Vehicles with steering wheels positioned on the right-hand side, common in countries like the United Kingdom and Japan, are permitted on American roadways. This legality is rooted in the absence of federal legislation prohibiting their import or use. For instance, a privately imported vehicle manufactured for a right-hand traffic market can be registered and driven in the United States. This applies to classic cars, newer models, and even postal service vehicles designed for right-hand delivery.
The ability to operate these vehicles provides several advantages. Collectors can enjoy historically significant automobiles. Individuals relocating from right-hand traffic countries may find driving a familiar vehicle setup more comfortable and safer during their transition. Additionally, specialized vehicles like certain mail delivery trucks retain their functional purpose. This allowance reflects a balance between upholding road safety standards while acknowledging the practical needs of specific vehicle uses and individual circumstances. Historically, this policy has persisted, even as the automotive landscape has evolved, demonstrating a consistent approach to vehicle regulations.
