Cambridgeshire police say a woman who drove the wrong way along the A11 through Cambridgeshire and Suffolk is lucky she didn't crash.
She drove for around 15 miles before police managed to stop her safely.
"We believe the lady had travelled approximately 15 miles on the wrong side of the road. The incident happened at 1.30pm on Sunday afternoon. The road was very busy, there were a large amount of vehicles using the road and she was very lucky that she wasn't involved with a vehicle travelling the correct way.
