West Yorkshire roads still icy despite gritting
Drivers in West Yorkshire have been warned that roads could remain dangerously icy, despite being gritted, because of extremely low temperatures.
Temperatures in parts of the region dropped below -9C early on Friday.
Russell Martin, highways maintenance manager at Leeds City Council, said this made road salt less effective.
"At minus eight you need more, more and more salt," he said. "At minus 10 you just keep putting it on but it will be really slow to work."
At -15C salt becomes ineffective.
Mr Martin, who is in charge of 30 gritting teams working across Leeds, said: "The message we want to get over to people is we must take extra care when we get these extreme temperatures.
"We're not used to it."
Richard Lewis, Leeds City Council's executive member for development, said: "While clearly we can't just make the snow go away and there are limits to how much we can clear, our gritting teams work all hours in extreme conditions and are extremely dedicated to their jobs.
"We also ask people to do their bit where they can to keep areas outside their own homes clear and to look out for neighbours who may need help."
