CHAPTER XI HIGHWAY ACCIDENTS AND THEIR MITIGATION It may be true that accidents are commonly the result of disorder, but as there seems to be no panacea for disorder, accidents cannot entirely be prevented. The best thing that can be done at present is to arrange everything connected with the road so that the chance of accident will be kept as low as it is possible for imperfect humanity to keep it. Transportation accidents have always occurred and probably always will occur. In the early days of the railway such papers as _Harper’s Weekly_ ran weekly illustrated accounts of railway accidents. If it was the intention to induce the people not to patronize the train service it utterly failed. To prevent shipping accidents the Government has spent millions in lighthouses and water-front protection. Great quantities of money have been spent to make safe river transportation. Elaborate national and international codes of rules for navigation have been adopted. Laws to regulate railways have been passed. The newest form of transportation, aviation, has already been a subject for the law makers’ wisdom.
