Drivers on the expressway have been urged to maintain a gap between vehicles and to adhere to the speed limit when travelling on the Southern Expressway.
The Police Spokesman Ajith Rohana said on a normal day, drivers are required to maintain a 100km speed, but in the event of rain to immediately reduce the speed.
He further urged drivers to refrain from speaking on the mobile phone while driving on the expressway.
DIG Ajith Rohana said these factors could lead to accidents, resulting in deaths or injuries.
He pointed out that the multi-vehicle collision that was reported on the Southern expressway yesterday was due to the driver not concentrating on the road and also not maintaining a gap between the vehicle in front.
DIG Ajith Rohana also advised motorists to call the expressway emergency hotline in the event of an emergency or a weather-related issue.
He said drivers will be permitted to stop the vehicle on the side of the road with their hazards switched on to make the phone call. However, he stated that it is an offence to stop the vehicle on the side of the road for any other reasons.
