Microsleep, a brief lapse into sleep while driving, contributes to 20% of road accidents in Malaysia, with festive travel increasing risks.

KUALA LUMPUR: Brief episodes of microsleep are a major factor in Malaysian road accidents, accounting for roughly 20% of cases annually.

Malaysian Institute of Road Safety Research deputy director-general Prof Dr Siti Zaharah Ishak said the phenomenon is caused by fatigue and the body’s internal clock.

“Microsleep happens when we drive without being aware for a short period,” she said during a Bernama TV programme.

She explained drivers can have their eyes open yet be unconscious for two to 10 seconds.

Risks escalate during festive seasons and school holidays with long-distance travel.

The Malaysian Highway Authority projects over two million vehicle movements on highways during these periods.

Early warning signs include fidgeting in the seat and inconsistent speed.

Siti Zaharah advised drivers to get sufficient rest and plan journeys carefully.

“On average, people need seven hours of sleep to feel fully refreshed,” she noted.

She stressed that sleep quality is more important than just duration.

Drivers feeling drowsy should stop and rest at highway rest areas.

Other tips include opening windows for fresh air to maintain alertness.

If stuck in traffic, flashing headlights or honking can help a driver stay awake.

This can also warn other motorists who might be feeling sleepy.

MIROS also evaluates vehicle safety technologies to improve road safety.

These include advanced driver-assistance systems like lane departure warnings.

Automatic emergency braking is another feature being assessed to encourage better habits.
