Grand Prix Drivers' Association director Mark Webber plans to consult MotoGP riders about the difficulty of racing under lights in the rain, ahead of this year's Singapore Grand Prix.
The floodlit MotoGP race in Qatar earlier this month was postponed until the Monday because of rain, and Webber believes the riders involved could offer some insight into the potential dangers should rain hit September's Singapore night race.
"I haven't spoken to any of the riders, but probably before Singapore I will," said Webber. "It looks like those guys could not run at all.
"I was surprised, but they are like us. They will race if they can, and if they can't they won't.
"The glare must have been very difficult and they are in a situation where they could go a day later, which was a nice luxury to have. I'm not sure we could do that in Singapore."
Although drivers had few complaints about visibility in last year's inaugural Singapore Grand Prix, there are still question marks over what would happen if it rains, as all the running in 2008 was in the dry.
Webber said that the GPDA is in regular contact with the FIA regarding the issue of visibility in night and twilight races.
"There are not many to come in the rest of the year," said the Australian. "Melbourne was more of a concern than Malaysia for us. It was a problem because of the rain and we are in constant contact with the FIA. I'm sure we will work out what to do."
