Ignorance is not a valid defence and will not stand up as a reasonable defence in Court however this can sometimes amount to a special reason's plea if you can prove you genuinely thought you were driving with insurance. If you were driving a company vehicle and were under the impression you were insured, this may amount to a valid defence and your employer could face charges for letting you drive a vehicle uninsured. You would need to proof that; you didn't own the vehicle; you were using the vehicle as an employee; demonstrate how the vehicle was in your possession and that you had no reason to suspect you would not be insured. If your insurance company cancelled or failed to renew your insurance policy after receiving instructions to do so this could also be a valid special reason.
