What does 49 CFR 392.25 (Flame producing devices) require?

Short answer

49 CFR 392.25 requires drivers not to use flame-producing emergency signals for certain commercial motor vehicles, such as those transporting Division 1.1, 1.2, or 1.3 explosives, and instead use emergency reflective triangles, red electric lanterns, or red emergency reflectors.

The rule says

"No driver shall use or permit the use of any flame-producing emergency signal for protecting any commercial motor vehicle transporting Division 1.1, Division 1.2, or Division 1.3 explosives; any cargo tank motor vehicle used for the transportation of any Class 3 or Division 2.1, whether loaded or empty; or any commercial motor vehicle using compressed gas as a motor fuel." (49 CFR 392.25)

In plain English

This rule is about safety: it prohibits the use of flame-producing devices, like flares, near vehicles carrying hazardous materials that could ignite or explode. Instead, drivers must use safer alternatives like reflective triangles or electric lanterns to alert other drivers to hazards.

What to do

• Ensure drivers are aware of the prohibition on flame-producing emergency signals for specified vehicles.
• Provide alternative emergency signaling devices, such as reflective triangles or red electric lanterns.
• Train drivers on the proper placement and use of these alternative devices as prescribed in 392.22(b).
• Regularly inspect and maintain these devices to ensure they are in good working condition.
