It's not like most of us are completely helpless when it comes to crossing streets. We know when it might be unsafe, and if a bus is approaching and you tell me to go, I wouldn't. But it might help a lot to actually reach the right street/find the second inaccessible traffic light/etc. You could also make sure that you describe the potential route to be taken, which might make it safer still. Sometimes a "A little left" or "You're turning onto another road" can be very helpful, which I assume was more or less the case. :)
