Magistrates imposed a 12-week jail sentenced suspended for a year.
Magistrates outlined their reasons for his suspended jail term.
They said: 'This offence was committed only a short time after the disqualification was imposed when the defendant was under the influence of alcohol.
‘He drove a long distance of about 70 miles.
‘He was also driving a commercial vehicle in the course of his employment. The imprisonment is suspended because the defendant has sought to address his alcohol problem on a voluntary basis.’
Fuller, of Cope Court, Maidenhead in Berkshire, was banned again for 40 months.
He must completed a nine-month alcohol treatment programme and 15 days' rehabilitation activities.
Fuller must pay a £122 victim surcharge and £85 prosecution costs.
