Penn Hills Fire Department No. 7 has added transponders to their fleet to help alert people using navigation apps.It comes less than a week after a South Strabane fire truck was hit by a car while responding to another crash Sunday. First responders say dangerous situations like that one are all too common.Chief Bill Jeffcoat, of Penn Hills Fire Department No. 7, tells Pittsburgh’s Action News 4 the new devices are designed to give drivers time to slow down or move over when they are approaching an accident scene.“We had a motorist side-swipe a tractor trailer trying to move over to that lane, so they don't hit the fire truck — that was the straw that broke the camel's back,” Jeffcoat said. Jeffcoat said the HAAS alert system sends out a warning and gives drivers a heads up.“A lot of us have Google Maps or Waze apps on our phone, it will project to those apps, telling us that there is a vehicle off to the side of the road, or there is an emergency vehicle up ahead or an accident ahead,” Jeffcoat said.Jeffcoat said his fire department is the first one in Allegheny County to use HAAS transponders.“Any little thing that we can do to make our firefighters, our vehicles, and motorists safe, then it's a bang for our buck,” Jeffcoat said.With this advanced warning, Jeffcoat and agencies, like PennDOT, expect drivers to follow the state's Move Over Law.“Anytime that you are out on the roadway, and you see an emergency scene on the side of the road, your job is to make sure you move over one lane if possible,” PennDOT District 11 Safety Press Officer Yasmeen Manyisha said. If that can't happen, Manyisha says slow down.“If you are unable to move over a lane, you want to make sure that you are slowing down. No more than 20 miles per hour under the speed limit, but that gives you a nice cushion area where you can slow down safely, respectively, and give them the distance and the space that they need — that can be the officer who is pulling someone over on the side of the road, that can be the car on the side of the road who might have a tow truck, or even if they are just broken down without a tow truck, our PennDOT crews,” Manyisha said.Violators of the Move Over Law face a $500 fine for the first offense, a $1,000 fine for the second and for the third offense, a $2,000 fine, along with a 90-day suspended license.“We really need people to slow down and pay attention to what is going on because you really have to expect the unexpected,” Manyisha said.“Everybody is in a hurry. Everybody has to go, go, go. It's like common sense is left behind. Those secondary vehicle accidents are common things. Whatever we can do to try to mitigate that or eliminate it, is our goal,” Jeffcoat said.Jeffcoat said they purchased five transponders. It will cost them about $2,000 a year to operate.
