rather than a generic palette.

Make the design useful for the stated instructional poster context, with clear hierarchy, polished finish, readable shapes, and no distorted perspective, gibberish text, duplicate props, or accidental logo-like marks.
