What type of vehicles must meet the mechanical and roadworthiness standards for airside driving?

Specialist airside vehicles must meet the mechanical and roadworthiness standards for airside driving because these vehicles are specifically designed for operations in airport environments. This includes vehicles like baggage tugs, fuel trucks, and maintenance vehicles that require specialized features to operate safely and effectively on the airside. Ensuring these vehicles are mechanically sound and roadworthy is crucial for maintaining air safety and preventing accidents in high-traffic areas where aircraft and other ground services operate.

In contrast, options like personal cars or government-owned vehicles may not be subject to the same stringent standards for airside operations, as they are not intended for use in the specialized conditions present at airports. Similarly, standard vehicles might be included in general traffic regulations but would lack the specific adaptations that specialist airside vehicles possess, making them less relevant in this context.
