You're driving the orange car on an urban street and you want to turn right at this intersection. Is it safe to go? You're driving the orange car on an urban street and you want to turn right at this intersection. Is it safe to go?

  • A. Yes - the green car is quite far away

  • B. No - the green car is too close

    The correct answer is B
     
    Correct. The green car will be covering around 14 metres per second at 50km/h. The average car is around four metres long, so the green car is only around a second away from reaching you (there are about four car lengths). Therefore it's not safe to turn. Ideally you should have at least four seconds to be safe.
