The Road Safety Act 1986 Section 52 mandates that the driver of a large vehicle must maintain zero blood or breath alcohol level while driving the large vehicle. This provision of law places such driver in the ranks of learners, probationary license holders, taxicab drivers and commercial driving instructors.
Authorities are especially concerned in the case of drivers of heavy vehicles because of the potential damage that it can cause if involved in an accident or collision. The threat to life and property is higher when a heavy vehicle is involved in an impact. Hence, the emphasis on zero levels of alcohol regardless that the driver of the large vehicle may be an experienced driver. Drivers of heavy vehicles are issued infringement notices.
Charges are filed with the court to which the driver should apply for remedy. The court may impose fines, demerit points, penalties of imprisonment and cancellation of licenses. Drink driving offences are considered "Major Offences" under the law and thus attract heavy fines, periods of licence disqualification and possibly terms of imprisonment.
If you have been charged with a traffic offence or are under Police investigation, it is important that you seek legal advice.
