This note briefly responds to some of the complaints against heavy lorries. With regard to noise, it is argued that if the motor is well maintained and the vehicle properly driven, the noise is no greater than from other road vehicles (cars, motorcycles, mopeds). Precise regulations exist at a european level regarding maximum noise levels for commercial vehicles, and present limits are being reviewed with a view to further reduction. With regard to exhaust emissions, it is pointed out that though more visible, diesel fumes are less pollutant than petrol fumes, and that regulations also exist regarding exhaust emissions. Regarding the slowness of heavy vehicles and the difficulty of overtaking them, the solution appears to be the separation of slow and fast traffic. On the question of road damage, the note points out that all types of traffic contribute to wear and that climatic conditions (frost, snow, storm, heat, etc.) are large contributory factors. The vibration effect of heavy traffic on the substructures of ancient buildings is claimed to be hypothetical and not entirely proved, and in any case the solution would be to re-route the traffic. /TRRL/
