Do I have to have my dash changed?
Hi. I have a question regarding mph and km/h on a used car imported from UK. Is it the law here to be able to see km/h on the dash?
Our answer:
Hi Karen,
There is no legal requirement to have a speedometer that reads in km/h rather than mph, and it’s not a failure point on the NCT. Usually, UK cars will have a speedo that reads in both mph and km/h, but it’s easy enough to learn which are the equivalent speeds.
