The reason for the 90 kmh limit is for vehicles operating under EU regulations. This was done for reasons of fair competition, so that all countries competing against each other follow the same rules. Therefore a vehicle operating under EU regs should be limited to 90kmh. If the vehicle is private or used under domestic regs then the UK speed limit of 60mph applies and the limiter may be disabled.
Exceeding the 90kmh limit as not speeding but is an infringement under EU regs. It is extremely unlikely anyone would get prosecuted for this unless an operator was brought in front of the TC with many other infringements and was shown to be willfully ignoring it. It may then be used in a case against them.
Time for a new rule then.
If the vehicle is on an international O licence the 90kph limit applies if not then a higher limit of 97kph limit will apply. It shall be an offence to use a vehicle calibrated to 97kph to be used on international journeys.
Over to you Grant…
