Speed and the flow of traffic
When it comes to driving on multiple lane divided highways (freeways or limited access roadways) the safest speed is not always the slowest nor the posted speed limit. This makes for a conundrum. Obey or not to obey the speed limit on divided highways is often the question we have to ask ourselves as drivers. I offer no simple answer. The “Solomon Curve” and ensuing research argue the greater the difference between a driver’s speed and the average speed of traffic (below and above the average speed) the greater likelihood of being involved in a crash. That said, nothing relieves a driver from due care while operating his or her vehicle.
In all states and DC, there is the basic speed law or its equivalent, which says: “No person shall drive a vehicle upon a highway at a speed greater than is reasonable or prudent under the conditions, including actual and potential hazards then existing.” (Uniform Vehicle Code 11-801-Basic Rule)
