The City of Ottawa’s snow plow school has officially begun for the upcoming winter.

The courses run for five days from September until the end of November. Currently, there are about 400 operators who have to go through the program, Cliff Wall, training manager, told CTV News Ottawa.

The course includes some classroom training and obstacle runs at the city yard with a railroad crossing, catch basins, curbs, and medians. Pylons are also set up to simulate cars and mailboxes and operators must weave through them while operating the plow and wing simultaneously. Trainees will also simulate real situations on the streets before and after the first snowfall.
