PA 550 Speed Limit

Someone has set up a petition on change.org to increase the speed limit on PA 550 to 55 m.p.h. The petition states:

“The speed limit on PA route 550 south is too low and should be increased to 55mph. A large portion of motorists already consistently drive over 50mph on 550 daily and by increasing the speed limit the road would be made safer as the speed limit would more closely resemble the speed motorists actually travel on the road. This would also likely eliminate most tailgating and strings of traffic behind someone going ‘exactly 45 THE WHOLE WAY DOWN 550.’”

As of this posting, 22 people have signed the petition.

PA 550 is a rural highway that runs from Zion, PA to near Tyrone, PA. The petition does not state which section of the highway it is addressing, or mention that the current posted speed limits are not consistent along its length (35 m.p.h. in Stormstown, 25 m.p.h. in Bellefonte, and above 45 in Huntingdon County). Nor does it mention the no passing zones for much of its length, the limited sight distances, sharp curves, the presence of slow moving farm equipment, or wildlife crossing the highway.

The argument stated in the petition is a logical fallacy. Just because “everyone” is exceeding the speed limit is not a valid argument for increasing it. As stated above there are too many potential hazards to warrant an increase to 55 mph.
