What safety measure should be followed when traveling with an excavator on a public road?

Using a transport trailer is crucial when traveling with an excavator on a public road. This method ensures that the excavator is securely loaded and transported, minimizing the risk of accidents or damage. Transport trailers are designed to handle the weight and dimensions of heavy equipment, which is essential for safe road use. They provide a stable platform, often equipped with ramps or tie-down points to properly secure the excavator, preventing any shifting during transit.

Other methods, such as checking tire pressure or reducing speed, are important for safety but do not specifically address the proper means of transporting heavy equipment. While avoiding night travel might enhance visibility, it doesn't encompass the fundamental requirement for safely moving an excavator on public roads. Using a transport trailer identifies the primary and best practice for ensuring the excavator is safely managed while traveling, prioritizing the safety of both the equipment and other road users.
