Driving past another vehicle where signs or road markings forbid it.

"Driving past" means moving into the opposing lane to overtake slower traffic instead of staying behind it. "Another vehicle" usually means a car, truck, motorcycle, farm vehicle, or similar road user ahead of you. "Where signs or road markings forbid it" usually means a solid yellow centerline, posted no-passing signs, or a stretch of road where hills, curves, intersections, or limited sight distance make passing too dangerous. On long, empty roads, including parts of Aroostook County, that rule still applies even when traffic feels sparse.

Practically, this violation can lead to a traffic ticket, fines, and points or other consequences on a driving record, depending on the facts and any related violations. In Maine, no-passing rules are part of Title 29-A of the Maine Revised Statutes (2024), which governs when a driver may overtake on the left and when that maneuver is prohibited.

For an injury claim, passing in a no-passing zone can strongly support negligence because it suggests the driver ignored a clear safety rule. If that illegal pass causes a head-on crash, sideswipe, or forced-off-road collision, the violation may be key evidence on liability. It can also affect insurance decisions, settlement value, and arguments about comparative negligence if both drivers share some fault.
