Drink driving is defined as driving or attempting to drive a motor vehicle on the public highway or a public place whilst under the influence of alcohol exceeding the prescribed limit.
If you are convicted of drink driving it is obligatory that you are disqualified from driving unless the Court finds that a "special reason" exists for not doing so (see below).
The Court does have the opportunity to consider sending a convicted motorist on a rehabilitation course. This entitles a reduction of 25% of the disqualification period. A mandatory 12 month ban would therefore be reduced to 9 months.
