Gore point
A “gore” or “gore point” is a triangular space defined by wide solid white lines, usually 8 inches in width, where roads merge or split. They are most commonly seen on divided highway and freeway entrances and exits ramps.
In *most states it is illegal to enter this area. On-ramp lengths are designed to allow motorists to safely gain freeway speed before merging into traffic. To cut across the gore is to defeat the purpose of the on-ramp and can surprise oncoming traffic not expecting vehicles to enter that area.
*Those states where there is no statute clearly condemning entering the gore: Alabama, California, Hawaii, Indiana, Louisiana, Maine, Massachusetts, Michigan, Mississippi, North Carolina, North Dakota.
