There are design specifications for the minimum sight distance (distance to see an approaching vehicle measured along the roadway from the intersection of the two roadways) that a driver stopped at a stop sign must have to safely enter a roadway where vehicles do not stop. Values in the table below are for safe entry to cross the roadway (not to turn onto the other roadway but to cross) where vehicles do not stop.
