Easter disruption creates hidden fatigue risks for fleet operators

Routine changes, increased traffic and seasonal shifts could impact driver alertness – even before a shift begins.
Easter may bring quieter roads for some operators, but fatigue experts are warning it can also introduce less visible and often underestimated risks for fleet safety.
According to AutoSense sleep and fatigue consultant Katrina Aubrey, disrupted routines can significantly impact driver alertness, particularly for those returning to work or operating outside normal schedules.
“Fatigue is not just about hours worked; it’s driven by sleep, circadian rhythm and routine,” Aubrey says.
“Over Easter, people often shift their sleep patterns, going to bed later, waking earlier to travel, and changing daily habits. That creates what we call ‘social jetlag’, where the body clock is out of sync.”
For fleet operators, this means drivers may present for work legally compliant, but physiologically impaired.
“A driver can come back from a long weekend feeling fine, but if their sleep has been disrupted, their alertness and decision-making may already be compromised before they even start their shift,” Aubrey says.
The risk is compounded by changing road conditions over the Easter period. While heavy vehicle volumes may reduce, operators still on the road face increased interaction with light vehicles, higher congestion and more unpredictable driving behaviour.
At the same time, the end of daylight saving in some states can further disrupt sleep timing and daily rhythms, adding another layer of fatigue risk as drivers adjust to changing light conditions.
Australian data from Guardian by Seeing Machines, distributed by AutoSense, shows fatigue events continue to peak in the early morning, particularly between 3am and 5am[1], with weekends consistently recording higher levels.
These patterns are reflected in national crash data[2], which shows a significant proportion of fatal incidents occur late at night and on weekends.
Aubrey says Easter is a timely reminder for operators to review how fatigue risk is managed across their business, particularly during periods of routine disruption.
Practical steps include:
Ensuring drivers have adequate sleep opportunity before shifts
Reviewing rostering around early starts and post-holiday returns
Identifying high-risk windows such as early morning operations
Reinforcing driver education around fatigue awareness and self-reporting
As enforcement increases over the Easter period, including double demerits in many states, Aubrey says a compliance-led approach alone is not enough.
“A logbook manages hours – it doesn’t manage sleep. Fatigue doesn’t always feel obvious, which is what makes it so dangerous. It needs to be treated as a biological risk, not just a scheduling issue. The more proactive we are, the safer outcomes we’ll see for both drivers and operators.”
2.BITRE's report on run-off-road (RoR) fatal crashes note they are more common late at night (with the difference between fatal RoR and fatal non-RoR crashes particularly notable between 11.00pm and 2.00am) and on weekends, and more than 50% happen in areas with a posted speed limit of at least 100 km/h (BITRE)
