Millions of motorists could face heightened risks this weekend when the clocks spring forward. On the final Sunday of March, timepieces will adjust, potentially disrupting the body's natural circadian rhythm.
A nationwide survey of 2,000 UK motorists conducted by car insurance firm Dayinsure discovered that seven in 10 acknowledge driving while tired, with nearly half reporting increased fatigue when the clocks advance, as mornings remain darker.
Operating a vehicle while fatigued can result in slower reaction times, impaired judgement and diminished concentration.
Road safety specialists warn that tired drivers can pose dangers comparable to drink-driving in terms of their effect on driver performance.
One 2022 investigation from Surrey University demonstrated that following the clock change, drivers' behaviours become riskier, while their reaction time and situational awareness become compromised.
Researchers from the University of Surrey and the University of Padova in Italy examined 23 men, assessing their driving before and after daylight savings, reports the Express.
The men navigated an 11.5km route on a driving simulator featuring a lengthy straight road with an unbroken centre line, travelling behind another vehicle.
Before the clocks changed, just 9% attempted to overtake.
Afterwards, 39% did so.
Chris Bibby, CEO of Dayinsure, explained: "Many drivers underestimate just how dangerous fatigue behind the wheel can be.
"Losing even a small amount of sleep or driving when your body clock is out of sync can significantly affect concentration, reaction times and decision making."

"The clocks changing may seem like a minor adjustment, but for drivers who are already starting work early or commuting in darker mornings, the effects can quickly add up."
For those who commute during the early morning hours, it's advisable to exercise additional caution when the clocks shift.
Chris added: "If you're feeling overly tired, it's always safer to delay your journey where possible, take breaks on longer drives and make sure you're fully alert before getting behind the wheel."
