Beware of Shoulder Edge Drop Off
I would like to warn you of the dangers of our highway shoulders. These highway shoulders are more commonly referred to as “pavement edge drop off” by the Federal Highway Administration. Information contained in California State design and maintenance standards reveal that the paved edge/shoulder of any given roadway should be built and maintained in a flat (flush) manner with its adjacent unpaved shoulder. A dangerous shoulder edge drop generally results from improper road maintenance. These roadway shoulders become unsafe and dangerous when a motorist leaves the roadway and then tries to re-enter over a shoulder edge drop off. What usually occurs is that the motorist needs to increase steering in order to come back up onto the pavement edge drop off to re-enter the road he pulled off of. When the motorist is successful at mounting the pavement edge drop off, the motorist instantly finds himself back on the road with an increase in steering motion. Couple this with the high speed that is necessary to merge back onto a highway and you have a recipe for disaster in that the motorist is unable to react to the movement caused by increased steering input and the car veers off the roadway opposite the pavement edge drop off and gets seriously injured.
