Motorists are being urged to dispose of their litter responsibly in a bid to keep England's motorways and A roads clean.
The Highways Agency said around 250,000 sacks of litter are cleared from motorways each year, but figures in North West England and the East Midlands fell after the agency ran a litter awareness campaign last year.
Roads minister Mike Penning said: "Litter is an unsightly and unnecessary burden and one that we can easily avoid - that's why I am asking people to take one simple step towards making the roads a safer and more pleasant environment for everyone.
"The money and staff resources spent removing nearly a quarter of a million sacks of litter from England's motorways could be far better spent elsewhere."
He added: "Following the Bag it, Bin it message is an easy way to reduce litter. If all drivers kept a bag in their vehicle to store rubbish and then disposed of it safely, it would be a really positive move in tackling roadside litter."
