Rear Bumper/Rear Underride Guards - Utah

Utah has adopted 393.86 of the Federal Motor Carrier Safety Regulations (FMCSRs).

In Utah, a motor vehicle must be equipped with a bumper on both front and rear.

On a motor vehicle required to have bumpers, a bumper must be:

• At least 4.5 inches in vertical height,
• Centered on the vehicle’s center line,
• Extend no less than the width of the respective wheel track distance,
• Securely mounted,
• Horizontal load bearing, and
• Attached to the motor vehicle’s frame to effectively transfer impact when engaged.

A motor vehicle that was not originally designed or manufactured with a bumper or bumpers is exempt from this requirement.
