RESPONDERSAFETY Blocking
Procedures at Roadway Incidents
When the police cruiser arrives, where should it park to create a safe work zone?
Linear position
Blocking position - answer Blocking position
There are two common vehicle positioning strategies used at highway incident scenes.
The positioning when a responder vehicle is placed on an angle across one or more
lanes of traffic is known as?
Linear positioning
Block positioning
Shoulder taper
Echelon parking - answer Block positioning
Linear positioning of a responder vehicle involves positioning the response vehicle
directly upstream of vehicles involved in the incident and in the lane beside the crash-
damaged vehicles involved in the incident.
directly upstream of vehicles involved in the incident and within the same lane as the
crash-damaged vehicles involved in the incident.
on the shoulder of the highway so as to not obstruct traffic passing the scene
within any open and unobstructed travel lane - answerdirectly upstream of vehicles
involved in the incident and within the same lane as the crash-damaged vehicles
involved in the incident.
A common example where linear positioning could be used would be at the scene of:
A vehicle fire
A motor vehicle crash with people trapped
A hazardous material leak or spill
A disabled vehicle parked on the shoulder - answerA disabled vehicle parked on the
shoulder
An example where Lane + 1 block positioning typically could be used would be at the
scene of:
A traffic stop for a driving violation
A medical emergency where the injured party is in a vehicle
A staged tow truck waiting for an assignment
All of the above - answerA medical emergency where the injured party is in a vehicle
The use of blocking vehicles is an important way to reduce the risk of a secondary
incident by providing clear, concise direction to motorists, improving traffic flow around
the incident, reducing congestion, and
, notifying police officers that an incident has occurred
protecting response personnel
providing additional advance warning to approaching traffic
obstructing a lane of traffic - answerproviding additional advance warning to
approaching traffic
obstructing a lane of traffic
The decision process for choosing linear positioning or a blocking position begins upon
your arrival, as your vehicle is approaching the incident scene, and;
as you are conducting a windshield size-up
once the vehicle is stopped
during receipt of your initial dispatch information
when a second responder vehicle arrives at the incident scene - answeras you are
conducting a windshield size-up
The Block positioning strategy provides for responder safety by :
Placing more emergency vehicles at the scene
Providing for more personnel at the scene
Putting more emergency lights at the scene
Creating a physical barrier between approaching traffic and responders -
answerCreating a physical barrier between approaching traffic and responders
Three factors that help determine whether to park in a linear or lane 1 block position
are;
Time of day, condition of shoulder, type of lines on the roadway
Number of vehicles involved, age of vehicles involved and color of vehicles
Speed of traffic, volume of traffic, location of vehicles involved in incident
Type of first arriving emergency vehicle, type of street lights and posted speed limit -
answerSpeed of traffic, volume of traffic, location of vehicles involved in incident
When using linear positioning at an incident, it is important that:
Sufficient space remain between the emergency vehicle and a crash-damaged vehicle
The emergency vehicles' headlights remain on
The emergency vehicles' parking brake is set
The front wheels pointed straight ahead - answerSufficient space remain between the
emergency vehicle and a crash-damaged vehicle
When emergency vehicles park in a linear manner with a "slight block" that means that :
Extra lanes are blocked
The emergency vehicle is a car instead of a larger truck
There is minimal space between the blocking vehicle and the first incident vehicle
The emergency vehicle is parked on a slight angle that does not close any additional
lanes - answerThe emergency vehicle is parked on a slight angle that does not close
any additional lanes
