Information regarding heavy commercial vehicles.

READING - Heavy Vehicles Tire Blowout and Explosion

IRSST LogoDid you know that in Québec, 360 accidents involving a vehicle tire occurred over a period of 10 years, including some ten fatal accidents directly attributable to heavy vehicle tire blowout or explosion? This fact sheet presents the phenomenon of mechanical blowout of heavy vehicle tires mounted on wheels, and the process and events that lead to tire blowout or explosion as a result of heat buildup.

READING - Monster Trucks on BC Highways?

Oversize TruckIt looks like driving is about to become very interesting on some BC highways. The Commercial Vehicle Safety and Enforcement (CVSE) branch of the BC government has just announced oversize permit T-69A which will allow vehicles up to 5 meters in width to use certain portions of our highways. Remember that the average lane width on a current highway is about 3.65 meters.

RESEARCH - Driving While Fatigued

Truck TractorDriver fatigue is an important causal factor in many highway crashes—and is of particular concern in the trucking industry where many operators undertake long haul drives with limited amounts of sleep. Previous studies suggest that fatigue can affect steering performance and speed control.

In real world driving studies and in driving simulator studies, steering performance has been found to gradually worsen with time.

MOTI BannerAre you concerned with heavy truck safety on BC highways? The Commercial Vehicle Safety and Enforcement branch of the Ministry of Transportation and Infrastructure has produced a report described by the following excerpt:

Commercial Vehicles - Meeting a Wide Load

Pilot VehicleCould you do an article on wide commercial loads when a pilot car is used? The reason I am asking is that I almost got run down once when a wide load came over into my lane, oncoming, to swing wide in order to make a right turn. Understandable, except there was no warning because the pilot car had already made the turn and was nowhere in sight.

RESEARCH - Safety Impact of Speed Limiter Devices

Truck TractorSpeed limiters or governors, are devices that control a vehicle engine to only permit reaching a pre-programmed maximum speed. The limited response to this study suggests that limiters reduce the occurrence of crashes, save fuel and reduce tire wear.

Running on the Ragged Edge

Truck TractorI've noticed something that concerns me in my travels lately, and that is the single long, narrow, curved tire marks that begin about two thirds of the way into a corner and end when the curve does. They don't appear in the traffic lane in the lateral position that one would expect of a vehicle travelling where it should either.

Behaviour Around Heavy Trucks

Truck TractorAsk any trucker about the most dangerous stunt pulled by the drivers of cars and pickup trucks and they will immediately complain about drivers who pass, cut in front of the truck and then slow down. Many drivers of light vehicles seem to have no appreciation at all for sharing the road with heavy trucks.
