Not quiteCorrect answer: A — No motor vehicle of any kind may go beyond this point
The words NO MOTOR VEHICLES close that road or path to motorised traffic altogether, which is why the sign appears at trails, plazas and pedestrian streets. Walkers and cyclists are unaffected unless their own prohibition signs are posted.
Reading it as a restriction on cars only. The wording covers every motor vehicle, motorcycles and mopeds included.
