Is driving a right-hand drive JDM car on US roads legal?

Right-hand drive vehicles are legal in all US states for private road use. There is no federal prohibition on RHD cars. State-level restrictions vary — some states have specific requirements for mirrors or require the driver to be able to reach controls without difficulty. Practical challenges include passing other vehicles on two-lane roads, pulling up to drive-through windows, and reading certain road signs. Most RHD owners adapt quickly with minimal safety concerns.
