Are you a sleep derived zombie at the wheel?

See a friend reach for the car keys after a boozy night out and many of us will speak out or persuade them to hand over the keys. But how if they insist on driving tired?

Fatigue is a major factor in up to 1 in 5 road crashes and according to experts, remaining awake for periods in excess of 18 hours can impair abilities to a degree that is comparable to exceeding the drink drive limit in many countries.

Ford Europe commissioned the creation of a “Sleep Suit” that enables wearers to experience the debilitating effect that tiredness can have. Transport accidents are the leading cause of death among young people, and we will integrate training with the suit into Driving Skills for Life (DSFL) our free young driver training programme for 17- to 24-year-olds.

Dr Gundolf Meyer-Hentschel, CEO, Meyer-Hentschel Institute, who developed the “Sleep Suit”.

“Drive when you’re tired and you risk driving like a zombie – becoming a danger to yourself, your passengers and everyone on the road around you. Young adults very often subject themselves to ‘intentional sleep deprivation’ – forcing themselves to stay awake so that they can juggle the demands of busy social lives, long working hours and studying for exams.”

The suit partly consists of special goggles that simulate extreme exhaustion, including microsleeps – an uncontrollable response to tiredness. Microsleeps can result in those behind the wheel driving blind for 10 seconds or more, sometime with their eyes still open, during which time they may have covered hundreds of metres. There may be no recollection afterwards that this has happened.

Connected to a smartphone app, the goggles can be set to simulate the brain shutting down and the driver effectively seeing nothing ahead of them for half a second, then for increasingly longer periods, up to 10 seconds. Worn together with a specially designed cap, vest, arm and ankle bands – with a combined weight of more than 18 kilogrammes – the overall effect offers an insight into the degree to which tired drivers are impaired. In the US, most drowsy driving crashes are caused by under-25s.

DSFL Manager, Jim Graham.

“We were determined to raise awareness of drowsy driving and the ‘Sleep Suit” is the perfect way to demonstrate this. Many people have been thankful that a friend or family member has volunteered to be the designated driver on a night out. But just because they haven’t been drinking doesn’t mean that they are safe to drive if, for example, they are exhausted after staying up all night.”
