"You can add one more state to the places where you can't register the three-wheeled Polaris Slingshot for the road. Connecticut had already decided that the trike didn't fit its definition of a motorcycle, but the company tried again anyway by taking one directly to the DMV headquarters there. The government officials took a look and came away with the same ruling on the vehicle – it's just not a cycle by their criteria."
"According to a Polaris press release posted on Slingshot Forums, the company is still working with Connecticut, Hawaii, Indiana and Maryland to get the trikes classified in the US. However, this announcement says that the earlier problem in Texas is now largely resolved with just the matter of how to title it. Previously, the Lone Star State said a motorcycle must have a saddle-type seat arrangement, not chairs like the Slingshot."
