How are vehicle corridors marked on the airside surface?

• A. Blue dashed lines.
• B. Parallel solid white lines spaced 7.5 meters apart divided down the middle by a dashed line.
• C. Two solid red lines with a white gap.
• D. A single white line.

Answer: (B)

Vehicle corridors are marked to provide a clearly defined, safe path for ground vehicles that keeps traffic out of aircraft movement areas. The standard marking uses two parallel solid white lines forming the outer edges of the corridor, spaced 7.5 metres apart to indicate the corridor width, with a dashed line down the middle to show the centerline. This setup gives drivers a precise boundary to stay within and a reference line to align to, supporting steady, controlled movement on the airside surface. Other markings don’t establish this clear boundary and width for vehicle paths: blue dashed lines aren’t used for corridors, two solid red lines with a white gap signal a restricted or prohibited area, and a single white line doesn’t define a full corridor or its width.
