3.7.6 Exemptions to drink/drug driving reductions


Severe injury or death

If the drink or drug driving relating to the work-related transport accident results in the worker’s death or ‘severe injury’, the worker’s weekly payments must not be reduced.

See: Serious and wilful misconduct

BAC or drug concentration did not contribute to the injury

If the worker can satisfy the Agent on the balance of probabilities that the alcohol or drugs did not contribute to the injury, the worker’s weekly payments must not be reduced.

The Agent is not required to assess whether the worker’s BAC or drug level contributed to the injury, it is only where the worker relies on the defence that his or her concentration of alcohol or drugs did not contribute to the injury.

For exampleClosed The injury occurred while the worker (a bus driver) was parking legally in a parking bay at the bus depot and is able to prove that the BAC did not contribute to the transport accident occurring when another driver ran into the bus.

Worker is a train or tram driver

If a worker is injured whilst driving a train or tram the exception does not apply. This is because the drink/drug driving offences originate from the Road Safety Act 1986 which excludes trains and trams from the definition of ‘motor vehicle’.

The Agent must consider whether the serious and wilful misconduct provisions are applicable instead of the reduction provisions.
