The “H” or “X” endorsements will expire no more than 5 years after the date the security assessment was completed. Having CDL endorsements allows a driver to have more career flexibility. While it might seem that an endorsement isn't needed now, it may be needed later for a different truck driving job.
How long does a endorsement last?
Endorsements stay on your driving record for 4 or 11 years depending on the offence. This can start from either the date you're convicted or the date of your offence. The endorsement is 'valid' for the first: 3 years, for a 4-year endorsement.
How do I get endorsements off my driving licence?
To remove expired endorsements from your driving licence, you'll need to apply to upgrade your licence for a replacement. You can apply by post, or via one of the seven MOT test centres that provide a checking service.
