Slow driving is one of those traffic topics people underestimate because the speed limit sounds like only a ceiling. In practice, most states also protect the normal flow of traffic. That means a driver can absolutely get a ticket for going too slowly when there is no real safety reason and other traffic is being impeded.

Penalties usually mean a traffic citation, fine, and possibly points depending on the state and whether the officer writes it as impeding traffic, lane misuse, or careless driving.
If you are driving below the flow of traffic for a real safety reason, use hazard lights if appropriate and move right or pull over when safe. If you are cited, preserve dashcam footage, road-condition photos, and any proof of vehicle trouble or weather conditions.
If you've been charged, consult with a qualified attorney in your state.
The law does not require you to speed, but it often does require you not to needlessly hold everyone else up.
