But in case you didn't know first responders are trained to look for these and adjust accordingly. That's why we have one up, nothing to do with cautious driving.
To add what the person below/above said me: its not a great idea either because baby on board can indicate to thieves that it might be a decent car to steel from due to you likely being occupied by the baby
To be clear, it's not a sticker to say you can or cannot ram into said car. It's for when you notice an idiot driving 10 mph under the speed limit and before you tailgate them, you see understand the parents are struggling to hold it together and you give them some slack.
