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.
Laws prohibiting careless or reckless driving are in effect on Montana roads. These laws allow motorists to be stopped even if they are not exceeding the posted speed limit, if the speed at which they are traveling is considered too fast for conditions or dangerous to others on the road.
