CTT’s policy in the 1990s was not to sanction new courses that required a dead turn in the road. That however was in the days before CTT introduced the strict requirement that all courses (both those used for open and for club events) MUST have a risk assessment. The CTT insurers say that they are happy to leave CTT to manage its risk, and for so long as the claims record remains good that is expected to remain the case. As such, provided that a full and proper risk assessment is carried out, and it is considered safe to have a dead turn, then this shouldn’t be a problem.
