There’s a busy road near where I work,

There is a crossing, half way down with a priority to traffic, going towards town,

but I have been in situations where on coming traffic also drive at the gap !!  

but when I flashed him, ( my headlights ) He stopped and told me to use my eyes,

 ( i shall not tell you my response ! )

   My collegue had the same experience, and the woman driver actually shouted through the window saying that the sign was optional !!!  OPTIONAL ???

  Perhaps people just do not know the high way code ?
