Liverpool (WSYR-TV) - The over-height vehicle detection system was activated on the Onondaga Lake Parkway two years ago Saturday as part of the state's effort to prevent something like the deadly Megabus crash from happening again.
It's hard to measure how many truck and bus drivers saw the warning signs or knew about the commercial vehicle ban before they ever got onto Onondaga Lake Parkway.
What we do know is that almost 1,000 drivers did get on the roadway with vehicles over 11 feet tall, breaking laser beams on each end of the road, triggering the over-height vehicle detection system.
That system sets off a series of flashing lights and message boards telling drivers of the danger ahead.
An average of more than once a day, the system has been set off since going into action two years ago.
State Department of Transportation spokesperson Gene Cilento said, “It’s still a little scary that that many people, that many drivers can not notice the signs."
Only once was the system unable to prevent a crash. A box truck slammed into the bridge earlier this year, although nothing was hurt, except the truck.
“Because you need to have a driver react to something, there's always that question that he or she won't. That's the problem, it’s not foolproof. It’s much better than it was but it’s not completely foolproof,” Cilento said.
He says the detection system is just the high tech portion, of which this sign is the last piece, but its part of a bigger picture approach to the problem that includes road markings, several signs, and markings on the bridge itself, along with a ban on commercial vehicles on the roadway.
He says for the moment the state has done about all it can to alert drivers to that low bridge.
