Jarno Trulli has revealed that Formula 1's drivers are 'concerned' about the sport's inaugural night race to be held in Singapore at the end of next month - suggesting that the event may be 'not exactly what you really want from a safety point-of-view'.

The race will be held under floodlights around a concrete-lined street circuit in the city-state - but without the opportunity for any pre-weekend testing under the artificial lighting. What's more, there is a high chance of heavy rain, and the official timetable still has yet to be confirmed, with fears there will be precious little evening practice time allocated.

"At the moment we still don't know what the schedule of the weekend will be," Grand Prix Drivers' Association (GPDA) stalwart Trulli stated. "We are a little bit concerned - we go there, we haven't tested, we don't have any idea.

"It's going to be a night race, it's going to be the rainy season, so it's not exactly what you really want from a safety point-of-view. It doesn't look comfortable so far."

The GPDA - F1's driver safety union - is seemingly worried that the combination of the track's concrete walls, the lack of visibility and the potential for a wet grand prix could prove to be a dangerous cocktail, and Toyota star Trulli stressed that little could be drawn from MotoGP's first-ever night race experience in Qatar earlier this year.

"Riding a bike is different to driving a car," the experienced Italian underlined, "and they were racing on a circuit and we are racing on a street circuit. They had run-off and we have walls."
