You want to pass a slow vehicle on a two-lane road. Within what distance of an intersection, bridge, tunnel, or railroad crossing is passing NOT allowed?

Why

Passing needs a long, clear stretch of road, and the places where other traffic can appear suddenly are exactly where the handbook forbids it: inside 100 feet of any intersection, of a bridge, a tunnel, a railroad crossing or anything else it treats as a hazardous area, plus crossroads and driveways, plus anywhere your view runs out. For a hill or curve, the handbook wants the crest or bend at least one-third of a mile ahead before you commit. Fifty feet is too little to mean anything at road speed; 500 feet is the headlight-dimming distance, not a passing rule. And whatever the distance, you may only pass when you have enough space to return to your lane.
