BRIEF ACCOUNT OF INCIDENT:

A 16 tonner contractor truck (under influence only), carrying finished lubricants packed goods from our Mumbai Central warehouse to our Kolkata warehouse rolled over to its side near Murtajapur ( about 550 Kms from Mumbai)
The incident occurred on a National Highway (NH -6) single carriage dual lane with no shoulders or dividers, when a state transport bus while overtaking came on the way of contractor truck and pushed him to his side resulting in a roll over of contractor vehicle.
State transport bus came on the way of contractor truck as he was obstructed by a trailer which was coming from the opposite side with single head light on (cock eyed).  The oncoming vehicle had its left side (driver Assistant) single light was on.
No injuries to the contractor driver or to the assistant.  .
Both the bus & the trailer had pursued their journey without halting.

The contractor vehicle front tyre (driver assistant side) was busted post the roll over.

The speed of the vehicle captured in GPS was 43 KM/Hr at the time of incident.



Driver:
Driver Name- Addya Yadav (Module -4 trained (14/07/2008))

Age - 38 years.

From the records, it was observed that this driver had driven in our operations at least two dozen times since 2009 and quite familiar to this route with a fair record of safe driving principles.

Driver had reached our depot on 8th of May and had to wait for his load.

On 9th May – driven for 9 hours 36 minutes and covered a distance of 340 kms. He stopped his travel at 20.45 hours

On 10th May – driven for 8 hrs 10 minutes (before the incident) and travelled about 220 kms.  He begun his journey at 7.45 am
He propose to stop in another  20 kms of distance which would have taken 30 to 45 minutes.


Driver had reached Mumbai from Kolkata on 3rd of May since then has been in Mumbai and had done one local movement for Castrol.
Post the incident - eye test was done to the driver and report was shared. He had perfect vision (6/6).
The incident was communicated by the driver to their operational in charge around 22.30 hrs from the nearest local public telephone service.

Key Observations

Width of the road is 7.6 mtrs (24.92 feet). The width of the contractor truck is 3.4 metres (11.15 feet), while the bus which was overtaking the truck is also of same width. The length of contractor truck is 24 feet while the bus which was trying to over take the truck is about 28 feet ( a similar bus measurement was taken).

The oncoming vehicle (trailer) was 30 feet with a width of 3.4 feet (based on the input given by the driver, measurement of similar vehicle was considered).

The distance between the trailer truck & the bus was about 500 metres when the bus came on the way of contractor truck to pave way for the oncoming vehicle.

Contractor driver was driving on his side of the road (extreme left), while the private bus which had to overtake him had to go to the other side (oncoming vehicle side) to overtake the contractor vehicle.

A late reaction from both the vehicle (contractor driver and bus driver) on  recognizing the risk of the oncoming vehicle led to the compulsive action by the bus driver , pushing the contractor to go further left on the soft shoulder and rolled over to its side of about 1.5 feet depth.

As per our journey risk assessment, the said location was a green zone and the speed of the contractor driver was  well below the recommended speed limit. The weather conditions were very hot and dry.

No brake marks observed on the accident spot. From the GPS report, it was observed that there was an attempt made by the contractor driver to reduce the speed.

The contractor vehicle was under the maintenance of OE manufacturer. The tyre burst was shared by the tyre manufacturer post the vehicle rolled over.

WHAT WENT WRONG (CRITICAL FACTORS) :

  • CF1 – malfunctioning of head lights (just one light was functioning) of the oncoming vehicle
