Lamar Odom is likely to see his car insurance bill go way up … he crashed his Mercedes into two parked cars in an early morning accident.

A rep for Lamar tells TMZ … Lamar was behind the wheel when he got into a car crash around 3 AM Monday in a residential area near his home.

We’re told Lamar was driving home from a friend’s place in Northridge when he dropped his phone inside his Mercedes, reached down to retrieve it, lost control and smashed into a pair of cars parked on the street.

Lamar’s rep says his white Mercedes hit another white car, which bumped into another car parked in front of it.

Lamar’s airbags deployed, and he wasn’t injured and didn’t need medical assistance … though he was a little shaken up and his Mercedes is now mangled.

Cops were called but LAPD did not take a police report after responding to the scene. We’re told officers spoke with Lamar, asking him if he had been drinking, to which Lamar said no and told cops about being sober and owning rehab facilities.

Cops did not perform a field sobriety test.

Lamar, we’re told, then explained to LAPD how the accident happened … and the owners of the impacted cars came out of their homes and Lamar gave them his insurance information.

Fortunately, we’re told no one was inside the parked cars at the time of the crash … though Lamar’s Mercedes was towed and his security drove him home.

In the end, cops left after seeing everyone exchange information.
