PassCount Down Markers
Where: On the left-hand side of any road, in the last stretch before an exit. Three bars at 300 metres, two at 200, one at 100.
Purpose: To mark the remaining distance to an exit in a way you can read at speed without taking your eyes off the road for long. The number of bars falls as the exit approaches.
Action Required by Driver: Use them to judge your speed and lane, not to decide whether to exit — that decision belongs further back. If possible, enter the exit at the speed the road allows rather than braking hard on the freeway itself. If you see one bar and you are not in the left lane, carry on to the next exit.
