Legally Licensed Food Vendors are issued a department of health permit which by law must be displayed in a conspicuous location within the eatery. It is against the law for an unlicensed individual/entity to advertise or solicit commercial services without the proper legalities.
Presently there are numerous unlicensed tour operations advertising illegal tours online. TripAdvisor has (35) Listings Under Private Tours on Maui, at least (18) are unlicensed or illegal. Of the (35) Restaurants logged along the Road to Hana on Tripadvisor, at least (5) lack a health permit and therefore considered unlicensed commercial activity. There is a lack of regulation presence by the public utilities commission and the department of health which festers the black market that currently thrives. This creates overcrowding, a dangerous predicament for the general public and an unfair competitive advantage for the illegal operators at the expense of legitimate, licensed companies. Although many of these unlicensed ground tours have stellar reviews, great employees and some have been operating for several years - the fact still remains that they are operating illegally, likely lacking other adequate insurances, permits or certificates and subsequently possibly miscounting the appropriate scope of taxations in the realms of both government and community give-back.
You can see if a tour operator is licensed via the PUC website at www.puc.hawaii.gov in the Advanced Docket Search section.
