Why is the traffic light on the off-side of the road not facing down the road towards on-coming traffic?
The signal on the off-side of the road (referred to as the secondary signal) is directed slightly towards the vehicles waiting at the stop line. Drivers of vans and lorries have a problem seeing the nearside signal when stopped at the stop line. The nearside signal is the important one for drivers approaching the signals as the off-side one can be obscured by traffic travelling in the opposite direction.
