DRUGS AND ALCOHOL Use of drugs and alcohol impair a driver’s ability to safely use a vehicle. A driver with a BAC level of .05 is twice as likely to be involved in a crash, and the presence of alcohol increases the susceptibility to injury if involved in a crash. The presence of cannabis and the drug methyl- amphetamine increases the risk of being involved in fatal crashes. Drivers also need to be aware of the influence of any medications prior to driving. How to reduce risk: • adopting a zero drugs and alcohol policy for work related driving • avoiding or minimising the use of alcohol prior to driving • complying with road rules in relation to the prescribed level of alcohol • using transport alternatives at functions with alcohol (designated driver, taxis) • taking into account the influence of medications before driving FATIGUE Fatigue is mental or physical tiredness that affects a person’s ability to function. It may impair performance by reducing attentiveness, slowing reaction times, affecting judgement and reducing performance on skilled control tasks. It is estimated that fatigue is a factor in up to 25% of crashes. Being awake for 17 hours is estimated to cause a similar level of impairment to a .05 BAC level. Signs of driver fatigue, such as lane drifting, variations in speed, delayed reactions and reduced concentration, indicate there is already a risk. Individuals are unreliable judges of their level of fatigue. Consequently, the role of the employer in planning and scheduling work to minimise fatigue is paramount. How to reduce risk: • sharing the driving • using alternatives, such as public transport or taxis • planning longer trips to allow for regular breaks • encouraging drivers to take power naps if sleepy • minimising night driving (avoid driving at times when you’d normally be sleeping) • enabling staff to sleep overnight in motels where necessary • providing information on sleep, nutrition and drinks, such as water and coffee. 10 ISSUE 19 2019 / WWW.AFMA.ORG.AU
