Haw. Rev. Stat. § 46-16
Any provision of law to the contrary notwithstanding, any county and its authorized personnel may impose and enforce traffic regulations and place appropriate traffic control devices, and may enforce chapters 249; 286; 287; 291; 291C; 291E; 431, articles 10C and 10G; and 486, part III on the following categories of private streets, highways, or thoroughfares, except private roads used primarily for agricultural and ranching purposes:
[L 1973, c 137, §1; am L 1988, c 358, §1; am L 1995, c 173, §2; am L 2010, c 153, §2]
While the fact that the privately owned road was platted on a subdivision map, that §265A-1 authorized counties to repair and maintain private streets, and this section authorized counties to regulate traffic on private streets, and each of these factors was significant in determining which party or parties had control of the private roadway, appellate court erred in concluding as a matter of law that defendant property owners did not control roadway and thus had no duty to maintain, repair, or warn of a dangerous condition; the issue of control of the roadway was a question of fact for the jury. 103 H. 385, 83 P.3d 100.
