In the quiet exhaustion that follows the arrival of a new life, a danger quietly takes shape on the road. A Monash University study of over a thousand Australian parents reveals that nine in ten drive while fatigued in their infant's first year — more commonly than speeding or drunk driving — averaging just six hours of broken sleep each night. The research asks us to recognise that the vulnerability of new parenthood does not end at the front door, but travels with parents onto roads shared by all.
Nine in 10 new parents drive fatigued, Monash study warns
New parents experiencing severe sleep deprivation face elevated risks of driving errors, concentration lapses, and potential traffic accidents affecting themselves and others.
Fatigued driving was more common than speeding or drunk driving
Mark
Why does this matter more than, say, a study about speeding or drunk driving?
Mimi
Because nine in ten parents are doing it. It is not a fringe behaviour. It is the norm. And because nobody is talking about it as a safety issue the way they talk about drink-driving.
Mark
But parents have always been tired. What is different now?
Mimi
Nothing is different. That is the point. We have known this for decades. The study is not revealing something new—it is quantifying something we have ignored. And it is showing that the risk is real and measurable.
Mark
Why don't parents just take naps instead of drinking coffee?
Mimi
Because they cannot. A nap takes time. A parent with a newborn does not have 20 minutes to spare. Coffee is instant. It is what you can do while holding a baby or between feeds.
Mark
So the solution is just to tell people to nap more?
Mimi
No. The solution is structural. It is flexible work, it is antenatal education, it is making sure people know their car has fatigue detection and how to use it. You cannot shame exhaustion away.
Mark
What happens if nothing changes?
Mimi
Parents keep driving tired. Some of them crash. Some of them hurt themselves or their child. Some of them hurt someone else. The risk is there every single day.
El Pulso
- Nine in ten Australian parents with infants under 12 months drove fatigued in the past month — making exhaustion the most common risky driving behaviour, surpassing speeding, phone use, and drink driving.
- Parents averaging just six hours of disrupted sleep nightly reported sharply higher rates of concentration lapses, driving errors, traffic violations, and aggressive behaviour behind the wheel.
- Despite the scale of the problem, most parents reach for coffee or loud music rather than rest — the only remedy that actually works — leaving the underlying danger unaddressed.
- Fewer than one in five parents had fatigue-detection technology in their vehicle, and many were unaware whether their car carried such systems at all.
- Researchers are urging healthcare providers, employers, and road safety organisations to treat new-parent fatigue as a serious public safety issue — embedding awareness into antenatal care and workplace flexibility policies.
In the quiet exhaustion that follows the arrival of a new life, a danger quietly takes shape on the road. A Monash University study of over a thousand Australian parents reveals that nine in ten drive while fatigued in their infant's first year — more commonly than speeding or drunk driving — averaging just six hours of broken sleep each night. The research asks us to recognise that the vulnerability of new parenthood does not end at the front door, but travels with parents onto roads shared by all.
A study from the Monash University Accident Research Centre, published in the Journal of Safety Research, surveyed 1,160 Australian parents and found that nine in ten with a baby under 12 months had driven while exhausted in the past month. Parents averaged just six hours of sleep nightly, almost entirely disrupted by infant care — and the resulting fatigue on the road proved more prevalent than speeding, illegal phone use, or driving under the influence.
The consequences were not abstract. More than 80 per cent of fatigued parents reported poor concentration, tired eyes, and a heightened tendency toward driving errors and traffic violations. These are the conditions that precede crashes, not merely discomfort.
Yet most parents responded with ineffective fixes — coffee, music, open windows — rather than the one thing that genuinely helps: rest. Fewer than one in five had fatigue-detection technology in their vehicles, and many did not know whether their car was equipped with such systems.
Lead researcher Associate Professor Sjaan Koppel identified a clear gap in how society prepares new parents for this risk. The study's authors are calling for fatigue education to be integrated into antenatal and postnatal care, for road safety bodies to better communicate how detection systems work, and for employers to offer flexibility that reduces pressure on sleep-deprived parents to drive when they shouldn't. The first year of parenthood, the researchers argue, is a period of acute vulnerability — one that extends well beyond the home and onto roads shared by everyone.
A Monash University study has found something that will ring true for anyone who has sat behind the wheel at 3 a.m. with a newborn at home: nine in ten Australian parents with a baby under 12 months old have driven while exhausted in the past month. The research, conducted by the Monash University Accident Research Centre and published in the Journal of Safety Research, surveyed 1,160 parents to understand how broken sleep patterns shaped their behaviour on the road.
The numbers are stark. Parents in the study averaged just six hours of sleep each night, nearly all of them reporting disruptions tied directly to caring for an infant. What makes this finding particularly striking is not just how widespread the problem is, but how it compares to other risky driving behaviours. Fatigued driving was reported more frequently than speeding, illegal mobile phone use behind the wheel, or driving under the influence of alcohol or drugs. In other words, the thing most likely to put a new parent in danger on the road is not recklessness or substance use—it is exhaustion.
The consequences are measurable. Parents who drove while fatigued reported significantly higher rates of concentration lapses, driving errors, traffic violations and aggressive driving. More than 80 per cent of participants experienced the physical symptoms of fatigue: poor concentration, tired eyes, increased blinking, and a heightened likelihood of making mistakes at the wheel. These are not minor inconveniences. They are the precursors to crashes.
Yet the response from most parents was predictable and ineffective. When faced with fatigue, they reached for coffee, turned up the music, or rolled down the windows. These are short-term band-aids. What actually works—taking a nap, genuinely resting—was used far less often. Fewer than one in five parents reported having fatigue-detection technology in their vehicle, and many did not know whether their car had such systems or how they worked.
Associate Professor Sjaan Koppel, lead author of the study and associate director of the Monash University Accident Research Centre's Behavioural Science team, pointed to a gap in how new parents are prepared for this reality. Healthcare professionals, employers and road safety organisations, he said, all have a responsibility to help parents understand that their own sleep deprivation is a genuine threat to safety on the road, and to offer practical ways to manage it.
The researchers are calling for fatigue education to be woven into antenatal and postnatal care. They want road safety organisations to raise awareness about fatigue-detection systems and how they work. They want employers to offer flexible arrangements that reduce the pressure on exhausted parents to drive when they should not. None of this is complicated. It is simply recognition that the first year of parenthood is a period of acute vulnerability—not just for the parent and child at home, but for everyone sharing the road with them.
