The tendency of drivers of all forms of motor vehicles is, and I suppose always will be, to drive too fast, exceeding the speed limit, whether the nature of the road and other circumstances allow or not. The condition of the roads within the war zone is such that to drive too fast spells broken springs, to mention only one result. Severe disciplinary action has become necessary, and with this in view Assistant Provost Marshals have a way of employing military police with stop-watches in the old and approved method of the Portsmouth and Brighton roads. I heard of one trap which was set on a little stretch of road that was within view and under enemy observation. At this particular spot the military police made some easy captures. All roads are under the supervision of the military police, who direct all traffic. Each army issues a Traffic Map of the area in which it is operating, and this is in possession of all officers in charge of convoys. On it, roads over which, owing to their broadness, traffic is allowed to travel from both directions are marked in a certain way; narrower roads, over which it is only allowed to proceed one way, are otherwise indicated on the map. This road control, though often an inconvenience, necessitating a long detour, in some cases, to reach a certain place, in order to avoid going against the orders, is absolutely essential. Without it, blocks in the traffic, ditching in narrow roads, and consequent delay, would be of frequent occurrence.
