What is the maximum speed allowed on Taxiway Alpha?

• A. Up to 30 knots
• B. 60 knots
• C. 15 knots
• D. 40 knots

Answer: (A)

On taxiways, a published speed limit is set to keep taxiing safe and manageable around other aircraft and vehicles, especially at intersections and when ATC needs to manage traffic flow. For Taxiway Alpha, the allowable taxi speed is up to 30 knots. This limit provides a good balance between keeping things moving efficiently and allowing enough control to stop quickly if another aircraft or vehicle appears in the path or conditions change.

In practice, you stay at or below that published limit unless ATC directs otherwise, and you slow further in wet or slippery surface conditions, when following a preceding aircraft, or in high‑traffic or complex taxiing situations. Speeds like 60 knots or 40 knots exceed the typical taxiway limit and aren’t allowed unless specifically cleared; 15 knots is below the maximum but not the value that defines the limit itself.
