Michigan motorcycle handlebar and mirror laws can affect whether a rider gets stopped, ticketed, or questioned about motorcycle equipment after a crash. In this Motorcycle Legal Minute™, Jason Waechter, The Motorcycle Lawyer®, explains Michigan’s handlebar height rule, the driver’s-side mirror requirement, and why riders should know the equipment laws that apply to motorcycles and mopeds in Michigan.
The Motorcycle Legal Minute™ was created by Jason Waechter, The Motorcycle Lawyer®, to explain Michigan motorcycle law in a short and easy-to-understand way.
Michigan has specific equipment rules for motorcycles and mopeds, including rules about handlebar height and rearview mirrors. These rules may seem minor, but they can matter if a rider is stopped by police, receives a ticket, or is involved in a crash where motorcycle equipment becomes part of the discussion.
Two common questions riders ask are: how high can motorcycle handlebars be in Michigan, and does a motorcycle need a mirror?
Under Michigan law, a person may not operate a motorcycle or moped on a public highway if the handlebars are higher than 30 inches.
The measurement is taken from the lowest point of the undepressed saddle to the highest point of the handle grip. In everyday terms, that means the measurement is from the seat area to the handgrip.
So, if your motorcycle has tall “ape hanger” handlebars, it is smart to measure them before riding. If the handlebars exceed Michigan’s legal height limit, the rider could risk being stopped or ticketed.
Yes. Michigan law requires motor vehicles to have an outside rearview mirror on the driver’s side, positioned to give the driver a rearviewing angle from that side of the vehicle.
For motorcycles, Michigan law also allows rearview mirrors to be positioned on the helmet or visor worn by the motorcycle operator, as long as the helmet is securely attached to the operator’s head.
In practical terms, a Michigan motorcycle should have at least a driver’s-side mirror, which is the rider’s left-hand side, unless a lawful helmet or visor mirror is being used.
Motorcycle equipment laws are not just about avoiding tickets. After a motorcycle crash, insurance companies and defense attorneys may look for any argument they can use against an injured rider. If they can claim the motorcycle was not legally equipped, they may try to use that issue to distract from the driver’s negligence.
That does not mean every equipment issue caused the crash. But it does mean riders should take these requirements seriously and keep their motorcycles legally equipped whenever possible.
Possibly, depending on the facts. If a motorcycle equipment issue had nothing to do with the crash, it may not be a major issue. But if the defense can argue that high handlebars affected control, visibility, reaction time, or safe operation, they may try to use that against the rider.
The same is true for mirrors. If a crash involved a lane change, merging, rear traffic, or a rider’s ability to see behind him or her, a missing mirror may become part of the argument.
The key question is whether the equipment issue actually had anything to do with the crash, the rider’s conduct, or the injuries claimed.
Handlebars and mirrors are only part of Michigan’s motorcycle equipment rules. Riders should also understand laws involving headlights, eye protection, windshields, mufflers, exhaust noise, helmets, turn signals, brakes, and other required equipment.

The takeaway is simple. In Michigan, motorcycle and moped handlebars cannot be higher than 30 inches when measured from the lowest point of the undepressed saddle to the highest point of the handgrip. Motorcycles also need a proper rearview mirror on the driver’s side, or a lawful helmet or visor mirror.
These rules are easy to overlook, especially on customized motorcycles. But knowing the law can help riders avoid unnecessary tickets and reduce arguments that may be used against them after a crash.
