A pilot project to display travel times on electronic motorway signs has been launched by the Highways Agency.
The estimated times are based on current driving conditions
The aim of the scheme on the M6 and M5 in the Midlands is to inform motorists of delays, and also to cut congestion.
The signs will display estimated times it will take drivers to get to a range of destinations.
The project is being piloted on the M6 from junction 15 at Stoke-on-Trent down to the M1 near Rugby, and on the M5 between Birmingham and Bristol.
These two roads were picked for the pilot as they are among the country's most heavily used and carry about 200,000 vehicles every day.
The scheme uses the existing electronic signs, which display information about accidents and delays, in parts of Staffordshire, Leicestershire, Warwickshire, Worcestershire, Gloucestershire and the West Midlands.
Steve Crosthwaite, from the National Traffic Control Centre, in Quinton, West Midlands, said the scheme was running until September with a view to expanding it nationwide if successful.
He said: "We want to inform motorists in an easy way on the state of the roads so that they can make informed choices about their journey."
