It is not an alcohol blood test. It is an indicator. No ones
CDT test is 0% but below 1% shows abstinence from alcohol.
I filled the DR1 form in honestly and ticked yes to question 4 - Within the last 6 years have you been dependant on or regularly misused alcohol.
Also yes to question 6 - Within the last 6 years have you had a problem with your family/work or home life due to your alcohol intake?
All the others I ticked no and my last drink date was 25/03/2019 (nearly 16 months ago). My alcohol problems are all in the past and giving up the drink has been so rewarding in my personal and professional life so I didn't want to lie on the form.
My GP knows my history and I meet all the requirements set out by the DVLA to have it reinstated but they obviously just want to make sure they cover all bases.
