The mirror rule in Montana

Montana's mirror law (Mont. Code Ann. § 61-9-404) asks for a mirror that shows the road behind you; it doesn't specifically demand a side mirror. A clear interior rearview can meet that as written. Stack gear in the back, fog up a soft-top window, or tow something and you'll want outside mirrors. Most doors-off drivers run them anyway, because a Jeep's factory side mirrors leave with the doors.

“A motor vehicle must be equipped with a mirror that reflects to the driver a view of the highway for a distance of at least 200 feet to the rear of the motor vehicle.”

STAY STREET-LEGAL

Put your mirrors back

Your factory side mirrors ride on the doors. These mount to the hinges or the A-pillar so they stay when the doors don't. Every link goes to Amazon.

Fenders and mud flaps

All vehicles except motorcycles, quadricycles, motor-driven cycles and farm tractors must have fenders, splash aprons or flaps on the rearmost wheels; for vehicles 8,000 lbs GVWR or less they must reach within 20 inches of the road. Street rods and vehicles not originally equipped with or federally required to have them are exempt. (Mont. Code Ann. § 61-9-407)

Do you need doors at all?

We didn't find any Montana statute requiring doors, but we couldn't rule one out from the official code either. The equipment rules (mirrors first) are what usually draw a stop.

The rear fender/flap rule (61-9-407) applies to the rearmost wheels; lifted Jeeps with trimmed or removed rear fenders/flares may be affected. Section 61-9-407(3) exempts vehicles not originally equipped with fenders/flaps.
