In today's world life on the roads have changed so much, it used to be too much drinking over the wheel, not any more. Drugs have taken over so much that it is so alarming. People not knowing to take them & drive & not realizing what it does to their brain in the meantime. When the damage is done, it is too late that an accident & a life could have been prevented. I wish that now how our lives have changed so much due to other reckless people's behavior, that every driving vehicle should not start without having a clear drug testing solution of some sort to start the vehicle up. I believe this will prevent accidents & lives if a vehicle won't drive if you are affected. What do you feel if this can happen?
