The speedometer on my 2013 Toyota Prius 1.8 shows the speed about 5 km/h faster than the actual one (shown on the roadside meters and my GPS). Is this within the right legal range please? Thank you.

Hi there,
Yes this is common and most vehicles would read 103-105kmh when actually travelling 100kmh. It is a built in tolerance from the manufacture. There is a global standard for speedo accuracy and no speedo shall under-read. However, the standard allows for over-reading by up to 14% at some speeds.
