Trulli says Singapore still a worry for F1 drivers

Formula One drivers are still fretting about the sport's first night race less than a month before Singapore's new street circuit makes its debut.

"It's a new circuit, we don't know much about it, the schedule, the times of running. we all are a little bit concerned about the night race and the poor weather which might occur there," Toyota's Jarno Trulli told reporters at the Belgian Grand Prix on Thursday.

"It's a big question mark for everyone, we mustn't underestimate the situation."

Singapore will become the second new venue this season after last month's Valencia street race when the southeast Asian island state hosts the 15th round of the championship on Sept. 28 at the tail end of the monsoon season.

Unlike Valencia, which staged a couple of junior formula races on the street circuit a month before the grand prix to iron out any problems, Singapore remains untested.

"In Valencia they did a good job, so I am confident they can do a good job for Singapore," said Trulli. "But the location is different and the climate conditions are different.

"We are all a little bit uncertain because we probably don't have enough data. I haven't seen the circuit layout but that's not the problem. The problem is we don't know if the circuit is good enough, if the surface is good enough, if we have enough run-off areas, if the safety is good enough for a night race in wet conditions.

"There are several question marks and several concerns. I'm not saying that I don't want to race there, but that we might encounter some more problems than in Valencia."
