Getting a vehicle on the road can be a little confusing, especially if it has none of the legal requirements already. These requirements are insurance tax and MOT, all of which are necessary for a vehicle to be used on public highways.
Getting these requirements are usually only an issue with second-hand vehicles. Brand new vehicles often do not require a MOT for a number of years, and insurance and road tax are much easier to acquire, and sometimes even included.
In order to get road tax, a vehicle must have a MOT. In order to get a MOT, a vehicle must be insured. So the order that they need to be obtained in is Insurance, then MOT, then road tax.
Once a vehicle is insured and taxed it is still not road worthy unless it has a MOT. Fortunately, it is legal to drive a vehicle to the MOT testing centre to get one, so long as it is a direct route to the testing centre.
