The U.S. Department of Transportation (US DOT) has many free traffic safety mobile apps that can help you stay safe on the roads. Their SaferRide app has been available for a while now, but they have since developed a few more apps to help motorists and consumers improve roadway safety. With these apps, you can find a safe ride home. check safety ratings on vehicles, get recall information, and check bus safety performance and operational compliance. You can even check to see if it’s safe to fly your drone or model airplane at a particular place and time. Below is a list of US DOT’s current mobile apps.
