I put it to you that if the stop line is moved back by say 5 metres to make a "bike box" but the traffic lights have not been moved, the stopping distance has been shortened by 5 metres unless the traffic light "amber" phase has been amended to take this into account. While this may not affect stopping in a car it certainly does in a bus weighing up to 18 tonnes.
Roy, that makes no sense. When the light turns amber, you have 3 seconds in which to stop. The position of the light source makes no difference to the timing of the lights.
sorry that's just wrong. Roy is correct.
For arguments sake, let's imagine the new line is moved 100m back up the road. when the lights turn amber you could be at, approaching or past the line.
so either the timing has to be changed to reflect the distance or the lights need to be moved to the new line.
back on topic, I suggest the OP might argue that stopping, albeit over the line, due to the safety of the passengers was a better option than continuing across the junction which MAY have had the possibility or resulting in an accident.
