the overall width of a locomotive or tractor shall not exceed 2.9 metres unless it is used for or in connection with the carriage of a load on a trailer which exceeds that overall width, being a load which can only be carried on such a trailer;
notwithstanding anything in paragraphs (c) and (d), the overall width of a heavy motor car, locomotive, tractor or trailer shall not exceed 6.1 metres;
where, in relation to the load being carried by a vehicle, there is a lateral projection on one or both sides of the vehicle the overall width of the vehicle together with the width of the projection, or, as the case may be, of both projections shall not exceed 6.1 metres;
