Here is a simple explanation of what makes this model special and how it is designed:

1. The Overall Concept This asset is a mobile traffic trailer used to guide cars away from roadworks or accidents. It is designed to be towed behind a truck and set up quickly on the highway to keep workers safe.

2. Bright LED Arrow Display The most important feature is the large rectangular board covered in small amber lights. In the image, these lights are turned on to form a bright Left Arrow shape, clearly telling drivers to merge into the next lane.

3. Safety Orange Frame The entire metal body of the trailer is painted a high-visibility safety orange. This ensures that the equipment stands out against the grey road, even when the lights are turned off during the day.

4. Stabilizer Jacks At each corner of the trailer, there are extendable metal legs (jacks) resting on the ground. These are used to lift the wheels slightly and keep the sign steady so it doesn't roll away or tip over in the wind.

5. Detailed Towing Hitch The front of the trailer features a realistic towing mechanism, including a metal coupler to attach to a truck, safety chains, and a small jockey wheel used to move the trailer by hand when it is unhitched.

Files Included: FBX, GLB, OBJ, STL, ZIP (Textures). Quick Tip: The LED Board uses a grid texture. By changing the Emissive Map (the glowing part of the texture), you can easily change the arrow to point right, show a Caution bar, or make the lights flash in a sequence.
