i have found from experience that as long as your nice if your pulled over and can prove you purchased the vehicle that day they normally give you a days grace. It does depend if you have a current MOT and Insurance document on you at the time.
There is something else you can do if you find it a problem. Before you buy a vehicle you can and always, have been able to, check for vehicle tax prior to purchase either on line or via phone and so can make appropriate arrangement to pick up any cars you wish to buy.
For thous that are concerned about taxing on line i am sure they will still have the facility to go to your local post office to get your tax.
