The correct answer is false.
It is false that you may exceed the speed limit when passing another vehicle.
You must always respect the speed limited signals in highways or any kind of road you travel. If you want to pass a vehicle, do it under the law. Take the left lane, signal the other driver and proceed with precaution. It is not true that myth that you may exceed the speed limit when passing another vehicle as long as once the pass has been executed you return to the allowed speed limit.
