The ‘kei’ cars and trucks are growing in popularity in the U.S. But many states have explicitly banned them in recent years. A bill at the statehouse would allow them on Colorado roads.

Gov. Jared Polis recently signed a bill set to go into effect in 2027 to allow kei cars and trucks on Colorado roads — just not on interstates.

Texas has officially legalized the registration and operation of Kei trucks, small Japanese mini vehicles that have gained popularity for their efficiency and affordability.
