The objective is safe road user behaviour, achieved by a predictable roadway environment through the consistent, appropriate application of traffic control devices. Further purposes of the OTM are to provide a set of guidelines consistent with the intent of the HighwayTraffic Act and to provide a basis for road authorities to generate or update their own guidelines and standards. The OTM is made up of a number of Books, which are continuously updated.  \nThe OTM is directed to its primary users, traffic practitioners. The OTM incorporates current best practices in the province of Ontario. The interpretations, recommendations and guidelines in the OTM are intended to provide an understanding of traffic operations and they cover a broad range of traffic situations encountered in practice.They are based on many factors which may determine the specific design and operational effectiveness of traffic control systems. However, no manual can coverall contingencies or all cases encountered in the field.Therefore, field experience and knowledge of application are essential in deciding what to do in the absence of specific direction from the Manual itself and in overriding any recommendations in this Manual. The traffic practitioner’s fundamental responsibility is to exercise engineering judgement and experience on technical matters in the best interests of the public and workers. Guidelines are provided in the OTM to assist in making those judgements, but they should not be used as a substitute for judgement. Design, application and operational guidelines and procedures should be used with judicious care and proper consideration of the prevailing circumstances.  \nIn some designs, applications, or operational features, the traffic practitioner’s judgement is to meet or exceed a guideline while in others a guideline might not be met for sound reasons, such as space availability, yet still produce a design or operation which may be judged to be safe. Every effort should be made to stay as close to the guidelines as possible in situations like these, and to document reasons for departures from them.  \nTEMPORARY CONDITIONS · BOOK 7  \nCustodial
