Currently they've granted that licences can be lapsed/inactive for a further year,you should have received an email from them detailing when your licence needs to be reactivated...or gone forever,
The current draft proposal is to allow vehicles that have already reached their maximum age limit(covered by previous drafts) and vehicles that will reach their maximum age during 2022 to continue operating for 1 more year.
What's wrong with your jammer btw?
