Idk Phil, count the sides of the back of that sign. Log in to Reply Damn that makes so much sense too Log in to Reply Seriously? All traffic signs have a unique shape for this reason Log in to Reply My driving instructor told me he once had a student fail the exam because they didn’t stop for a stop sign that was obscured by an illegally parked truck… Because he could have seen the backwards one across the street Log in to Reply ….. In what possible scenario would people driving one way down a street have to stop but people on the opposite side of the same street not have to?
