Here’s a hilarious catch: if you SORNed the car and canceled the insurance, you probably saved about thirty bucks a month. Now, to unsorn it, you have to pay backdated tax from the day you first drove it. Except you haven’t driven it yet! The logic here is pure wizardry.
If you get caught driving a SORNed car without going through this process, the fine is huge. Like, “could have bought a used motorcycle” huge. Or you can have your car clamped, impounded, or crushed into a metal cube the size of a microwave. The police really, really don't like SORN cheats.
On the bright side, if you’ve done everything right, you can drive away legally. Just remember: the moment you park it again without taxing it, you’ve sorned it once more. It’s a cycle.
