The Roadside Bystander Action Chain: First Steps at a Highway Incident
When an unexpected collision or breakdown occurs on an Indian highway, the initial minutes are dominated by shock and dangerous hesitation. Bystanders frequently want to assist but lack a standardized, safe protocol. Worse, well-meaning helpers often expose themselves to high-speed secondary collisions or inadvertently aggravate spinal trauma by moving victims improperly. This operational protocol details the exact sequence of actions required from Minute 0 to Minute 30.

1. Minute 0 to 3: Scene Assessment, Hazard Triangles, and Perimeter Defense

Before taking any physical action regarding an immobilized vehicle, bystanders must secure their own physical safety. On expressways with design speeds of 120 km/h, approaching traffic covers over 33 meters per second. A driver traveling at highway speeds requires at least 85 to 110 meters of combined perception and braking distance on dry asphalt.

Secondary collisions—where approaching motorists ram into immobilized vehicles or bystanders—represent over 37% of catastrophic highway casualties in India. Therefore, the absolute first requirement is establishing perimeter visual warnings before touching the damaged vehicle.

  • Park your own vehicle at least 30 meters ahead of the incident on the shoulder, with hazard lights flashing and steering wheels turned towards the embankment.
  • Deploy reflective warning triangles at a minimum distance of 50 meters on two-lane state highways, and 120 to 150 meters on four-to-six-lane access-controlled expressways.
  • Ensure all passengers and uninjured bystanders move immediately behind the galvanized steel W-beam crash barrier or onto the raised earthen berm.
  • At night, wear high-visibility reflective vests or utilize smartphone flashlights angled towards the ground to alert oncoming traffic without blinding drivers.

2. Minute 3 to 5: Emergency Dispatch & The 112 / 1033 Notification Relay

Once the perimeter is marked, immediately trigger the institutional emergency response. In India, two national numbers form the backbone of highway dispatch:

Dial 112 (National Emergency Response Support System - ERSS) to dispatch local police and ambulance services. If traveling on a National Highway or Expressway under the National Highways Authority of India (NHAI), dial 1033 (NHAI Expressway Emergency Helpline) for dedicated route-patrol tow trucks and trauma ambulances.

  • State your exact chainage location: look for roadside milestone stones (e.g., 'NH-48 KM 142.6 Northbound towards Pune'). Milestone markers provide emergency services with exact GPS-correlated dispatch coordinates.
  • Report the total number of damaged vehicles, estimated number of injured persons, whether anyone is trapped inside the passenger cell, and any evidence of fuel leaks or smoke.
  • Request immediate dispatch of Advanced Life Support (ALS) ambulances if victims exhibit unconsciousness, severe bleeding, or respiratory distress.

3. Minute 5 to 7: Optical Decal Scan & Family Emergency Handshake

While public ambulances are en route, connecting to the victim's verified next-of-kin is vital. Traditionally, bystanders tried unlocking the victim's phone (usually blocked by fingerprint/PIN) or searching through private bags, raising accusations of theft.

Because VaahanSafe decals are affixed on the passenger-side quarter glass or windshield, a bystander can scan the QR code from the footpath curb in less than 3 seconds without touching personal belongings.

The resolved public safety view also displays consented medical emergency tags (e.g., Blood Group, Diabetic Alert, Cardiac History, Organ Donor status), providing critical triage information for attending paramedics.

4. Minute 7 to 15: Golden Hour First Aid & Cervical Spine Stabilization

The 'Golden Hour' refers to the first 60 minutes following major trauma, where prompt medical intervention yields the highest probability of survival and permanent disability prevention. Follow the international Trauma First Response ABC framework:

A

Airway & Cervical Spine Control

CRITICAL

Ensure the airway is clear of blood, vomit, or broken dentures. Crucially, stabilize the head and neck in a neutral in-line position. If the victim is a motorcyclist, DO NOT remove the helmet unless the airway is fully occluded. Yanking a helmet off an un-stabilized neck can sever the C1-C4 spinal cord, causing instant fatal paralysis.

