Laser Jammer laws in Missouri
In Missouri, the legal landscape regarding laser jammers is characterized by an absence of specific prohibitory legislation. Unlike some jurisdictions that have enacted explicit bans on devices that interfere with speed measurement, Missouri's statutes do not contain any provisions that make the possession, sale, or use of laser jammers illegal for private vehicles. This means that, under current Missouri law, a driver is not committing an offense simply by having a laser jammer installed in their vehicle or by using it. The Missouri Revised Statutes, particularly Chapter 304 (Traffic Regulations), do not include any sections that define or outlaw 'laser jammers' or 'speed countermeasure devices.' While law enforcement may view such devices as an attempt to circumvent speed enforcement, there are no direct legal grounds to issue a citation solely for the presence or operation of a laser jammer. Drivers should, however, be mindful that using such a device to actively evade a legitimate speed measurement could potentially lead to other charges, such as obstruction of justice, depending on the specific circumstances and the officer's discretion, although this would not be a direct charge for the jammer itself. The state has not moved to regulate these devices, leaving them in a legally permissible status for now. Therefore, individuals in Missouri can legally possess and operate laser jammers without violating state law. This contrasts with some other states that have enacted specific legislation to ban or regulate these devices. The Missouri Legislature has not yet taken action to classify laser jammers as illegal equipment for motor vehicles.
