YELLOW lines are there to keep the roads flowing freely. To allow any grace period (LT, July 30) would have a catastrophic effect on traffic flow.

In many places it would be a case of one out, one in, resulting in vehicles being parked on them continuously.

If any parking at all were allowed, one would have to ask what was the point of them in the first place. A crazy idea!
