Observation, Speed & SpaceStandalone practice
You plan a long trip on Oklahoma turnpikes. What is the highest speed limit that Oklahoma law allows on a turnpike section where signs post it?
Correct answer: 80 mph
Why
Many turnpike sections have lower posted limits, and the posted sign always controls. Even at 80 mph, the basic speed rule applies, so slow down for heavy traffic, rain, fog and darkness. At 80 mph the total stopping distance is several hundred feet, longer than a football field.
