A937/A4128

Joe Crowley has been travelling up and down the UK looking at some of the nation's most dangerous roads and asking if there is more that can be done to make these routes safer for those who use them.

Joe is in Scotland to look at the A937 and, in particular, where it meets the A90 - a junction that has claimed a number of lives in the last decade. He meets the father of a young man killed at the junction and local campaigners, and hears the assessment of an independent road safety expert, before putting all the concerns to Transport Scotland.

Also on the show, he visits Buckinghamshire and the A4128, a road that was recently ranked as the most improved road for safety in the whole of the UK; and finally Joe visits the Transport Research Laboratory to find out what difference roadside advertisements make to drivers' concentration.
