s49(1)(ba) Driving Whilst Impaired by a Drug

Have you been charged with Driving While Impaired by a Drug? 

There are a number of issues to consider if you have been charged with this offence.

• Can the prosecution make out their case?
• Were you impaired?
• Have police video recorded the impairment assessment?
• Do you have any relevant prior matters?

It is an offence against the Road Safety Act 1986 (RSA) section 49(1)(ba) to drive a motor vehicle or be in charge of a motor vehicle while impaired by any drug.

If you are reasonably suspected by a police officer to be driving or in control of a motor vehicle while impaired by a drug (i.e. a police officer thinks you are unable to drive properly because you are impaired by a drug: s 48(1AD)), you may be required to undergo a drug assessment and could be charged.

The list of drugs applicable to s 49(1)(ba) is extensive, and is not limited to illicit drugs. It may include prescription or non-prescription medication which could impair your driving or ability to control a motor vehicle. This is an important distinction.

If on an analysis no drug, other than a permissible non‑prescription drug or a prescription drug, was found present in the person’s body, the alleged offender may have a defence because they did not know and could not reasonably have known that the permissible non-prescription drug or the prescription drug, or the combination of drugs, could impair driving if consumed or used in accordance with advice given to them by a registered medical practitioner.

Preparation is important to the success of any matter. If you have been charged with a driving or being control of a motor vehicle while impaired by a drug and your driver’s licence is important to you, don’t go to court unrepresented.

For the purposes of disqualification, section 50AA of the RSA deems driving offences for which you were convicted over 10 years ago not to be a prior offence. However, it is still at a Magistrates’ discretion to disqualify you from driving for longer than the mandatory 2 year minimum even were there is more than 10 years between offences.

If you have been charged with driving while impaired by a drug, the police may also immediately suspend your licence pursuant to s 85A. This would mean you cannot drive until your matter has been determined at court, but this suspension can be appealed while awaiting the court hearing for the alleged offence.
