Tier 4 to Tier 2 + Driving

[bizit524]

Greetings
I had a basic inquiring. I am from the US and I came this previous year on a Tier 4 student visa. I have since finished and have a job. He is wanting to sponsor me to a Tier 2 visa which is fine however he wants me to start to drive. We do a lot of on site work for small businesses.
From what I read on the UK gov website I can drive for 1 year on my US license while I get the UK license. However Since I have already been a Tier 4 student does that count as my 1 year ? as I have never owned a car or drove? Or does the 1 year start on my Tier 2 visa when it starts.

Edit: to add to this, we rely heavily on driving, currently the person that is driving will be leaving about the time my visa is expiring (tier 4) So I would have to start driving then. However before my boss does the paperwork and spends money to sponsor me I dont want to accidentally talk to him saying i can drive when in actuality i can't.

Any suggestions or information would be great

Your 12 months started the day you landed in the UK.

Did you go to a uni for your tier4 course?
And what is the job role that is being offered?

[bizit524]

Yes on my tier 4 I went to University of Edinburgh
My job role is a small business security consultant /repair technician

Thank you for the clarification.

The job role will not meet NQF6 requirement based on what you state. Alarm sales, installation and repair is the less glamorous title and is not role that can be filled using tier 2
