I have not received the tax disc. Can I use the vehicle without the tax disc displayed?
When you apply for a tax disc online or by using our phone service you are able to legally continue to drive your vehicle for up to 5 days after the tax disc has expired while you wait for the new tax disc to arrive. This will only apply when you have applied for a new tax disc before the current one expires. You should continue to display the expired disc on your vehicle, until the new one arrives.
