Section 51. Posting of notice regarding compensation

Every employer who has
  complied with section fifty of this article shall post and maintain in a
  conspicuous place or places in and about his place or places of business
  typewritten  or  printed  notices  in  form  prescribed by the chairman,
  stating the fact that he has complied with all the rules and regulations
  of the chairman and the board and that he has  secured  the  payment  of
  compensation  to  his  employees and their dependents in accordance with
  the provisions of this chapter, but  failure  to  post  such  notice  as
  herein  provided  shall  not  in any way affect the exclusiveness of the
  remedy provided for by section eleven of this  chapter.  Every  employer
  who  owns  or  operates  automotive  or  horse-drawn vehicles and has no
  minimum staff of regular employees required to report  for  work  at  an
  established  place  of  business  maintained  by such employer and every
  employer who is engaged in the business of  moving  household  goods  or
  furniture  shall  post  such  notices in each and every vehicle owned or
  operated by him. Failure to post or maintain such notice in any of  said
  vehicles  shall  constitute  presumptive evidence that such employer has
  failed to secure the payment of compensation. The chairman  may  require
  any  employer  to  furnish  a  written statement at any time showing the
  stock corporation, mutual corporation or  reciprocal  insurer  in  which
  such  employer  is  insured  or  the  manner  in which such employer has
  complied with any provision of this chapter. Failure for a period of ten
  days to furnish such  written  statement  shall  constitute  presumptive
  evidence that such employer has neglected or failed in respect of any of
  the  matters  so  required.  Any  employer  who fails to comply with the
  provisions of this section shall be required to pay to the board a  fine
  of  up  to  two hundred fifty dollars for each violation, in addition to
  any other penalties imposed by law to be deposited  into  the  uninsured
  employers' fund.
