Rules by state
Colorado
Legality
As of May 3, 2025, legality on Kei trucks in Colorado seems to be mixed. Call your local DMV to clarify the registration of Kei cars. People have been successful in registering Kei cars in Colorado and it seems to be easier in mountain towns where no emissions test is required.
As of May 3, 2025, there is a bill heading to the governor's desk to codify Kei cars in Colorado. This bill will allow kei cars that are either 25 years old or older when imported into the country, or over 25 years old when it was previously issued a title in the U.S. Once it is signed by Polis, this proposed law will go into effect on July 1, 2027.
