Emergency crews responded to a three-vehicle accident near the S-curve in Gardnerville at about 3:35 p.m. Wednesday.
Witnesses on scene said three cars were involved in a rear-end-type collision resulting in moderate damage.
One of the cars was reportedly leaking fuel, prompting a hazardous materials team to be called to the site. The hazmat team was later called off, as existing teams believed they could handle it.
First-responders indicated there was at least one patient needing medical attention, and another person refusing treatment.
Motorists should use caution in the area.
