Driving hazards in 1934, when British traffic rules and road designs were still evolving.
Tramcars are built with a considerable amount of overhang at each end, and for that reason the ends swing out for some distance when they round a curve. Do not pass a tram when it is nearing a corner or crossing a junction, as its rear platform may strike the side of your car. It is not safe to rely on the driver giving the correct hand signal, and even if he does so the bulk of his vehicle will hide his hand from you. Never follow a tram closely for it is fitted with very powerful magnetic brakes and should it stop suddenly you may be unable to avoid a collision.
Some towns have by-laws that compel all traffic to stop when a tram stops, so as to avoid danger to any passengers who may be entering or alighting from it. In other districts the procedure is left to the discretion of the motorist who may stop, proceed cautiously or pass the tram on the off side. Of these three alternatives the first is the safest, for among the tram’s passengers there may be an old person or an irresponsible child. Passing round the off side of the tram has its dangers as one may meet another tram proceeding rapidly in the opposite direction.
It is always inadvisable to motor along a tram track, for tramlines, especially if they are wet, are most “skid-provoking.” Often, too, the lines are worn to a sharp edge which cuts the tyres. If you have the misfortune to get your wheels caught in the tram track (as in the case illustrated), pull out gradually.
Grip the wheel firmly, but gently, and change the direction of motion as gradually as possible. Avoid use of the brakes, take your foot off the accelerator and press down the clutch pedal so that the car rolls along, for rolling road wheels, that have no power transmitted through them, do not skid.
