Three teenagers were knocked off a motorcycle after a pick-up truck cut in front of them and then sped away.<br /><br />The sisters were riding home on the motorcycle before being hit by the vehicle in Nakhon Si Thammarat, southern Thailand on Tuesday (July 23).<br /><br />Dash cam footage from the evening shows how the black truck quickly changed lanes, attempting to make a left turn to the small street.<br /><br />The driver, who also failed to indicate, cut in front of the cautious motorcyclists and knocked them off.<br /><br />Chutima Pettit, who filmed in the crash, parked her car and rushed to help the schoolgirls as the truck driver had already left from the scene.<br /><br />The students had a few grazes and bruises but were not seriously hurt and rode back home afterwards.<br /><br />Chutima said: ''The driver was very inconsiderate. He didn't slow down or even had a look to see if the students were okay.''<br /><br />Thida Etae, the mother of girls, reported the police. The pick-up truck driver, whose name is Jutamas, was eventually caught yesterday evening. <br /><br />According to her lawyer, Jutamas was not aware of the accident - thinking that the girls had lost their balance before falling down.<br /><br />The lawyer said: ''She drove away because she didn't know. She couldn't make it to the police station today but she wanted to apologise for driving carelessly.''<br /><br />The car driver gave 10,000 baht (260 GBP) as compensation to the victims. She also accepted the police charge for driving negligently and injuring other people.
