In formation driving, communication among vehicles is most commonly conducted using radio communications. This method allows for quick and clear exchanges of information between drivers, which is essential for maintaining coordination and safety while traveling in a group. Radios enable the crew to share important updates, such as changes in speed, direction, or any unforeseen hazards on the road, without the distraction of having to use hand signals or visual cues, which can be less effective and more prone to misinterpretation, especially at speed.

While other methods like hand signals or visual cues can play a role in smaller, less coordinated situations, they are not as practical or reliable in the context of formation driving where consistency and clarity are vital. Communication via cellphones can introduce delays and distractions, making it less suitable for this type of driving. Therefore, radio communications are the best choice for effective and efficient communication during formation driving scenarios.
