Which vehicles are typically not permitted during aircraft operations?

Non-essential vehicles are typically not permitted during aircraft operations because they do not contribute directly to the safety, efficiency, or necessary functioning of airport activities at that time. During critical phases of flight, such as takeoff and landing, it is essential to minimize the presence of any vehicles that could create safety hazards or distractions. Non-essential vehicles do not fall within the scope of operations that are crucial for maintaining airport safety protocols, and therefore, their presence is restricted.

In contrast, emergency vehicles are allowed to be present as they are vital for responding to incidents and ensuring the safety of operations. Essential service vehicles, which are necessary for the day-to-day operations of the airport, are also permitted since they support operational needs. Maintenance vehicles are typically allowed on the airside to perform necessary upkeep on airport infrastructure, ensuring that everything functions correctly and safely.
