Emergency Flares laws in Missouri

In Missouri, the use and possession of emergency road flares are not explicitly prohibited by state statute for private vehicle operation and are considered legal. While Missouri law does not mandate that all vehicles carry emergency flares, it is recognized as a recommended safety device for motorists. Commercial vehicles, however, may be subject to specific federal regulations or specific provisions within Missouri's commercial motor vehicle laws regarding emergency signaling devices, which could include flares or alternatives like reflective triangles. While there are no specific state statutes in Missouri penalizing the mere possession of emergency flares for personal use, misuse or improper deployment that creates a hazard could be subject to broader laws concerning public safety and disturbance. For example, deploying flares in a manner that obstructs traffic, causes alarm, or constitutes a fire hazard could lead to citations under general public nuisance or dangerous activity statutes. Penalties in such cases would depend on the specific circumstances and the charges filed, potentially ranging from minor fines to more serious misdemeanor offenses, particularly if the action results in property damage or personal injury. Currently, there are no notable statewide exceptions or exemptions concerning the legality of emergency flares for general motorists in Missouri. Travelers and residents are advised to store flares in a cool, dry place to ensure their efficacy and to regularly check expiration dates, as older flares may not reliably function in an emergency. This proactive approach ensures that if a situation arises requiring their use, the flares will be operational for signaling and enhancing visibility for safety purposes.
