A lot of people have been asking whether or not the speed limit changes when they see the posted speed limit sign or past it?
Question: When a road’s speed limit changes, let’s say from 45 mph up to 60 mph, does the increased speed limit take effect once you can see the new sign or after you pass the sign?
Speed limit signs “shall be located at the points of change from one speed limit to another.” Therefore, drivers should not accelerate until reaching an increased speed limit sign.
Ok, we can already hear some grumbling about that answer. Delving deeper into the issue a speed limit can change just because the road spans jurisdictions. When going from a city into the county, the speed limit may change to reflect the jurisdiction’s default speed limit. A speed limit also will increase or decrease due to road characteristics. Many factors determine the appropriate speed for a road; a few examples include road surface and width, frequency of curves, driver visibility, traffic density, urban vs. rural, pedestrian traffic, and number of driveways entering the road.
For example, the speed limit on Highway 30 in front of Chobani's is 45 miles per hour. That speed limit doesn't change to 60 while traveling east bound until passing by all points of entry/exit going into Chobani's.
In front of Bickel Elementary while the lights are flashing, the speed limit is 20 mph. After exiting the school zone, the speed limit increases to 35. If you start accelerating once you see the 35 zone, but still in the 20 mph school zone you risk 4 points on your record and a $156.50 school zone citation. Same holds true in front of Chobani, if you speed up before actually passing the 60 mph sign, you risk a $90.00 citation for basic rule and 3 points on your record.
