On the M-12 "Vostok" highway bridge over the Oka River, interdepartmental drills were conducted.

Interdepartmental drills to eliminate the effects of a serious accident were held on the 322nd kilometer of the M-12 "Vostok" highway near the bridge over the Oka River. They were attended by specialists of Russian Highways State Company, employees of the Ministry of Emergency Situations (EMERCOM), State Automobile Inspection, medical institutions of the Vladimir and Nizhny Novgorod regions, the Center for Disaster Medicine and contractors.
The legend states that the unified emergency services number "112" received a notification concerning a significant accident early in the morning.   On the bridge over the Oka River, two passenger cars, a passenger bus and a gasoline truck carrying fuel and lubricants collided.   As a result of the accident, the traffic towards Kazan was completely blocked resulting in a traffic jam of more than four kilometers.
According to the scenario, ten people were injured, two died. One of the passenger vehicles caught fire, and there was a threat of fuel spillage ignition Units of the EMERCOM of Russia for Nizhny Novgorod Region and emergency medical teams were urgently dispatched to the site. Rescuers began putting out the flaming truck, cooling the fuel tanker and carrying out rescue operations. Additional medical crews - an emergency rescue team from Vyksa, and additional Russian EMERCOM units for the Vladimir region - contributed to the removal of the accident's aftermath.  
Information about the accident was promptly transferred to the Situation Center of the Nizhny Novgorod branch of State Company. After assessing the situation, a decision was made to organize a traffic diversion in the opposite direction. For this purpose, road services started dismantling metal barrier fencing on the approaches to the bridge and preparing a temporary traffic scheme. Thanks to specialized equipment, the rescuers were able to swiftly remove the victims from the damaged vehicles and transfer them to medical personnel.
The outcomes showed that all services' interactions were well-coordinated and productive.   Experts developed the protocols for managing traffic in the event of a protracted road closure and the algorithms of action in the event of a mass collision involving cars transporting hazardous materials.   Such drills make it possible to assess how prepared services are for emergencies and to practice how all participants—from dispatchers to rescuers—interact.   After all, in a real-world scenario, coherence and quickness are what guarantee road safety and assist save lives.
