Ever wondered who decides on speed limits? We’ve done the legwork to find you some answers. We did too. So we've done some digging and figured it out.
Speed limits are set by state and local governments. Most states have a maximum allowable limit–70 MPH in PA–that determines the upper limit for speeds on highways and the like. From that point, officials examine where the limit needs to be set. There are specific regulations for certain areas, such as residential areas (25 MPH), business districts (30 MPH), and other roads (generally 55 MPH). These limits are referred to as “statutory limits” and are based on the safest maximum speed under which vehicles can operate under ideal conditions.
If you ask a qualified professional how speed limits are set, such as a transportation safety engineer, you’ll likely hear the term “85th percentile.” This term comes from the determination method that takes how we drive into consideration. Though it may come as a surprise that our impulses as drivers are taken into account, they are a factor in setting limits. If speed limits are set too high, drivers might ignore them and drive slower; too low and drivers might disregard them and drive fast anyway.
It’s important to remember that speed limits are set for driving in ideal conditions, so when the weather is rough it’s the driver’s responsibility to slow down to appropriate speeds. Conditions such as fog, snow, or rain can call for greatly reduced speed. When in doubt, take your time. It’s always better to be late and unharmed than rush your way into a tricky situation.
