A snowplow is a device that is mounted to a vehicle so that snow and ice can be removed on outdoor surfaces, typically those serving transportation purposes. Snowplows work by using a blade to push snow to the side or straight ahead, clearing it from a surface. Modern plows may include a great deal of technology to make the job—and staying on the road—easier, such as Global Positioning System receivers, head-up displays and infrared cameras. Snowplows are typically made out of steel because of its ability to not bend under heavy loads but many residential plows which are made out of a special plastic are becoming available.
Over the years, there have been numerous different types and styles of plows introduced on the market. The most common of these plows is a standard blade which is placed on the front of the vehicle to push snow out of the way before the tires get to it. Another snow plow which is commonly found on the roads today is the underbody scraper which sits between the axles under the vehicle. The main advantage of using a plow like this is that the vehicle can travel at higher speeds and plow heavier amounts of snow while doing it. Many areas which see large amounts of snowfall are now adapting articulated plows which can be used on highways to clear multiple lanes with one pass. With the advances in technology, snowplows now have the ability to mow large quantities of snow easier and safer than ever.