B

Breathing & Chest Expansion

TRIAGE

Observe whether both sides of the chest rise and fall symmetrically. Loosen tight neckties, collars, and belts. If the victim is unconscious but breathing normally, place them in the lateral recovery position (only if spinal injury is definitively ruled out).

C

Circulation & Severe Hemorrhage Control

HEMOSTASIS

Apply firm, direct, continuous pressure to heavily bleeding wounds using clean cloth, gauze, or clothing for at least 10 minutes without lifting. Do not apply tourniquets around the neck. Keep the victim warm with blankets or coats to prevent trauma-induced hypothermia.

5. Minute 15 to 30: Formal Handover to Paramedics and Legal Departure

Upon ambulance arrival, the Good Samaritan's role shifts to an organized medical handover. Provide a concise SBAR briefing to the attending paramedic:

Under Section 134A of the Motor Vehicles Act 1988, you are legally entitled to depart immediately once clinical personnel take charge. You are under no obligation to accompany the ambulance or surrender your identity.

SBAR Paramedic Handover Framework
ComponentInformation to CommunicateExample
S — SituationWhat occurred and whenRear-end collision at 02:15 PM; vehicle rolled once
B — BackgroundObserved conditions & contacts alertedPassenger-side QR scanned; next-of-kin notified and en route to civil hospital
A — AssessmentConsciousness & bleeding statusDriver unconscious; breathing shallow; heavy laceration on left thigh compressed
R — RecommendationImmediate stabilization requiredSuspected cervical fracture; ALS extrication needed
HIGHWAY INCIDENT FIRST 15-MINUTE PROTOCOL
Switch on hazard warning lights on your vehicle and park 30m ahead on the shoulder
Deploy reflective hazard triangle 50m to 150m behind the incident
Step behind the metal crash barrier onto the raised grass embankment
Dial 112 (National Emergency) and 1033 (NHAI Helpline) with highway milestone data
Scan the VaahanSafe decal from the passenger-side curb without entering traffic lanes
Establish call bridge with next-of-kin via masked telephony relay
Assess victim breathing and apply continuous direct pressure to arterial bleeding
Maintain in-line cervical neck stabilization—never jerk or yank off motorcycle helmets
Deliver concise SBAR handover to arriving paramedics and exercise right to depart
OPERATIONAL EDGE CASES • FREQUENTLY ASKED QUESTIONS

Should I move an unconscious accident victim out of the vehicle immediately?

No. Unless there is imminent, uncontainable fire, risk of explosion, or the vehicle is submerged in water, you should NOT extricate an unconscious victim. Moving victims without a rigid cervical collar and spine board frequently converts stable spinal fractures into permanent quadriplegia. Keep the victim stationary and support their head in a neutral position until emergency services arrive with extrication gear.

What should I do if a motorcycle helmet is on the victim?

Leave the helmet on. Modern full-face motorcycle helmets provide vital cervical immobilization. You should only remove the helmet if the visor cannot be opened, the victim has stopped breathing, and you need immediate airway access for cardiopulmonary resuscitation (CPR). In such cases, helmet removal requires two trained responders: one immobilizing the neck while the other gently eases the helmet off.

Can I be sued if my first aid attempts do not save the victim?

No. Under Section 134A(1) of the Motor Vehicles (Amendment) Act 2019, any person who renders emergency medical or non-medical assistance to an accident victim shall not be liable for any civil or criminal action for injury or death of the victim. The law provides absolute immunity for Good Samaritans acting in good faith.

What if local police arrive and demand my identity or vehicle RC?

Police officers are strictly prohibited under Central Motor Vehicles (Protection of Good Samaritans) Rules 2020 from demanding identification, impounding your vehicle, or forcing you to register an FIR. You have the statutory right to state that you are a Good Samaritan and depart the scene without penalty.
