Near/side, often abbreviated to N/S is side nearest the pavement (sorry sidewalk) so for your your right if sat in the car lookin forward, the opposite is Off Side (O/S) this can be confused with Off Side a rule in Football (not American football), in this instance it means the side furthest away from the pavement (in your case your left). By the way I was assuming you had a left hand drive car for driving on the wrong side of the road (for us).
