First, you should ensure everyone is ok. If needed, the police should be called for a report. Most non-injury reports can be done in person at the police station. When things calm down, you should call a tow company you know and trust. If you do not have one, the law enforcement agency should have someone approved by them. NEVER let a tow truck who just shows up take your vehicle! Many people become a victim from wreck chasing and can have tow bills in excess of $1000 if the wrong person tows you....
The easiest way to find your vehicle is to call the law enforcement agency that your vehicle was towed from and see which company has it at their facility. The City of Kansas City's impound lot is located at 7750 E. Front St., Kansas City, MO 64120.
