New Yorkers using motorized self-balancing scooters, or so-called hoverboards, will have to slow their roll when using public transit.

The Metropolitan Transportation Authority announced on Wednesday that is prohibiting the possession of hoverboards aboard subways and buses or at stations due to a potential fire risk.

The MTA says it will inform straphangers of the ban through an advertising campaign.

The U.S. Pipeline and Hazardous Material Safety Administration recently issued an alert that under certain conditions, lithium batteries used in the hoverboards can pose a heat, fire and explosion risk.

The agency says its rules have already prohibited the use of personal wheeled vehicles and possession of flammable materials.

Hoverboards are already banned by Amatrak, American regional railroads and most U.S. airlines.
