Hi nuttynarna 

you need to look at this in two ways, first is the conviction spent or unspent 

if your licence was not endorsed by the court then the offence will become spent 13 months from the date of conviction. If your licence was endorsed then the conviction becomes spent 5 years after date of conviction.

if it is unspent you will have to disclose it to insurance etc if you are asked to you have any unspent convictions, if you are not asked you don’t have to disclose.

in regards to filtering and the enhanced or standard DBS then this offence will show for 11 years on an enhanced and standard DBS, during this time if undertaking this level of check then you will have to disclose. Once 11 years has passed then the offence will filter and no longer have to be disclosed.

based on the offence yes you will have to tell your employer especially if you have a new DBS check coming up, but it should be seen for what it is a driving conviction nothing else. There are many people out there that have this type of conviction and work in healthcare and have no issues what so ever

hope this helps
