Question

If you are stopping at an intersection with stop bars you should stop before: A.Your front wheel wells cross the line
B.Your front tires cross the line
C.Your front bumper crosses the line
D.You lose sight of the line

Answer 1

C. Your front bumper crosses the line

Answer 2

Answer:

Suppose we have a line  Say A at one side and B on the other side

                    A--------B

The car is stopping at an intersection wit stop Bars that means the car is crossing A if coming from left and crossing B if coming from right

That follows when front bumper crosses the line

Option A and B is discarded because Wheels are behind bumper so, if bumper crosses then the wheels will cross.

Therefore, Option C is correct.
