Meet the CMDL; a light for texting and talking on the phone while driving
For the average Joe, basically, CMDL is a fluorescent light located bang in the middle of your brake light that explains others that you are though capable of driving, but your focus is also on other things. Say, if you received a call you cannot miss while driving on a highway, you would be in for jeopardy. Neither can you slow down pull over nor can you miss the call. So here’s what you do. You switch on the CMDL, which warns the other drivers of your situation and they can drive more carefully.
