Parking at the Scene of a Call —
tactical positioning of the vehicle

Where and how the driver positions the ambulance determines crew safety, access to the patient, and how quickly they can leave. Tactical vehicle positioning is a skill — not an accident.

An EMS driver isn’t just someone who brought the crew to the scene. The vehicle’s position is the first tactical decision of the entire call — it affects the crew’s protection from traffic, access to the patient with the stretcher, lighting of the scene, and the escape route. A bad position is hard to fix once the call is underway.

Four goals of tactical positioning

What the vehicle’s position must ensure — in this order

1. Protection of the crew and patient — the vehicle as a physical barrier between traffic and the work site.

2. Access to the patient — rear doors facing the patient, room for the stretcher, level ground.

3. An escape route — the vehicle must not be blocked; leaving with the patient must be possible without reversing through a crowd or turning in a tight space.

4. Visibility and lighting — warning lights visible to approaching traffic; at night, lighting for the scene.

The fend-off position — the basis of protection on the road

When working on the roadway or shoulder (a traffic accident, a patient on the road), the EMS vehicle is positioned in what’s called a fend-off position — angled, with the wheels turned away from the scene. Goal: if another vehicle strikes the ambulance, the impact deflects it away from the crew’s work area, not into it.

Diagram 1 — Fend-off position for a roadway incident
direction of traffic crashed vehicle WORK AREA RZP ambulance angled — 15° to 25° wheels turned OUT approaching vehicle impact deflects the ambulance AWAY from the crew ≥ 15 m
Fend-off position: the vehicle positioned at an angle of 15–25°, front wheels turned away from the scene. On a rear impact, the ambulance is deflected into open space — not into the crew’s work zone. Standoff distance from the scene: at least 15 meters.
⚠ Why wheels turned outward matters

If another vehicle strikes a stationary ambulance, the ambulance moves in the direction the front wheels are turned. Wheels turned toward the scene = the ambulance drives into the crew and patient. Wheels turned away from the scene = the ambulance deflects into open space. This detail — turning the wheel after stopping — takes two seconds and can decide the crew’s life.

The blocking position — when a lane must be closed

When working directly on the roadway (CPR on the road, extrication), it may be necessary to block the entire traffic lane — the ambulance is positioned across the lane in front of the scene, physically preventing traffic from entering the work zone. The blocking position is typically established by the first vehicle on scene; once fire or police arrive, their apparatus takes over blocking and the ambulance can reposition closer to the patient.

Diagram 2 — Blocking position (lane closure)
direction of traffic patient / CPR WORK ZONE RZP ambulance across the lane — 45° to 60° traffic BLOCKED open lane — traffic passes around
Blocking position: the ambulance positioned across the lane at a 45–60° angle in front of the work zone. It physically prevents vehicles from entering the space where the crew is working. Distance from the patient: at least 15 m, more on a higher-speed road.

Safe distances by road type

Road typeVehicle standoff from the sceneWarning triangle placement
Town / city (up to 50 km/h)10 – 15 mmin. 50 m before the scene
Rural road (90 km/h)15 – 30 mmin. 50 m, ideally 100 m
Motorway / expressway30 – 50 mmin. 100 m before the scene
A blind section (curve, hill)Increase the standoff — the vehicle must be visible before the curve/hillbefore the curve / crest of the hill
§ 24(3) — Act No. 8/2009 Coll. — stopping an EMS vehicle

The driver of a vehicle with the right of priority driving may stop and park at a location where this is otherwise prohibited, if necessary to carry out their duties — provided they do not endanger road safety. The vehicle’s position at the scene of a call is therefore legally covered — but the tactical correctness of the position is up to the driver.

Positioning off the roadway — apartment buildings, houses, complexes

Most calls don’t end on the road, but at an apartment building, a house, or an enclosed complex. Tactics apply here too — different, but equally important.

Positioning principles near buildings

Rear doors to the entrance. The stretcher comes out through the rear doors — position the vehicle so the distance between the stretcher and the entrance is as short as possible and without stairs, curbs, or lawns, if they can be avoided.

Never block your own way out. In a dead-end street or courtyard, park nose-out. Turning around with a critically ill patient costs minutes. Reversing in on arrival = driving straight out on departure.

Leave room for the physician response vehicle / air ambulance. If you’re expecting a physician to arrive (a meet-up system) or a helicopter, leave them space — the physician response vehicle needs access to your rear doors.

Watch out for soft ground. A lawn after rain, snow, mud — a 3.5-tonne vehicle will get stuck. Better to park 20 meters further away on solid ground than have a bogged-down ambulance five meters from the entrance.

Parking brake + gear. Always. Even on level ground. On a slope, turn the wheels toward the curb.

A nighttime call — the vehicle as a light source

At night, the EMS vehicle is the strongest light source at the scene. The vehicle’s position determines whether the crew works in light or in their own shadow.

Lighting the scene — practical principles

Headlights on the work site — if the position allows, aim the headlights at the patient/work area.

Watch for blinding others — high beams toward approaching traffic blind drivers, who then can’t see the crew on the road. On the roadway, light the work site, not oncoming traffic.

Warning lights kept on — the blue lights run throughout the entire call, even off the roadway. They mark the location for additional crews and other emergency services.

Shadow is the enemy — check that the vehicle isn’t casting a shadow exactly where the paramedic is working with the patient.

Three scenarios from practice

Scenario A
A traffic accident on a class I road, first vehicle on scene

An RZP arrives as the first emergency service at a two-car accident on a rural road. Neither police nor firefighters are on scene yet.

Tactical procedure: Fend-off position 20–30 m before the accident, wheels turned away from the scene, warning lights on, triangle 100 m ahead of the vehicle. Until police arrive, the ambulance also serves a protective function — shielding the crew working around the crashed vehicles. Once fire brigade arrives, reposition closer per the incident commander’s instructions.
Scenario B
Unconsciousness in an apartment building on an estate, tight parking

A call for unconsciousness on the 4th floor of an apartment building. Cars are parked in front of the entrance; an open spot is 40 m away or on the lawn right by the entrance.

Tactical procedure: If the lawn is firm and dry — park by the entrance, rear doors to the entrance. If it’s soft — better 40 m away on solid ground; a bogged-down ambulance with a critical patient is worse than a longer carry. When parking on a sidewalk/lawn, leave a passage for pedestrians and possible access for a physician response vehicle. Don’t lock the vehicle — the second crew member may need equipment.
Scenario C
A call in a dead-end street of a residential area

A call for a patient with chest pain at a house at the end of a dead-end street 4 meters wide.

Tactical procedure: Reverse into the street — nose of the vehicle facing out. If the patient’s condition worsens and rapid transport is needed, drive straight out without turning. Reversing on arrival (a calm situation, guided by the paramedic from outside) is always safer than reversing on departure with a critical patient on board.
From practice — the two seconds that matter
Injury statistics for paramedics working on the roadway consistently show that secondary collision — another vehicle striking the scene — is among the most severe risks of EMS work on the road. The fend-off position, turned wheels, and correct standoff distance aren’t academic details. They’re two extra seconds of work when positioning the vehicle that create a physical barrier between the crew and traffic. A driver who skips them puts their crew on the front line without protection.
