Can You Have No Mirrors on a Motorcycle?
There’s no law against it, but we don’t recommend it. Here’s why:
Riders need to be able to see what’s behind them, and mirrors provide that critical view.
Without mirrors, a rider would have to constantly turn their head around to check for traffic, which would not only be tiring, but could also lead to accidents.
Another reason is that many riders use their mirrors as a way to check their posture while riding. This is especially important for newer riders who are still getting used to the feel of being on a motorcycle.
By having mirrors, they can quickly and easily make sure they’re sitting up straight and in the proper position.
So while there’s nothing stopping you from riding without mirrors, we strongly advise against it. It’s simply not safe or practical.
