If you are driving on a 65mph highway, please do not run 50. You will cause back up and traffic on the road. Move over the shoulder if there is one. And let the vehicles behind you pass. If you really are a slow driver, please do the same thing. If you are having an emergency, please turn on the signal. It only takes a 2-3 seconds to push the button and pull over.
Please be a responsible driver. You are not the only motorist in the world. I’m just saying. And it’s a friendly advice.
