The accident happened on Honoapiilani (30) Hwy just north of Kaanapali Parkway and just south of the Kualapa Lp. overpass. The northbound road rises about 100 feet between those two points. The road here is four lanes wide with a three foot wide painted divider - the heavy solid diagonal yellow stripes between two parallel courses of double yellow lines favored by Hawaii's highway department. The speed limit is 40 mph. Traffic never moves at the speed limit - 60 mph is typical when the road is clear. The road is poorly lit at night.  Another accident occurred 100 feet north of this spot on July 24. I've been driving this stretch of road several times a day for 20 years and have never seen traffic enforcement here. The road here, as could pretty much most of Honoapiilani Hwy, would be inexpensively improved by the installation of an actual physical divider between lanes. Unfortunately, the safety of Maui's roads is not a concern for either elected officials or the HI Highway Department.
