Zoloft (sertraline) is an antidepressant in a group of drugs called selective serotonin reuptake inhibitors (SSRIs). The way sertraline works is still not fully understood. It is thought to positively affect communication between nerve cells in the central nervous system and/or restore chemical balance in the brain.
Montana's current nighttime speed limits are 65 m.p.h. on Interstates and 55 m.p.h. on two-lane highways, and those are not affected by the court's ruling.
The maximum speed limit is 110 Km/h, but this limit is further reduced to 90 Km/h in mountainous areas and near urban centres. All road signs are in green with white text and are reflective at night with the exception of Federal Highway signs, which are blue with white text.
