What do “safety zones” refer to in the context of airfield driving?

In the context of airfield driving, "safety zones" specifically refer to the areas around aircraft where vehicle access is restricted. This is crucial for preventing accidents, as the proximity of vehicles to aircraft can lead to dangerous situations both for the crew operating the aircraft and for those driving vehicles in the vicinity. Safety zones are implemented to ensure that there is a controlled environment around aircraft, limiting the potential for collisions and ensuring that all personnel remain protected.

These zones are clearly marked and regulations are typically reinforced through signage and training to ensure that drivers understand the importance of respecting these boundaries. This approach enhances overall safety at the airfield, ensuring both the security of operations and the safety of personnel involved. The other options do not adequately capture the significance or purpose of safety zones within an airfield's operational framework.
