Teams may use only one registered vehicle, unless they have faster than a 20-minute or less 5K team average; these teams qualify for two registered vehicles. Cell Phones and Radios are recommended for 2-vehicle teams. Team vehicles must be large enough to provide all passengers with access to a safety belt. Large vans, minivans and SUV's are allowed. Buses of any kind (mini, shuttle, or any other type of bus), RVs, trailers or limos are NOT allowed. Team's violating this rule will be immediately disqualified.
