The penalties for any of the offence   described above are very severe and are set out in the following table. If a person commits an offence and has committed any of the offences listed in the table within the previous five years, the person is dealt with as a second   offender  , whether or not both offences are in the same category. Where the previous offence is a first offence of exceeding the prescribed concentration of alcohol of .05-.08, the period is 3 years. As of 1st December 2005, in determining previous offences both convictions   and   expiated offences will be counted, however only expiated offences committed after the 1st December 2005 can be taken into account.

Automatic loss of licence applies for the majority of drink driving offences from the 1st December 2005. For further details see IMMEDIATE LOSS OF LICENCE. For offences committed prior to this date the suspension/disqualification occurs on conviction.

People who have committed an offence more than five years earlier (3 years for a .05 -.08 first offence) are given a penalty within a first offence category, but can expect the court to take the previous offence into account and give thedriver a higher penalty within that range.
