Car Breakdown Near Malaysian Tunnels or Underpasses MyMechanic

Stabilise before anything else

• If the car still moves, roll to the tunnel exit or next bright lay‑by; stopping in open air is safer than halting mid‑tube.
• If stopping is unavoidable, hug the far edge, keep straight, and avoid curves/crests that hide tail lamps.
• Hazards + low beams on; avoid high beams that glare off walls and reduce others’ visibility.

Airflow and fume control

• If smoke/fuel smell/poor ventilation: engine off; crack a safe‑side window.
• Avoid prolonged idling; use short electrical cycles for visibility in confined spaces.
• Never refuel, jump‑start, or smoke near tunnel mouths/underpasses; vapours linger.

• Wear a reflective vest before stepping out.
• If space is narrow or sight lines short, stay inside and skip the triangle.
• If safe and straight, place a triangle farther back than usual; keep the bonnet closed unless a fast, essential check is clearly safe.

Quick triage: fix here or extract

• Fix here only if simple/safe in a wide, lit bay.
• Extract if shoulder is narrow, light poor, traffic dense, or there are leaks/smoke/repeated stalls.
• Plan two‑stage recovery when tight: compact extraction inside, then flatbed transfer outside in open air.

Passengers, kids, and pets

• Seatbelts on unless a protected walkway/refuge is clearly nearby; move only on the safe side.
• Keep voices low; echoes can unsettle kids—offer small sips of water and calm reassurances.
• Secure pets; never open carriers near live lanes or echoing walls.

Underpass specifics and rain pooling

• If water rises above tyre sidewall, do not restart—request extraction.
• If the engine stalls after a splash, avoid repeated cranks; tow to open air for assessment.

• Position: inside tunnel, at the mouth, or just after underpass.
• Vehicle status: rolls or locked in Park; lights working or dead; leaks or smoke.
• Access constraints: low ceiling, spiral ramp, narrow verge—sets the right gear (dollies, low ramps, compact unit).

• Scene‑aware dispatch: compact recovery inside, flatbed outside.
• People‑first prompts: ventilation, visibility, minimal exposure before mechanical attempts.
• Clean handover: job card and photo checkpoints so restart happens in bright, open space.
