E-toll Shesha lane

I recently purchased an E-Tag which works brilliantly and is such a time saver when there's a long queue at the tolls, EXCEPT when there's a car without an E-Tag in the "tag only" queue! Everyone then has to reverse to let the car out of the queue. The shesha lanes for "tags only" are not clearly sign posted at all. The signs are pale orange with white writing . They would be much more visible if they were lumo orange/yellow or bright red with white writing. The sign showing which is the shesha lane should also be placed further back as most people only see it when they have reached the front of the queue.
