If we encounter a STOP sign at an intersection, what must we do?
A)Always stop to give way.Correct
B)Stop to give way only if a vehicle is approaching.
C)Stop directly where we have enough visibility, being able to cross the stop line if there is one.
The STOP sign requires every driver to stop their vehicle at the next stop line or, if there is none, immediately before the intersection, and to give way to vehicles travelling on the road being approached.
If there is not enough visibility from the place where you have stopped, you must stop again at the place where you have visibility, without endangering any road user.
