On a chilly winter day, it can feel painstakingly slow taking the time to scrape all the ice and snow off your car before heading to work.
But skipping the chore can be seriously dangerous for other drivers.
Kevin McGraw was driving near Moncton, N.B., on Wednesday when he approached a truck that was merging onto the highway. A huge chunk of frozen snow flew off the vehicle, smashing his windshield and covering his wife in shards of glass.
Luckily, McGraw was able to pull over before another accident happened.
Watch the video of his close call above.
