What happens if a street rod has its hood or fenders removed?

The requirement that the engine fan must be enclosed with a shroud is designed to enhance safety. When a street rod has its hood or fenders removed, the engine and its components can become more exposed to the environment as well as to potential hazards, such as debris or even accidental contact.

An engine fan, being a moving part, poses a risk of injury if it is exposed. The use of an enclosed shroud serves to protect individuals from the rotating fan blades, reducing the risk of serious injury. Additionally, a shroud helps improve the efficiency of the cooling system by directing airflow over the engine and radiator. Ensuring that safety features like a fan shroud are equipped is essential, particularly in modified vehicles where the original design may have been altered.

While the other options present considerations regarding modifications or registration, they do not directly address the enhanced safety measures needed when components like the hood are missing. Thus, ensuring that moving parts such as the engine fan are safely enclosed fulfills a crucial role in maintaining vehicle safety and compliance with regulations.
