Transp. Code §550.041(a) does not limit an officer's authority to investigate a wreck if the officer does not know before he gets to the scene that the accident resulted in injury, death, or property damage of at least $1,000. The statute actually expands the circumstances where an officer may investigate wrecks and file charges. Moreover, according to Transp. Code §550.062, once an officer is dispatched to an accident scene, he has the duty to investigate and file a report within 10 days. Alonzo v. State, 03-06-00761-CR.
