Wadsworth v Gillespie
A car stopped at the white lines of a T-Junction.
The driver saw an approaching motorcyclist from his left signalling left. The driver relied on that signal and pulled out onto the main road and a collision occurred.
Motorcyclist: 1/3rd at fault for displaying a misleading signal
Driver: 2/3rds at fault for assuming the motorcyclist was about to pull in.
Note that in 2003 a similar case involving a car driver and a lorry driver was heard with a different outcome. See here
