Traffic Radio is a new Highways Agency initiative available on digital radio and the internet.
However, not many cars have digital radios, so listening to information on the move could prove difficult.
Nigel Wonnacott of the Society of Motor Manufacturers and Traders (SMMT) said: “One of the issues is the coverage, which is not as comprehensive as it could be. Some manufacturers were concerned that if the radio was fading in and out as you were driving, most drivers would find it unacceptable.”
Transport minister Tom Harris, who launched the scheme following a year-long trial, said: “Traffic Radio will provide helpful information to enable people to make choices about their journey.
“Those with DAB radios in their cars will also be able to make informed decisions about alternative routes, should conditions change when they are en route. And people with mobile internet access will be able to check the latest conditions when they take a break from their journeys.”
