New data from Geotab shows Winter Storm Fern resulted in triple-digit increases in ‘collision-level events’ among commercial vehicles on major Ontario highways compared to the average over the previous two weeks.

Geotab analyzed commercial vehicles’ telematics data from Monday, Jan. 26 through Wednesday, Jan. 28 and compared it against the average collision rates of from Jan. 12-21. The results have shown that collision-level events rose 323% on Monday, Jan. 26 and increased by 319% on Tuesday, Jan. 27, peaking on Wednesday with a 451% increase.

“The data we are seeing is unprecedented for a single weather event this season,” said Mike Branch, vice president of data and analytics at Geotab, in a news release. “We aren’t just seeing a slight uptick in collisions; we are seeing collision rates triple and quadruple in a matter of days. Wednesday saw a 451% surge alone. This confirms that road conditions deteriorated faster than many commercial operators could adapt.”

In a separate release, Geotab said it also recorded a 53% increase in national commercial vehicle collision volume in the U.S. since Friday evening. The company compared collision levels to the average of the previous two weekends and identified Maryland reporting the sharpest increase by volume, followed by Kentucky and Indiana.
