New York State Governor David Patterson has a headache hard to imagine: Truckers using Global Positioning System (GPS) satellite navigation are crashing into bridges. The reason: They use GPS to find routes that save time, but are not truck-safe--at times, even when carrying hazardous materials. In the past 15 years, New York State has seen an astounding 1,4000 bridge accidents due to trucks (to be fair, GPS is of more recent vintage, so many, perhaps most, of the crashes were pre-GPS). This is 93 bridge hits annually, nearly two per week.
A GPS fix would be to program, state by state (it happens elsewhere, too), restrictions into route options, so that truckers cannot find the routes. This might help, but experienced drivers would still find the routes. Criminal prosecution of anyone caught knowingly transporting hazardous materials along prohibited routes might help more.
