UCI CYCLING REGULATIONS  2.2.017 (N) A zone of at least 300 metres before and 100 metres after the finishing line shall be  protected by barriers. Any situation in which it is impossible to respect the distance of  100 metres after the finish (without materially affecting safety) in particular at a mountain  top finish, requires the organiser to install the maximum number of barriers possible  according to the topography of the site. This decision is taken under the organiser's  responsibility.  In addition, this 400-meter zone shall be accessible exclusively to representatives of the  organiser, riders, paramedical assistants, sports directors and accredited press  personnel.  The 400 metres of barriers thus formed must be continuous and the barriers firmly  attached to each other. No gaps are allowed (in particular at the finish line). A gate  system must be installed at least 100 metres after the finish line to allow organisation  personnel to pass through the barriers.  The use of lightweight barriers (e.g. plastic) to cordon off the event route is prohibited,  including after the finish line. The barriers must be weighted down so that they do not  move in strong winds or when subject to pressure by spectators or other forces.  The event safety manager shall pay special attention to the final section of the race route,  and the final hundredth meters before the finish in particular and shall ensure that the  safety conditions are observed. This is especially important for events likely to finish in  bunch sprints.

Medical care  2.2.019 Medical care during the race shall be administered exclusively by the doctor(s)  designated by the organiser of the race from the moment the riders enter the checking  area at the start until they leave that at the finish.  (text modified on 1.01.05).  2.2.020 Should any major treatment be necessary on mountain passes or hill-climbs, the doctor  shall stop to administer that treatment. The doctor shall be responsible for his car and its  occupants and will tolerate no assistance whatsoever being rendered that might help a  rider receiving treatment to remain in or return to the bunch (by towing him or allowing  him to ride in the wake of the vehicle, etc.).
