How many cones are used during the serpentine driving skill?

Answer: C — Three

Serpentine driving tests your ability to steer smoothly around obstacles while staying in your lane and keeping a steady speed. The drill uses three cones arranged to create a short zigzag course, so you must alternate direction around each cone. That setup provides enough direction changes to demonstrate precise steering and throttle control without making the drill overly long. Using fewer than three wouldn’t challenge your handling enough, while four would extend the course beyond what's typically required. So three cones is the standard setup for this skill.
