Certainly there would be consequences, most remarkably the withdrawn of the approval for your driver license or permit. For that, you should have been convicted for any of the next: following too closely or tailgating,  or speeding or being in a speed contest.

Then sorry, but your license will be inevitably revoked.
That wouldn't be of any good, i guess. Well, ok, one more question, please. Where i can find info about installation fees, please?
