Safe Driving is important. What products are available to help the deaf or hearing impaired to know when a siren is going on while driving? Specific -- to alert us where to look and to pull over if needed. This is for Police, Fire, and Emergency Vehicles. Sometimes they pull up and I really am shocked to see them. Sometimes I can tell there is a need to pull over, but when I don't know -- gosh that is nerve racking. What do you do?
