Unfortuanately with a yellow box junction you should not enter unless the exit is clear.
I am aware that no one wants to wait that long because the car behind will start honking the horn but the alternative is paying the ticket.
If yer nicked my keys just because you had the hump i`d rip yer **** off and eat it
mines worked up to 27.4 since i got it and just seems to stay there.
I use it at weekends on decent runs though so no pissing about in traffic going to work.
