The pole snapped at the base and the woman's black Mazda truck then veered into the ocean, police said.

The woman had been driving north on Kamehameha Highway when she saw the dog in front of the Crouching Lion shortly before 11 a.m., police said.

The woman, in her mid 40s, had bruises and swelling to her lower legs but appeared otherwise uninjured, EMS district chief Robert Pedro said. She was taken to Kahuku Hospital, where she was treated and released.

The pole was a not a main utility pole, but a smaller, support pole the utility company calls a "stub pole," said electric company spokeswoman Lynne Unemori. Guy wires from the pole were draped across the road, but the main pole was not affected and power was not disrupted to the area, she said.

The road was closed for four hours while authorities cleared the pole and tended to the woman and her truck.
