What is unlawful to operate on a highway to prevent damage?

The response indicating that vehicles with studded or spiked wheels are unlawful to operate on a highway in order to prevent damage serves as the correct choice for this question. The reason for this is based on safety and road maintenance concerns. Studded or spiked wheels can cause significant wear and tear on road surfaces, especially in areas not accustomed to winter driving conditions where such features may be deemed necessary. Consequently, many jurisdictions regulate or prohibit their use to maintain the integrity of public roads and ensure the safety of all road users.

In contrast, vehicles with tinted windows, oversized tires, and standard headlights typically do not pose the same level of risk or damage to road surfaces. While there are regulations regarding these types of vehicles that may pertain to safety or visibility, they do not primarily relate to preventing physical damage to the highway itself.
