Study Notes
Road Traffic Collision Management
- Coning on motorways and dual carriageways requires distances based on the speed limit, with a minimum distance for each closed lane.
- The aim of coning is to gradually direct traffic away from an obstruction to prevent further collisions.
- Complete lanes should be coned, never part of a lane, and isolation between lanes of live traffic should be avoided.
- Coning begins at the taper point, and in stationary traffic, it may be necessary to clear coned areas starting from the police vehicle.
- Preferably, the hard shoulder should remain open for emergency service access.
- Only the rear police vehicle in closed lanes should have full emergency lighting activated to serve as a ‘line of defense.’
Police Procedures and Safety Protocols
- The removal of cones and signs should be done systematically, starting from the incident site towards the warning signs.
- Officers should work facing oncoming traffic while within the coned area.
- Speed limits correlate with stopping distances and required coning distances, ranging from 15m to 100m behind police vehicles depending on speed limits (30mph to 70mph).
- Life-threatening injuries at a scene may necessitate the deployment of a Senior Investigating Officer (SIO) and a formal investigation log.
- Police must coordinate with other emergency services for scene management and to maintain safe traffic flow.
Electric and Hybrid Vehicle Hazards
- Electric vehicles (EVs) contain high-voltage lithium-ion batteries, typically encased in steel, raising distinct hazards.
- EV features include charging flaps, absence of exhaust pipes, unique dashboard controls, and non-standard parking mechanisms.
- Officers face significant risks including electric shock, potential fires that can reignite, and exploding batteries from vehicle damage.
- Precautions include avoiding the use of EVs for cover in armed incidents and assessing vehicle types before engagement.
Incident Response Protocols
- Do not approach unidentified vehicles without prior consultation with recovery services if life isn't immediately endangered.
- Firefighting with water or foam on EV fires is ineffective and can exacerbate hazards; small extinguishers are inadequate.
- Risks of re-ignition after extinguishing could persist for weeks; immersion in water is not a reliable safety measure.
- Under no circumstances should 400V orange cables or earth straps be cut to avoid electric shock hazards.
