A B-train truck driver was rounding a corner on a forest service road when the mounting bolts for the scale pads failed. The trailer became unattached from the tractor, crossed the center line and went off the left side of the road, crashing in a deep ditch and causing over $40,000 in damage to both trailers.

The driver stated that he had slowed to below the posted speed limit of 80 km/h when rounding the corner. The driver had been travelling over rough roads, which is believed to be what led to the stress and wear on the bolts, causing them to eventually break off.

Key Learnings:

• This could have been a very serious incident had there been oncoming traffic or if it had occurred somewhere else.
• It is very important to complete Pre/Post-Trip truck inspections as bolts can become worn through use.
• Follow-up inspections should be completed to ensure drivers are completing their required inspections.
