Question: Do I need to have a mirror on the outside passenger side of the door on my pickup truck? It has one on the driver’s side and a rearview on the windshield.
Answer: Being that your pickup has one on the windshield and one on the driver’s side, you are legal in Minnesota. According to the Minnesota Driver’s Manual, all passenger vehicles must be equipped with rearview mirrors. Vehicles such as rental moving trucks, which are not designed to allow a view through the rear window, must be equipped with an additional side mirror. Pickup trucks, which are often used for hauling purposes, must also be equipped with an additional side mirror. The side mirror will provide the driver with a clear view when transported materials obstruct sight through the rearview mirror.
Vehicles equipped without or limited mirrors can result in a crash as the driver is unable to see behind them from different angles. Driver and passenger side mirrors help drivers see other vehicles when changing lanes, assist the driver in determining how close other vehicles are, and in the event an emergency vehicle approaches, a driver is able to slow down and safely pull over and yield the right-of-way.
In my experience over the years, I have encountered many unsafe situations while responding to emergencies with my lights and siren on where vehicles in front of me had no idea that I was behind them. When the driver finally realized there was a patrol car behind them, they would become startled and apply the brakes very hard and/or swerve into the other lanes or shoulder very quickly, creating a very dangerous situation.
I recommend that drivers have two outside mirrors, along with a rearview mirror attached to their windshield at all times. If a driver is pulling an RV or trailer and the view to the rear is obstructed, I recommend purchasing rearview mirror extensions so the driver is able to clearly see behind the vehicle.
Please avoid distractions while driving and make it a habit of checking rearview mirrors often. This will increase a driver’s odds of avoiding a crash.
You can avoid a ticket — and a crash — if you simply buckle up, drive at safe speeds, pay attention and always drive sober. Help us drive Minnesota toward zero deaths.
