A flatbed container trailer equipped with mud guards has several advantages:

1. Protection from debris: Mud guards prevent debris such as rocks, gravel, and dirt from flying off the trailer and potentially damaging other vehicles on the road or causing accidents.

2. Improved visibility: Mud guards can help improve visibility for other drivers by reducing the amount of spray and mist that is kicked up from the tri axle flatbed container trailer in wet weather conditions.

3. Reduced maintenance costs: Mud guards can help reduce maintenance costs by protecting the tri axle flatbed container trailer's wheels and undercarriage from corrosion, rust, and damage caused by road debris.

4. Compliance with regulations: In some jurisdictions, tri axle flatbed container trailers are required by law to have mud guards or similar devices to prevent debris from being thrown onto the road.

Overall, mud guards are a simple yet effective safety feature that can help protect both the 40 feet tri axle flatbed container trailers and other vehicles on the road, while also reducing maintenance costs and ensuring compliance with regulations.
