Beware of Cars From Your Left Stopping
Make sure that you look for cars approaching from the left as they to may need to give way to cars entering the junction from their left.
So you may expect the car to drive past you, so that you can go behind it, however, rather than drive past you it may just abruptly stop in front of you.
Be aware that they may stop in front of you
However even if you can see that there is no traffic coming down from the
cars left hand side, don't presume that he will clear your car and keep going.
They may never have encountered a Y junction before
and very often drivers just panic and hit the brakes until they are sure
that its clear to go
