We can’t help but notice them during our daily drive to work or to the shopping mall or even on a visit to friends or relatives. Those bossy signposts like STOP or Yield or even ones that tell us there’s a detour ahead. They may seem to be pushy or authoritative and they are, but with a purpose.
These custom signs are put there by regulatory laws that are meant to keep us safe. When you take your written driving exam in most states you will be presented with a variety of shapes that depict traffic markers that are in use.
