Drivers warned ahead of wet NSW weather

Drivers are being urged by police to be careful on the roads, with rain falling in NSW and forecast for the next seven days.

Drivers, motorcycles riders, cyclists and pedestrians alike need to be aware of the conditions, which will make roads slippery and unpredictable, Acting Assistance Commissioner David Driver says.

"Personal responsibility over the next seven days will be the key to saving lives," he said in a statement on Wednesday.

Road users are asked to drive or ride with lights on in heavy rain, to double the `three second gap' rule in rain, avoid flooded roads, and be aware that roads may become unstable.

"Those that continue to speed, drink or drug drive, not wear a seatbelt or proper helmet, are fatigued or distracted by a mobile phone are the ones that will be a greatest risk during this current wet weather period," Mr Driver said.
