Traffic collision reconstructionist with 19 years of traffic collision investigation experience as an LAPD officer. I can answer questions about traffic collisions with vehicles, motorcycles, pedistrians, bicycles, and commercial vehicles. Especially cases of low speed collisions and injury potential. I can answer questions about the vehicle code (specific for Ca and in general for other states) but I am not a driving instructor nor a vehicle mechanic. You need to talk to someone else about these issues.
